How much money do you need per person in Japan?
One hundred per day
500k, if you buy less clothes and souvenirs, then 300
Spent 160K on tickets from Moscow (back to Tokyo - Beijing), accommodation, and other expenses (food (including restaurants), souvenirs, transportation, additional excursions like the Ashinoko boat, and so on) for 2 weeks)
If I had known the transportation nuances and arranged the logistics better, it would have been cheaper
I will also add that I traveled to Tokyo and its suburbs, Kyoto, Osaka, Nara, and Kyoto's suburbs
