Oyama Jinja (Mine Honsha)
雄山神社（峰本社）
Oyama Jinja (Mine Honsha) is the ichinomiya — the leading shrine — of the former Ecchu Province, in present-day Toyama. It has no car park of its own. Without a car, a local tourism body gives 1 route from a station (on foot); the station names are listed below. Its principal annual festival (reisai) falls on July 25 every year. We found 1 entry for the shrine in Japan’s national database of designated cultural properties. The nearest other ichinomiya is Amatsu Jinja, 56 km to the north-east in a straight line.

Taken from a local tourism body (とやま観光ナビ 記事「上市・立山の神社」（公益社団法人とやま観光推進機構）, checked 2026-10-08). Station and stop names stay in Japanese so you can match them to signs. Fares and timetables are not given — they change.
Parking
It has no car park of its own.
立山山頂（標高3,003m）に鎮座するため車では到達できない。マイカーは立山駅まで。桂台〜室堂間はマイカー通行禁止で、室堂へは立山黒部アルペンルートを利用する。アルペンルートの営業は11月30日までで、冬季は室堂へのアクセス自体が閉ざされる（峰本社の社務所開設期間は確認できていない）
The note above is in Japanese; it usually records dates when the car park is closed, and the fee.
