Lake Onuma
Enroute to Hakodate (less than an hours' car drive North of Hakodate), you can swing by to the Onuma park. It's somewhat like swamp land where bridges connect the bodies of water / lakes and there's also a good view of the volcano in the region.
There's plenty of space and serenity in the park. Good for walking and enjoying nature.
