Well, I already have 3 days planed to doing nothing so I doubt it. Still have my savings tho, I already have more than enough for the Japan trip so I can take bits from it if it gets too hairy.
Tokyo (obviously) Hakone and Hokaido. Altho I am still planning it out, opted out of a tour and am Instead looking at tourism plans people publish online. It's gonna be an adventure. I am gonna practice a bit of the little Japanese I know.
