With multiple small showrooms spread out over two rather compact floors, Makii Masuru is a bit more spacious than most of the galleries in the area, and hosts some interesting group shows of international artists. They're located just north of the main Bakurocho gallery area, but worth a small detour to check out.

As with any small gallery, you might want to check their website first to see if there's anything currently showing. They have slightly earlier closing times on the last day of each show.
