no Kami Tachibana Yasuhiro, whose personal name was Tomita Gorozaemon, was a representative master of the Kishu Ishido group. He later moved from Kishu to Osaka and became the founder of the Osaka Ishido lineage, active around the era (1661-1673). His workmanship follows what the assessors term the "hereditary specialty of the school": the tradition, with a forging pattern in which is clearly expressed, and tempering as his particular forte. In his earlier period he signed as " no Yasuhiro" or with the "Toichi" prefix; after receiving his court title, he sometimes divided his inscription between and and carved a chrysanthemum crest on the reverse.
His characteristic forging is a tightly packed in which stands out prominently, serving as the foundation for his tempering. The is typically mixed with juka- (layered-flower style), , , and , with and entering vigorously to produce an exceptionally florid, brilliant effect; the work is -dominant with a bright . Some works exhibit a (reverse-slant tendency), which the assessors identify as a trait of his early, youthful production phase. In a notable departure, one designated centers on large in a so-called kawari- (unusual style) with deep and well-adhering , revealing a connection with Yamato no Kami Yasusada, with whom Yasuhiro is known to have collaborated.
His designated works include blades in the Imperial Collection and pieces formerly transmitted in the Shimazu house of Satsuma Province. Across these, the assessors repeatedly note that his finest and display an unusually rich spirit and force, with height variation in the tempered edge that elevates his beyond merely small patterns into something genuinely flamboyant. The rare example in the collection further demonstrates his range within the Ishido tradition.
