Chilling in Tokyo

Just received this blip from my youngest son who's out last week in Tokyo with fellow students. They've visited Tokyo university and had spare time for sightseeing too.
My boy isn't much of a writer so I didn't receive other than this blip with a little note to pick them up tonight from the airport; I suppose all went well for them. Their 5th of May will last long time as they're due to arrive in Holland close to midnight ~ he doesn't mention it but I imagine this blip was made little before they had to leave for Tokyo airport to catch their returnflight.

And in a few more days my other son will return to Holland too after being away in Nepal for half a year of time.
