Osakaya was founded in 1630. The first generation, who was a vassal of the Toyotomi family, was defeated by the Tokugawa family in the Osaka Winter and Summer Campaigns, and after the Toyotomi family fell to the Tokugawa family, he arrived in Hirosaki through his family connections and founded Osakaya, serving as the confectioner for the Tsugaru domain lord.
The "Takenagashi" is a famous confectionary representing Osakaya, and was created 240 years ago by the fourth generation of the family, inspired by a gold sheet poured into bamboo and hardened at the Oppu Mine in Nakatsugaru-gun. The simple confectionery, made of only flour, sugar, and buckwheat flour, cannot be made by machine and is still made by hand with a lot of time and effort. Each one has a different shape, and you will find yourself eating more than you expected because you can enjoy the various textures, such as loose, crispy, and tender.
You can purchase them at the Nihonbashi Takashimaya's famous sweets shop, so why not visit the Ginza showroom when you stop by? At Osakaya in Aomori, the confections are still sold in chests decorated with peonies (mother-of-pearl inlay), the family crest of the Tsugaru family, so I would like to visit the store someday to see them.
