57|Part 2 of —– 21|Muromachi Period History (室町時代) 1393-1467 – – – – – – – – – – – – Ashikaga Yoshimitsu and Ashikaga Yoshimasa
This is the continued chapter of 21 Muromachi Periods History Please read chapter 21 before this chapter one more time.
Until the Muromachi (室町) Period, the way to divide the political history and sword history is the same. Please look at the above timeline. The middle line is for sword history and the bottom line is for political history. The style of the sword has a distinct difference between Nanboku-Cho period (南北朝時代 ), Muromachi period, and the Sengoku period (戦国時代). Therefore, it has to be divided into three separate periods for sword study. But school history textbook shows that Muromachi Period is from 1333 (Fall of Kamakura Bakufu ) until 1573 when Oda Nobunaga(織田信長) removed Shogun Ashikaga Yoshiaki (足利義昭) from Kyoto (the fall of Muromachi Bakufu). The school history textbooks describe that the Nanboku-Cho period and the Sengoku period is a part of the Muromachi period. For the purpose of sword study, we need to divide into three periods, Nanboku-Cho period, Muromachi period, and Sengoku period.
Ashikaga Yoshimitsu (足利義満)
The best time for the Muromachi period was when Ashikaga Yoshimitsu (足利義満, Grandson of Ashikaga Takauji) was in power. Ashikaga Yoshimitsu moved the Bakufu to the place called Muromachi (室町), therefore Muromachi period. By Shogun Yoshimitsu’s time, the majority of the South Dynasty Samurai went under the North dynasty. The South Dynasty side accepted Shogun Yoshimitsu’s offer to end to oppose to the North Dynasty that completed the power of Muromachi Bakufu of the Ashikaga family. Shogun Ashikaga Yoshimitsu created a huge amount of profit from trade with China (Ming). One of a famous beautiful temple in Kyoto, Golden Pavillion (Kinkakuji-temple 金閣寺) was built by Shogun Yoshimitsu*. It is said that he created the Golden Pavillion to display his power and wealth. The beautiful culture around this time was called Kitayama Bunka (Kitayama culture 北山文化).
*Golden Pavillion (Kinkaku-Ji 金閣寺) —— Correct name is Rokuonji –Temple (鹿苑寺 ). This is a Zen temple of Rinzaishu Sokoku-Ji group (臨済宗相国寺派 ). The Kinkakuji-temple is one part of the Rokuonji-Temple. Kinkakuji-temple is a Buddhist hall containing relics of Buddha. This place was once owned by Saionji Kintsune (西園寺公経 ) in Kamakura period. Shogun Yoshimitsu acquired it in 1397, and he rebuilt it as his own villa. It is also functioned as an official guesthouse. Kinkakuji-temple represents the height of the glory of Kitayama Bunka (Kitayama culture). After Shogun Yoshimitsu’s death, his villa was converted to a temple, called Rokuon-Ji temple. In 1994, it was registered as a World Cultural Heritage Site.

Ashikaga Yoshimasa (足利義政 )
After Ashikaga Yoshimitsu (足利義満 ) died (49 years old), the Muromachi Bakufu became financially weaker that made the military power weaker. As a result, Daimyo (feudal lord) became powerful. A few generations after Shogun Yoshimitsu, Ashikaga Yohimasa became a Shogun (8th Ashikaga Shogun). His wife is the famous Hino Tomiko (refer 21|Muromachi Period History （室町時代. It is said that Shogun Yoshimasa was not interested in his job as a Shogun, but he was a great culture person who influenced the base of today’s Japanese art, such as Japanese garden, Shoin Zukuri (書院造り)*, Tea ceremony, Flower Arrangement, Painting, and other art forms. His cultural attribute is called Higashiyama Bunka (Higashiyama culture (東山文化). As it is described in Chapter, 21|Muromachi Period History （室町時代, Shogun Yoshimasa did not have a child, his brother Yoshimi (義視) was supposed to be a next Shogun. But his wife, Hino Tomiko gave birth to a son, Yoshihisa (義尚 ). Hino Tomiko asked Yamana Sozen (powerful family 山名宗全 ) to back up her son, and brother Yoshimi joined with Hosokawa Katsumoto (powerful family 細川勝元). The problem was Shogun Yoshimasa was paying attention too much to all his cultural hobbies, did not pay attention to the problem he created by not being clear who should be the next Shogun. He did not yield Shogunate to either one. He kept enjoying his cultural hobby. In 1467, on top of the successor problem, because of the other conflict of interest of other powerful Daimyo, “Onin-no-Run (応仁の乱 ) started. All the Daimyo sided either Hosokawa group or Yamana group. Eventually, the war spread to the rest of Japan and last over 10 years. Finally at 1477, after both Hosokawa Katsumono and Yamana Sozen died, Shogun Yoshimasa decided to transfer Shogunate to his son Yoshihisa. This war caused Kyoto to be devastated and weakened the power of Ashikaga Bakufu. While all this is happening, people were suffering from the war, Yoshimasa still spent money to build Ginnkakuji Temple (silver Pavillion, 銀閣寺 ). He died without seeing the completion of Ginkakuji temple. Onin-no-Run will lead to the next Sengoku-Jidai (100-year warring States period).

