The streets of Tokyo are left without names. Indeed there are written addresses used by the mail carriers and the big avenues have got names. But those are not visible signs in the urban structure and therefore not usable. The fuzziness in the identification makes the way finding a bit uneasy.

Therefore all locations have in addition to the written address an information based on the relation to the next subway station and a certain exit. For instant: 11 minutes walk from Exit B2 at Kiyosumi-Shirakawa Station on the Hanzomon Line.
