you could live your whole life in tokyo and still not see it all.
it's a bit like the golden gate bridge.
by the time you're done, you need to start over.
but if you go see the rest of the country.
wow.
this photo is from fukuoka.
it's in the west of japan.
highly recommended.
all of the neighbourhoods are connected so you don't get those boring parts in between districts where nothing is happening.
it makes the city feel much bigger than it is.
full of life.
go west.
I have been fortunate to have lived in some great cities in Asia: Seoul, Shanghai, Kuala Lumpur, Singapore, Tokyo and Hong Kong. Only in Seoul and Hong Kong is it possible to take the subway and then within a minutes escape the concrete jungle and hike into real jungle/forest. Love it.
I'd pick a smaller city closer to nature and the country. There's a lot of great options that are only a couple hour train ride away from Tokyo, if/when I wanted to explore. New Zealand is also a no-brainer. And Norther Thailand is always on the mind.
