Ryan very kindly offered to pick us up at the station with his car, which was appreciated, because we had a little trouble with orientation in Tokyo ( few street names etc).
Then he took 15 mn of his time to have a tea, and explain what we could do. I wish i had stayed longer in his apartement, that was well organized and very well equipped.
It's not far from Shibuya, and conveniences stores are nearby.
and Ryan is really kind and helpful!
