HI, May I know which bus should I take to visit Kamikochi from Shinjuku as I will be travelling onward thereafter to Takayama ? Thxs Tessa
The Alpico bus company runs a bus line between Tokyo and Kamikochi directly called the Sawayaka Shinshu. You can find more information about it on this English language page. Also, there is a luggage handling window at the Kamikochi bus terminal where you can store luggage for between 350 to 600 yen per item (depending on size).
I hope that answers your question. Enjoy your trip!
