Day 1: tsukiji fish market -- ginza -- shibuya --- odaiba onsen

Day 2: (shibuya --if missing something on the frist day)-- shinjuku -- shiodome

Day 3 (Sunday): harajuku --aoyama -- ebisu -- roppongi

Day 4: akihabara -- asakusa -- ueno -- shinjuku (night life)

Day 5: ikebukuro--???(somewhere else if there is time) --airport (plane leaves at 7pm)

Please comment on my itinerary and suggest how to make it better. Thanks you.

It certainly depends on what you intend to do while in Tokyo and what your interests are. Have you considered day trips, perhaps to Nikko, Kamakura or Hakone?

Hi,
Thanks for the reply. Actually I would have already been to kamakura and nikko, kyoto, osaka and koyasan before arriving back to tokyo for the 5 days. So i want to see if the plan is realistic enough to see all the parts of tokyo i am interested in.
Thanks.
