Having chanced upon this little shop Gomafukudo in Kamakura specializing in all things sesame, of course we had to. Essentially smooth milk soft serve, topped with fragrant white sesame. There's also black sesame if I'm not wrong If you ever happen to be here, get their sesame cube - low calories, purely sesame packed in a little cube that wasnt sweet, and darn good, with supposedly loads of health benefits.
