That`s me! Feel free to contact me if you would like to rent a Carryme during your trip. If you would just like to try one (You can also try my Curve SL if you`d like) just let me know and I will try to meet you (I`m in Yokohama) If you have some more time I`d be happy to show you some of the really great bike shops here, including Loro, Y`s Road, Green Cycle Station, and a Cycly used bike shop. Also, good idea to keep your eye on Tokyo Craigslist.
Check out Yokohama Rides and Rentals on facebook for my contact info.
