I been there, mainly the Manikami station
Stop there to go Takaragawa onsen
Around the got a ropeway, ski resort n few other onsen
But one thing disturbing is the place around the station looks abit rundown
Before reaching minakami can oso consider to shibukawa station
From there can go ikaho town, mount haruna or kusatsu (there a bus if im not mistaken)
Beside than that there is the famous car museum which has the original ae86 (correct me if im wrong)
N somewhere around mount haruna is where all the initial d story came from (betul kan???)
This all i know, and please gv tips im sure u know more hahah

Ok. But not all. Look like Feb tips of the month I will post the real kick of minakami
