We will be off to Japan and Seoul, South Korea. Only for 12 days. Should be interesting. No, we aren't bringing bikes. We don't perceive Tokyo as bike friendly, since there's lot so sidewalk riding by locals. Kyoto apparently has a bike share but doubt we have time for cycling.
For Seoul where he's been and loved it, we may use bike share to enjoy the river that runs through the heart of the city.
I just hope there won't be strange politics, an earthquake or typhoon. Need prepare possibly lots of rain in June.
