Here is 3 big good points from past users.
1. best place for 1-2 users. you can be satisfied with Japan with relaxed atmosphere
2. good access to IKEBUKURO and SHINJUKU which are very famous places in Japan. you can visit Roppongi, Tsukiji, or Asakusa use only one train line.
3. many comics I recommend! all of comics are not published in any other countries. there are various genres like action, love, SF stories.
Why not make your visit to Japan more wonderful??
Shiinamachi station is famous for Izakaya.
If you like alchole
