I only take Shinkansen for the route between 新宿 and 軽井沢, so I will not buy JR Pass. I understand it cost JPY5xxx, but I have a question. Is it a single ticket for the route between 新宿 and 軽井沢? That I only need to buy it at JR Shinjuku station without having to buy another one at the interchange station e.g. 大宮?
thanks
