Chokai-Sanroku Line is a 23km long local railway along Ugo-honjo~Yashima. Its specialty is Mount. Chokai which makes a perfect scenic view picturing the four seasons. We also operate fun trains whose events change according to the seasons, including "Magokoro (Sincerity) Train"-- where its train attendant will wear the Kasuri kimono as Akita Obako in the morning for 1 round trip. Also, "Omocha (Toy) Train" which started operating in 2018.7 has been a hit among children and adults for its wooden designs.
