No. 36.

Type: Shinto katana

 

Nagasa: 64.7 cm     Moto-haba: 2.9 cm  Saki-haba: 2.1 cm

 Sugata:         Shinogi-zukuri, iori-mune, shallow tori-zori, small chu-kissaki

Hamon:         Nioi-deki, a wide choji-gunome-midare, often reaching the shinogi but becoming quieter in the monouchi area, some tobiyaki. Many ashi, including saki-ashi (sloping) and ko-ashi as well as a few yo. The boshi on the ura is slightly notare ending in ko-maru with kaeri, the omote is similar but slightly “deformed”.

  Jihada:          Difficult to see but appears to be a very tight ko-mokume. Occasional utsuri visible along the shinogi.

  Nakago:        Suriage and machi-okuri by 10.5 cm, kiri-jiri. 2 mekugi ana, the original plugged with silver. O-sujikai yasurime on the original part of the nakago and kiri on the newer section. Signed on the omote: BITCHU (no) KAMI TACHIBANA YASUHIRO and a 16 petal kiku engraved on the ura.

The nioi-deki hamon in choji-midare, together with the faint glimpses of utsuri near the shinogi, indicate Bizen as the inspirational style of this sword. It is particularly important to appreciate and note the shape of this blade, which although altered by machi-okuri, is still unmistakably that of the Kanbun-shinto period (1660-1673). This easily leads one away from the mistaken conclusion that it may be an old Ichimonji sword. A further indication would have been the presence of a yakidashi in the moto-haba region, but this has been lost by the machi-okuri. The main practitioners of  Bizen-den in the Kanbun-shinto period were the so-called Ishido school and so this sword would represent a reasonably easy “dozen” in kantei, if your vote were cast to one of the swordsmiths of the Ishido school. Apart from ashi, there are relatively few hataraki in the hamon.

A group of swordsmiths, originally from Omi province, claimed descent from the Ichimonji school and strove to replicate the Bizen Ichimonji style. In the early shinto period, they founded the Ishido school at Wakayama in Kii province, as well as prosperous branches at Edo and Fukuoka in Chikuzen province. The leader and founder of the Wakayama group (known as the Kisshi Ishido) was Mutsu (no) Kami Tameyasu and he had two sons. The elder, whose personal name  was Hatakeda Rokurozaemon had the same art name and title as his father, whilst the younger brother, Tomita Gorozaemon was Bitchu (no) Kami Tachibana Yasuhiro. They moved to Osaka in Settsu province and started the Osaka Ishido school there, indeed, Yasuhiro is credited by some sources, as being the actual founder of Osaka Ishido. There are examples of his work made whilst he was still in Kii province as well as later examples from Osaka, he also lived in Kyoto for a while. The Kiku carved on the ura is an unusual feature of Yasuhiro’s mei.

Three generations with the same name and title succeeded the shodai. The shodai Yasuhiro is rated as Chujosaku by Fujishiro who also classes his blades as “wazamono”.

This sword has no modern Japanese papers of authentication. It has previously only appeared in a To-ken Programme in printed form and is updated here for inclusion on this website.
