Taken from the shrine's own website (交通アクセス | 甲斐国一宮 浅間神社, 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 a car park (148 spaces in five car parks, two of them taking coaches); the sources we checked do not give a fee.
This routes you to the car park, not to the hall. From this car park to the hall is about 50 m in a straight line (the walk is longer). The location is taken from OpenStreetMap and has not been checked on the ground.
境内駐車場26台／東駐車場52台（大型バス可）／第1駐車場20台／第2駐車場20台（日曜祝日のみ）／大鳥居前駐車場30台（大型バス可）。料金の記載はない（公式「駐車場のご案内」の図）。やまなし観光推進機構は普通車100台・バス約10台としている
The note above is in Japanese; it usually records dates when the car park is closed, and the fee.
