He runs Kourindou, an antiques shop near the Forest of Magic stocked with items found in the human world outside Gensokyo, sometimes supplied by Yukari. Reimu and Marisa often visit him, but rarely as customers.
He recently got a small robot dog pet, which he named Laika.
Doujinshi sometimes portray him either as a lecherous pervert running around wearing only a fundoshi or as an extremely muscular male with power almost equal to the rest of the cast - dubbed MANnosuke.
He makes a cameo in the background of the Human Village stage in Hopeless Masquerade, his first official in-game appearance of any kind.
