At Shinjuku for meetings in the evening followed by a quick photo walk. Shinjuku used to be my hub when we first moved to Tokyo - we lived in Higashi Fushimi on the Seibu Shinjuku line which came into Shinjuku.
Hardly visit Shinjuku these days but when I do it always brings back nostalgic memories of the early days which you may have read in the Tokyo 1999 - 2001 and Tokyo 2001 - 2004 post.
