I planned my arrival in Tokyo for Memorial Day Weekend to give me an extra day off to get over my jet lag.  I also booked a 9am walking tour of the more popular attractions close to my neighborhood.  This way I could get my bearings on the area before diving headlong into work.  Some of the highlights included Shibuya Crossing, Tsujiki Fish Market, Hongan-ji Temple, and Senso-ji Temple.