The characteristic of the picture above, the shape is emphasized in the drawing.
At the end of chapter 20 | Nanboku-Cho Tanto（南北朝短刀, there is a list of swordsmith’s names. Hiromitsu and Akihiro represent the most common characteristic of Nanboku-Cho Tanto.
Hiromitsu From Sano Museum Catalogue (permission granted)
Enbun Jyoji Ko-wakizashi Tanto is also called Sun-Nobi Tanto. The top part of the Tanto bends outward slightly, this is called Sakizori.
Hiromitu and Akihiro Characteristic

Nakago ——-Tanago-Bara shape (refer 20 | Nanboku-Cho Tanto（南北朝短刀).
The first generation Shodai Nobukuni is the top three students of Sadamune. He is called Sadamune San Tetsu (貞宗三哲). The characteristic of Nobukuni is almost the same as the characteristic of Hiromitsu and Akihiro. Nobukuni also created Sun-nobi Tanto like the one below which has a Hoso-suguha (narrow straight tempered line), Ko-Mokume (fine small burl), Ko-maru Boshi (small round)

This chapter is more detailed part of Chapter 19. Please read Chapter 19 before this chapter.
The drawing below is the illustration from chapter 19. Compare this illustration and the photos underneath of it. It shows the similarity of the shape. Keep in mind this illustration is the shape of a very long sword that was shortened at a later time. At Nanboku-Cho time, swords smiths created 3, 4, 5 feet long swords. Later shortened to 2.5 feet or so.

“Chogi” from Sano Museum Catalogue (permission granted)
Characteristic of Chogi (長義）
Shape ——— Originally very long. Shortened to approximately around 2.5 feet.
Hamon ——–Wide showy tempered line. Basically Nioi, but Nie shows a lot. Sunagashi (砂流し) appears. Notare (wavy) mixed with Gunome. Sometimes Chogi’s created one pair of ear robe shape called Chogi’s earlobe shape midare.
Boshi ——— Irregular Midare and sharp turn back Ji–Hada ——- Itame ( a wood grain)
Aoe from Sano Museum Catalogue (Permission granted)
Aoe is pronounced “A” as apple, “o” as original, and “e” as edge. Aoe is a swordsmith from Bittchu province that is next to Bizen. Therefore the characteristic of the sword, Ko-Aoe, and Ko-Bizen are similar.
From middle Kamakura period to Nanboku-Cho period was the best time for Aoe group.
Characteristic of Aoe (青江)
Aoe sword has Aoe-Zori shape that is to curve a lot at the lower part. During Nanboku-Cho time, because of the Soshu-Den was the trendy style, even Bizen sword smiths did Nie. Yet, Bittchu stayed Nioi. The tempered area tends to be wide. Sakasa-Choji (means inverted or backward, see the illustration above) is the Aoe’s most notable characteristic. Also, Boshi often has pointed hamon. It is often said that if you see sakasa-choji, it should be either Aoe group or Katayama Ichimonji group. Sumitetu (澄鉄 black Jigane from the inside shows through) is also Aoe’s characteristic.
I was in Japan earlier this May. Here is the Tombstone of Masamune (正宗) in Honkakuji Temple (本覚寺) and Masamune kogei store in Kamakura . This store is owned by Tsunahiro Yamamura who is the 24th generation of Masamune.
Here is the map of Kamakura that shows the location of the Honkakuji Temple (circle) and Masamune Kogei store marked the circle with X in it.
This map is from Kamakura station information center.

Chapter 52 is the continued part of chapter 17 Late Kamakura period Tanto (17 | Late Kamakura period Tanto ——- Early Soshu-Den Tanto. Please read Chapter 17 before chapter 52.
