I have visited japan so much and I swear most of the famous spots are crowded year-round. But if you want an actually peaceful mountain area with insane scenery, Okuhida (near Takayama) is where locals go. The entire area is surrounded by deep forests and mountains, and it’s known for its outdoor hot springs. The best part? Almost zero foreign tourists. Even Japanese tourists come in small numbers compared to Hakone or Nikko. My go-to tip is to visit the Shinhotaka Ropeway around 4 PM. The daytime crowds are gone, and the top platform gives you a view of the Japanese Alps with barely anyone around. You can stay in ryokans, small inns, or Airbnbs in the surrounding villages tons of options without big tourist traffic. If you want that quiet, traditional Japan feel with mountain air and hot springs, Okuhida is honestly unbeatable.
