Hokuriku Shinkansen北陸新幹線
Tokyo → Joetsu-Myōkō in ~2 hours, every 30–60 minutes. From Joetsu-Myōkō, a 12-minute local train (or free seasonal shuttle to Akakura) reaches the village.
Most Kagayaki services skip Joetsu-Myōkō; check the timetable. Tsurugi shuttles serve western Hokuriku only, not this stop.
