Harvest. I did what your plans are two years ago virtually. Loved it. Stayed in Shibuya for for 5 days. Great place. Then went to Hakone for a couple of days. it was OK, but a bit quiet TBH. From there we we went on Lake Kamaguchi to see Fuji. Great views. Then went back to Tokyo and got the Shikansen to Kyoto, which we which we used as a base. TBH I would have preferred to use Osaka as the base. I was only there for a day, but that place is a blast.
Then back on the Shikansen back to Tokyo got the last couple of days where I think we stayed in Kotor City. It was like the Toyko equivalent of Canary Wharf. The missus and I were there for two and a half weeks, but I wish I went for a month.
