Heading over on Sunday for 3 weeks - can't wait and the weather looks favourable heading into sakura season.
The trip is bookended with stints in Tokyo (Shibuya and Ginza) but we're also going to Lake Kawaguchiko, Hakone, Magome (as per a recommendation I read in here), Kyoto, Kobe and Osaka - most likely a day-trip to Nara at some point too.
I enjoyed Hakone, take advantage of the free pass. Hopefully you get a clear day and can see Fuji from Lake Ashi
