>>212587408On my first trip I was just in Tokyo. Back in December 2017. It was fun, spent two weeks exploring the city. Even got some snow which was cool.
Second trip was south down to the islands, Okinawa, Yakushima and some other places plus Nagasaki. Way different vibe down there but it was August and the temp pushed 35+ almost daily so be aware.
This time I am going back to Tokyo for a week, then one week each in Kyoto and Fukuoka.
I highly recommend taking flights/trains across the country and not just staying in one city.
