We went to Nishihira Field Park in Matsudamachi, Kanagawa Prefecture on Golden Week in Japan (1 week holiday in May). Our family enjoyed the view of Mt. Fuji and stroll around the herb garden, and the ride on mini-SL train. There was also mini Odakyu Romance Car train but we chose to ride on SL train only. It was fun when the train made a switchback to a slope.
The Romancecar is Odakyu Electric Railway’s name for its limited express luxury tourist services south-west of Tokyo.