After studying the general common characteristics of the late Kamakura period Tanto style (that is early Soshu-Den Tanto) on chapter 17, what points do the next two swords fit in with the common characteristic of early Soshu-Den Tanto?
Goro Nyudo Masamune (相州伝五郎入道正宗) from Sano Museum Catalog (permission granted).
Masamune was born in Kamakura as a son of Tosaburo Yukimitu. Masamune is a very well-known sword smith even among those who are not interested in a sword. His tombstone is in Honkaku-Ji (本覚寺) temple near Kamakura train station, approximately 6 minutes’ walk from the station.
Characteristic—– Hira zukuri. Very slightly sakizori (tip area curves slightly outward). Bo-hi and Tsure-hi. Boshi is Ko-maru. Hamon is Notare (wavy). From the illustration above, Sunagashi, Nijyuu-ba can be seen. One of the important characteristics to connosseur sword is Nie or Nioi and Ji-hada. It is not possible to see it from this photo, but Masamune does Nie and usually wood grain surface. Nie is the Soshu-Den characteristic. This type of Nakago is called Tanago-bara. Masamune Tanto is often Mu–Mei (no signature).
Higo Province Enju Kunisuke From Sano Museum Catalogu (permission granted)
Enju group lived at Kikuchi county in Higo Province (Kyushu). The characteristic of Enju group is very similar to the one of Yamashiro style. Because Enju Kunimura who started the Enju group was said to be the son-in-law of Rai Kuniyuki of Yamashiro-Den.
Characteristic—-Hamon is Hoso Suguha (straight temper line). Boshi is Ko-maru. Front engraving is Suken (left photo of the sword) and the engraving on the back is Gomabashi ( right photo of the sword). Jitetsu or Jihada is tight Itame. Nie
This chapter is the continued part of chapter 16|The Revival of Yamato Den （大和伝復活 . Please read chapter 16 before reading this chapter.
At the end of the Kamakura period, in the Yamato area, powerful temples expanded their territory. They had the political and military power to control the area. Especially a few powerful temples owned a large territory. They were called Shoen (荘園). The demand for the Sword increased by warrior monks called Sohei (僧兵). That started the revival of Yamato school. Some of the big temples had their own swordsmiths within their territory. Todaiji-temple (東大寺) backed Tegai (手掻 ) group. Senjuin (千手院 ) group lived near Senju-Do (千手堂 ) where Senju Kannon (千手観音 ) was enshrined. The name of the Taima group came from Taima-Ji temple (当麻寺). Shikkake group (尻懸 ) and Hosho group (保昌 ) as well. Those five groups are called Yamato Goha (Yamato five groups).
General Characteristic of Yamato Den
Yamato Den (大和伝) sword always shows Masame (柾目, straight grain like) on somewhere on Ji-Hada, Jigane or Hamon. Please refer to the 16 Revival of Yamato Den (大和伝復活) for its general characteristic. Masame is sometimes mixed with Mokume (burl like) or Itame (wood grain like). Either way, Yamato sword shows Masame somewhere. Some sword shows Masame entirely or some shows a lesser amount. Because of that, Hamon tends to show Sunagashi (brush stroke like) or a double line like Hamon called Nijyu-ha.

Example of Kantei process how to figure out the maker of the sword using the above photo
By looking at the bold letter above, analyzing the above information, you conclude and come up with the name of the swordsmith. In reality, to Kantei, bring more checkpoints and come up the name.
This is my Japanese room. The right side of the Yoroi ( armor) is Saya (scabbard) made by Yoshindo Yoshihara (吉原義人). I will have a picture or video of the sword made by him in the future post.
This chapter is the detailed part of chapter 15| Late Kamakura Period Sword. Please read chapter 15 before this section.
As I explained in chapter 14 Late Kamakura Period History (鎌倉後期), Ikubi Kissaki sword shows a flaw (above illustration) when the damaged area was repaired. To compensate for this flaw, in Late Kamakura Period, swords smiths started to forge swords with longer Kissaki and a tip of Hi ends lower than Yokote-line. So that in case the Yokote-line was lowered after the repair, Hi does not go higher than Yokote-line
Above photo is Goro Nyudo Masamune( 五郎入道正宗 ). Please look at the size and shape of Kissaki. This is definitely different than previous Ikubi Kissaki, or Ko-Gissaki. This is a typical late Kamakura period Kissaki style. This is O-Suriage (largely shortened). Under Kamakura Bakufu, many swordsmiths moved to Kamakura. They were Toroku Sakon Kunituna (藤六左近国綱 ) of Yamashiro Awataguchi group(山城粟田口), Fukuoka Ichimonji Sukezane (福岡一文字助真) and Kunimune (国宗 )of Bizen area. They are the origin of Soshu-Den (相州伝). Eventually, Tosaburo Yukimitsu (藤三郎行光) appeared and his son is the famous Masamune (正宗). On the illustration above, Kinsuji, Inazuma is shown inside the Hamon. The clear line inside the Hamon is Inazuma and Kinsuji. Kinsuji, Inazuma are the collection of Nie looks like a line. Masamune is famous for Inazuma, Kinsuji. Masamune lived in Kamakura, his Hamon looks like an ocean wave when it is viewed sideways.
