Sean here- 立野ダム.
I was fortunate enough to catch a sightseeing train (Minami Aso Railway) gliding past the mostly completed Tateno Dam. Cool weather brings the colors of autumn. A great time of year to catch a train. All aboard!
Some info below about both. Most in Japanese – Although Google translate isn’t perfect, if you have it, it suits the purpose in this case.
