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.
The drive up to the cape is through a narrow uphill road that cuts through a local cemetary. There isn't much to do at the cape although the scenary of the thrashing waves and wide expanse of dark blue sea is impressive. Get ready to be thrashed by the wind too.
It was rain. But it is not flood.If the weather was fine. you can see a beautifulMt.Komagadake.Onuma park is the new most beautiful scene in Japan.