The above picture is Yoshioka Ichimonji (吉岡一文字). Kissaki is also like the one of Masamune. It is longer than previous Ikubi Kissaki or Ko-Gissaki. This is Chu-Gissaki. Kissaki like this is the important point to determine what period the sword was made. Hamon has Choji, Gunome, Togariba (pointed tip), very tight Nie.
Above photo is Ukai Unsho (鵜飼雲生). This is also the sword from the late Kamakura period. But it has Ko-Gissaki. This sword does not have the late Kamakura period Chu-Gissaki style. Narrow Hoso-Suguha is somewhat like earlier time than the late Kamakura period. I chose this sword here to show that the sword does not always have the style of that period. To Kantei*, first, look at the style and shape and give yourself some idea of the period of the time you think it was made. But in this case, Kissaki does not indicate late Kamakura period. Next thing to do is to look at the different characteristic of the sword one by one like Hamon, Nie or Nioi, Jihada, etc, and determine what period, which Den, which province and finally come up with a swordsmith’s name. This process is called Kantei.
*Kantei – – – – – – to determine the name of the swordsmith by looking at the characteristic of the sword without looking at the Mei (inscription). Mei is not always there either because it is shortened or some other reasons.

Genko (元寇) — Mongolian Invasion
In Chapter 14, the Mongolian invasion was simply described. Here is the more detailed description. The Mongol Empire was a vast empire spread between present Mongol areas to all the way to Eastern Europe from 1206 to 1368. Grandson of Genghis Kahn, Kublai Kahn sent several official letters to Japan demanding Japan to become a dependency state of the Mongol Empire (Yuan) and demanded to send a tribute to them. They threatened Japan that they will invade if Japan did not accept their demand. Hojo Tokimune (北条時宗 ) who was in power in Kamakura Bakufu (government) then, refused and ignored the letters many times. That caused the two times invasions by the Mongol Empire. The prevailing notion is that the strong typhoon hit Japan on each invasion, Mongols were chased away by the typhoon. There were more to it to the story.
Bunnei-no-Eki (文永の役 ) 1274
The first Mongolian invasion is called Bunnei-no-Eki. The early part of October 1274, 40,000 Mongol troops (Mongol, Han people, and Korean) departed heading to Japan from Korean peninsula on 900 large and small ships. After they arrived on the Tsushima island (対馬 ), Mongol troop burnt villages and killed many people including the island people. Many people were captured and presented to the top officials of the Mongols as their slaves. It was a really miserable sad scene. The Mongols moved to Iki Island (壱岐の島), then to Hizen shore (肥前 ), Hirato Island (平戸 ), Taka-Shima (鷹島 ), then to Hakata bay (博多). At each place, the disastrous scene was the same as everywhere. At each battlefield, Japanese soldiers and villagers were killed in great numbers. Kamakura Bukufu (government) sent many Samurai to the battlefield, the Japanese side won and pushed the Mongols back here and there but mostly Japanese sides lost. Many wives and children were captured, eventually, even no soldiers dared to fight against Mongols. Mongols arrows were short and not so powerful, but they put on the poison at the tip, and they shoot the arrows like rain. Also, this is the first time the Japanese saw the firearms. Their loud sound of the explosion made horses and Samurai frightened. Japanese troops had to retreat and the situation was really bad for Japanese. But all of a sudden surprisingly, on morning of the of October 21st (today’s calendar, Nov 19th) all the ships were gone, nowhere to be seen on the shore. Mongols were all disappeared from the shore of Hakata. What happened was Mongols decided to quit the fight and went back. For Mongols, even though they were winning, they also lost many people and lost one of the major key person in the army. The different history book of Korea and Mongols had several records about the reasons to leave Japan. The Mongols realized no matter how Mongols were winning, the Japanese kept coming more and more from everywhere. The Mongols could not expect reinforcements from their country over the ocean. Also, their stocks of weapons were getting low. It was the Mongols decision to go back. Here is a twist. Around the end of October (November by the today’s calendar), the sea between Hakata (where Mongols were) and Korea was very dangerous because of the bad weather, unless the clear daytime of south wind day. This place is called Genkai Nada (玄界灘 ) famous for the rough sea. Yet Mongols decided to go back at night. They may have caught the moment of the south wind, but it did not last long. As a result, they encountered the usual severe rainstorm. Many ships hit against the cliff, ships capsized, people fell into the ocean, and several hundred broken ships were found on the shore. This is called Bunnei- no- Eki (文永の役 ). Mongols lost a large number of people, ships, troop, food, weapons, and Korea who was forced to supply all of them by the Mongols lost a great deal. Only old men and children were left to work on the farm, on top of it, they had drought and long rain.
