When I heard that I was going to walk from Konandai to Kamakura/Ofuna in Kanagawa Prefecture I thought "What?". I didn't want to walk on the street. However, the walk was on very nice trails and was about 20km, with lots of up/down trails. It was very interesting to see places that I had only seen from a car or train when I was hiking. Mt. Fuji looked very nice, too. Looking at the damage from Typhoon 19 was incredible. There were hundreds and hundreds of trees snapped in half. The awesome power of nature. I recommend this hike to anyone who wants a good workout in order to train for something bigger. It would also be good for rehabilitation. There are many signs that say "Do not enter/ Do not hike here" Don't worry about them. It is not bad. Go for it!
