One-day bus trip to Kamikochi Nagano
We left Tokyo at7:00, got there around 11:30, stayed there for 3 hours. It was quite cheap for us, paid about 5000yen per person.
Another option was that you leave Tokyo late night, and get there early morning. But it would cost more and sounds exhausting.
So it was better off spending extra-money for more foods.
we decided to come back on the same day.
