Some places I would like to go to are Rissaku ji Temple, Zao ropeway, Moga I River Boat ride and Yamagata Museum of Art/Yamagata Castle. Do you have suggestions for any of these specific places?
I presume you mean Tendo in Yamagata.
It's next to Yamagata Airport and has the Yamagata bullet train running through. But that's it. Within the city, your only options are buses, walking, and taxis. As far as going to some other city or town, unless you give more specific info, it's impossible to elaborate.
