We found it not too hard to find the prices and just used google conversion to convert Yen to $.

On a side note, we were planning on going in 2020 but since the Olympics were scheduled, the hotel prices were INSANE!! So, we had made plans to go in 2021. Then the Olympics were moved to 2021 because of the pandemic. We are now planning on 2022, where hopefully the prices will return to normal.
