Also known as: OONAGURA 100
A small race based near the Janohana garden in Motomiya, Fukushima, built on repeated laps of a roughly 16 km loop. There are no official aid stations: runners resupply from their own cars as a base camp, and entry is limited to past participants and people they refer.
5,686 m of climbing over 166 km (34 m per km). In 2026, 43% of starters finished — a tough one.
