[Tsukikage]

i think the trip to Kyoto takes about 3 hours on the buller train, well worth a visit! altough you cant do it in a day, i was there for about a week, enjoyed every second of it!
hiroshima (mable further than 3 hours, nearer 5-6 i think,) on the other hand can be done in a day im sorry to say

North of Tokyo, you could go to Nikko, (about an hour away i think) they have golden roofed temples up there and its a beautiful place to be
