Taikei Naotane (大慶直胤)

One of the three great smiths of Edo of shinshintō and the workshop his son-in-law inherited: his life, his way of forging Bizen and Sōshū, his designated works and his sources

According to the NBTHK, Naotane was the most outstanding pupil of Suishinshi Masahide. He is one of the Edo sansaku (江戸三作), the three great swordsmiths of Edo of shinshintō, with Masahide and Minamoto Kiyomaro. For more than fifty years he forged faithful copies of the old masters of Bizen and Sagami, and his workshop was inherited by his son-in-law, Jirōtarō Naokatsu.

His blades, the titles in his signature and his place in the school are documented by the NBTHK and by museums. His date of birth and the dates of his early years vary from source to source.

In short

What we know. That, according to the NBTHK, he was a pupil of Suishinshi Masahide and his works surpass Masahide’s: he forged Bizen copies in the style of Kagemitsu and Kanemitsu and Sōshū blades, and signed with his titles of Chikuzen Daijō and Mino no Suke. He has blades designated Important Art Object (重要美術品, Jūyō Bijutsuhin) and cultural properties of Okayama and Mie prefectures, and the Tokyo National Museum and the Metropolitan in New York hold works of his.

How we know it. From the NBTHK’s commentaries in its Sword Journal and in the labels of the 2025 Edo sansaku exhibition, and from the records of the museums and the prefectures. His life is told in detail by the researcher Markus Sesko and by the Japanese Wikipedia.

What we do not know. Whether he was born in 1778 or in 1779, whether he became independent in 1801 or around 1804, and whether he entered the service of the Akimoto in 1811 or in 1812: the sources disagree. It is not recorded in the sources consulted that he appears in the Yamada cutting lists.
