Both Shibuya and Shimo-Kitazawa have several 'live houses' (small to medium-sized concert venues). Shimokita's tend to be intimate and underground, though there are some of these in Shibuya, too. Shimo-Kitazawa is also the centre of Tokyo's fringe theatre scene – though this can be hard to break into without a solid grasp of Japanese.
Feature: Getting Tickets
Ticket Pia is the source for concert and theatre tickets; there are kiosks located on the ground floor of Tower Records and on the 2nd floor of Shibuya 109. Staff may not speak English but if you write down the name and date of the event, they can usually manage. Note that some venues stop selling advanced tickets one to three days before the show.
