Onuma Koen Station Bag storage

Hi, do you know if there are storage area or locker in Onuma Koen station ? I and family intend to stop there a few hours on way to Sapporo, do not want to carry the luggage around. Thanks.

There are coin lockers. If they are full or too small, ask the station staff. They should be able to help by taking care of the luggage themselves or point you somewhere where you can store your luggage.

The following indicates that there are twelve 400 yen medium and four 500 yen large size coin lockers in Onuma JR station.
