I'm landing in Tokyo first and stay 5 days there, then I'm taking the bus to kyoto. I'll stay three days there and I'll travel by bus to Osaka and stay other three days. I'll finally take the bus to Hiroshima and stay two days (one spent in myiajima island). I'll then take again the bus and come back to Tokyo to fly back to London the next day.

The budget per person is £730, including flight, accomodation and bus travel.
