Source-derived summary

Oishi Susumu Tanetsugu (大石進種次, 1798–1863) was a Japanese kenjutsu practitioner. He was active during the Tenpō period in the first half of the nineteenth century. A retainer of the Tachibana clan, he was unusually tall for a Japanese person of his day, standing 7 ft (210 cm) tall.

Having trained in the Yagyū Shinkage-ryū, Oishi started his own style of swordsmanship called the Oishi Shinkage Ryu, which attracted many pupils and made Oishi comparatively wealthy. He also made money from dojo arashi (dojo storming), a practice in which a skilled swordsman would challenge masters of other schools. As Oishi was a formidable fighter, many teachers paid him off in order to avoid the embarrassment of a public defeat. Oishi himself eventually suffered a swift and humiliating defeat at the hands of Otani Nobutomo, a swordsman of the Jikishinkage-ryū.

He specialised in powerful thrusting techniques, which were made more effective by the length of his weapon. At the time there was no standardisation of equipment in kendo, and Oishi was noted for using exceptionally long swords or shinai (practice swords), sometimes with blades as long as 5 ft 3 in (1.60 meters). He also made use of customised bōgu (kendo armour), adding complex deflective crests and flaps to confound an opponent's attacks.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as japanese kenjutsu practitioner (1798–1863). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Oct 28, 2025. The linked authority identifier is Q11438247. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1798 and 1863.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
