Legendary Tenshodo /大勝堂; Taishōdō/ got its start as a shop selling name seals and stamps located in Ginza, Tokyo in 1879. Soon after opening it set to ventures designed to satisfy stylish customers, such as establishing a show window and expanding into the import and sales of watches, diamonds, precious metals and railroad models. Shop is still active today https://www.tenshodo.co.jp/.
