Sounds very similar to my experience. Forgot about
haribo and jelly beans as I’m not keen on them.
In the morning I took a JR train from Yokohama to Kita-Kamakura and walked around a couple of temples before catching a train back in time to checkout at 2pm. Kita-Kamakura is one stop before Kamakura on the way to Zushi and about 25 minutes from Yokohama if you pick a direct train. Emgaju-ji Temple almost next to Kita-Kamakura station is recommended. From Engaku-ji to Tsurugaoka Hachimangū, a big Shinto shrine, is about one mile. After visitingTsurugaoka Hachimangū, walk to Kamakura Station for a train back to Yokohama.
I expect it will be very busy tomorrow with people going to see autumn colours. This was at the entrance to Engaku-ji Temple 11 days ago.
By the way, points from my stay took 10 days to posts.