At this Bunnei-no-Eki (文永の役), it was not a typhoon that caused the Mongols to be defeated, Mongols decided to leave but encountered usual bad weather.
Koan-no-Eki (弘安の役) 1281
The second Mongolian invasion is called Koan-no-Eki in 1281. After the first attempt to invade Japan, Kublai Khan kept sending messengers to Japan to demand to become a dependency state. Kamakura Bakufu kept ignoring and they killed messengers. Kublai Kahn decided to attack Japan again in 1281. Kublai Kahn’s top advisers suggested not to attack Japan because it is too far, the ocean is too dangerous, the country is small, and nothing to gain even if Mongols win. But Kublai Kahn still insisted to attack. This time they came in two groups. They were the East-route troop, the number was 60,000 soldiers on 900 ships, and the South-route troop, the number was 100,000 soldiers on 3,500 ships. This is the largest scale forces in history. Their plan was to depart from each one’s port and join on the Iki-no-Shima island (壱岐の島 ) by June 15th, then work together. The East-route troop arrived before the South-route troop came. Instead of waiting for the South-route troop, the East-route troop started to attack the Hakata Bay (博多) on their own. But by that time, Japan already prepared to fight and built a 20 kilometer long stone wall. This stone wall was 3 meters high and 2 meters thick. The East-route troop had to give up to land on Japan from Hakata and moved to Shiga-no-Shima (志賀島 ). At this place, the fight between Mongols and Japan was even battle but at the end, East-route troop lost and retreated to the Iki-no-Shima and decided to wait for the South-route troop to arrive. The South troop never arrived there, they changed the plan. On top of that, while they were waiting for the South-route troop to come, they lost over 3,000 men over the epidemic. With difficulty like this, the East- route troop discussed the choices they can take. One opinion was going back home but in the end, they decided to wait for the South-rout troop to arrive as long as the food last. Meantime, the South-route troop changed the plan and decided to go to Hirato-Shima (平戸島 ) where it is closer to Dazaifu (太宰府). That is the final and most important place they wanted to attack. Later, the East-route troop found out the South-route troop went to Hirato Shima. Finally, two troops joined at Hirato-Shima and each group stationed nearby island called Taka-shima (鷹島 ). The problem was this island had very high tide and low tide, the ships were not easily maneuvered. Meantime, 60,000 Japanese men were marching toward where the Mongols were stationed. Before those men arrived to fight against Mongols, A big typhoon came on July 30th and Mongols were caught in a big typhoon, ships hitting each other, people fell from the ships and drowned and the majority of ships sank. July 30th was about three months after the East- route troop left Mongol on early May. That means they were on the ocean and the shore of Japan for about three months or so. Around North Kyushu area (九州 ), usually, a typhoon comes average 3.2 times between the month of July to September. Mongols were on the ocean and the shorelines of Japan for approximately three months; they were bound to be hit by a typhoon soon or later.
The Mongol Empire lost 2/3 of its naval forces. After Mongols failed two attempts to attack Japan, Kublai Khan still insisted to attack Japan the third time, no matter how much his men reasoned him. But the plan was delayed and terminated because of many rebellions, upheavals and no lumber was left to build ships. Soon, Kublai died in 1294. The record book of Mongols and Korean indicated that Mongols officials gave a high evaluation of Japanese swords. Some even say one of the reasons it was not easy to defeat Japan was because of the long sharp swords. The experience of the Mongolian invasion changed Ikubi Kissaki (猪首切先) sword to a new Soshu-Den (相州伝) style sword.
