【Description】
Summary
This blade was signed by Shimada Sukemune(島田助宗). Sukemune belonged to Shimada school in the Suruga domain(today’s Shizuoka prefecture). Its foundation dates back to the mid-Muromachi period, and it was founded by Yoshisuke(義助). The first-gen Sukemune was the younger brother of Yoshisuke.
The swordsmith’s name Sukeume lasted four generations, and they were active in sword-forging during the Tenbun-Kanbun era(1532-1673). We believe this blade was signed by an early generation of Sukemune, who was active during the late Muromachi period.
The first-gen Yoshisuke served a powerful feudal family named Imagawa. It is said that he received his maker’s name 義 from Imagawa Yoshitada. Shimada school interacted with other schools in Soshu swordsmiths living near Odawa castle in Kanagawa prefecture. The Suruga domain was vital for strong feudal lords such as Takeda, Tokugawa, and Hojo clan during the Sengoku Jidai (Warring state period). The swordsmiths in Shimada school received many orders from these strong feudal families.
Soshu Den
It is said that the generations of Sukemune mastered a particular sword-forging tradition called Soshu Den. Shoshu Den was born in the middle of the Kamakura period. Back then, the Yamato and Yamashiro traditions were highly developed, and there were a few renowned swordsmiths from those regions. However, the sword-forging practice was in its infancy in the Kanto area, where the Soshu region was located.
At the beginning of the Kamakura government, which was established in 1185, the first Shogun, Minamoto Yoritomo, prioritized making a lot of rules to have its political stability. And he couldn’t afford to hire swordsmiths within the same region or train them. Therefore, the Kamakura government originally ordered weapons to the swordsmiths in the other areas, such as Yamato and Yamashiro.
But, since the government was established, the demand for weapons increased exponentially in the government, and they had to figure out how to meet those demands from Samurai who served Kamakura shogunate. Then, the 5th head of the Shogun, Hojo Tokiyori, invited two renowned swordsmiths from other parts of Japan. They were Awataguchi Kunitsuna from Yamashiro province and Bizen Saburo Kunimune from Bizen province. And the 7th-gen Shogun Koreyasu Shino also invited Fukuoka Ichimonji Sukezane from Bizen province.
It is said that those three swordsmiths played an essential role in creating the Soshu Den and making the foundation of the Soshu Den. Also another famous figure in the Soshu den is Intou Kunimitsu, an adopted son of Awataguchi Knitsuna. And Kunimitsu passed his excellent craftsmanship to Yukimitsu, his apprentice. And Masamune, one of the most famous swordsmiths in Japanese history, was an apprentice of Yukimitsu. And Masamune was the one that brought Shoshuden to nationwide fame. The tradition Masamune completed became an example of other swordsmiths who learned Soshu Den. Also, Soshu Den influenced many renowned swordsmiths during the Koto- Shinto era. One of examples is Inoue Shinkai from Osaka and Suishinshi Masahide from Edo.
What is Tanto?
It was initially used as a supplemental weapon for Samurai on horseback, who used a pole weapon or long sword in the Kamaura-Muromachi period. Samurai aimed at an unprotected area of his enemy’s armor with Tanto while having to fight with close distance.
TANTO was named accordingly, depending on how you carry it, such as HUTOKORO-GATANA (懐刀; Stomach-Sword) or KOSHI-GATANA(腰刀; Waist-Sword) or elsewise. TANTO was also a gift for a bride from her family in a traditional Japanese wedding, as it is believed that TANTO would be divine protection from evil power.
