B.B.BASE monitor tour of JR is carried out only in the Internet sale on Saturday, February 11, 2023.
"B.B.BASE" does not dismantle a bicycle and is the special train which can be just put on a cycle rack in the car. It was released, and the monitor tour that could make a round trip of Minami Boso of the early spring on such "B.B.BASE" was started.
A favorite car and "the cyclist course" where I can go to, there are two plans of "the bus trip course" that can be enjoyed relaxedly by bus.
