White and lake blue are the colours on the flag of Ryusen State. Ryusen's small environmental train around the city is white and blue. The 40-minute journey of the small train around the city passes through all the important scenic spots in the city. The small train travels through the streets and lanes of Ryusen. It has a lovely appearance and a little cartoon, like a small train for children in an amusement park. We didn't take it. According to the internet, the small train around the city starts its first train at 11 a.m. at the five-star Schweizerhof Hotel on the lakeside, which provides English and German interpretation services. Tickets are available at the Tourist Consultation Center in the Ryusen Railway Station.
