Translation guide
In Japanese, the way you say 'mountain climbing' depends on the type of climbing—whether it's a casual hike, a serious climb, or technical mountaineering. The most common and versatile term is 登山 (とざん), but other words like ハイキング (haikingu) and 山登り (やまのぼり) are used for lighter activities.
