Genius was one of Shibuya's more famous jazz cafes for more than 20 years before increasing rents pushed them out, necessitating a move to sleepy Nakano-Shinbashi, a bit west of Shinjuku.
It is owned and operated by the lovely Suzuki-family, a warm and chatty couple with many jazz stories in their past. The cafe is filled with beautiful black & white photos taken at gigs over the years, as well as a substantial collection of Japanese jazz magazines and journals. The main attraction at Genius though is the huge record collection; Suzuki-san humbly claimed it was only 'a couple thousand, with some more at home' but there's certainly more than that. By my eye test I'd guess 5000+, and word from some customers is that they have another 5000 at home, rotating what they bring to the cafe. When I was last there he pulled out an amazing John Coltrane in Europe bootleg featuring Eric Dolphy, an absolute treasure.
The sound system is pristine and there is tasty cake and coffee on the menu, plus the usual alcohol options. Genius is yet another perfect spot to spend an afternoon listening to jazz. Pictures of Genius are over at Tokyo Jazz Joints.
