When My sister and I went to Atami which was a small town on the east coast of Japan’s Izu Peninsula in Shizuoka Prefecture, we took a seasonal express train Marine express odoriko.
They services are scheduled to be introduced, running between Tokyo and Izukyu-Shimoda using E259 series 6-car EMUs normally used on Narita Express services.
We enjoyed the ride, and bento for lunch.
