Unfortunately, we weren't able to see the aurora this time, but the guide checked the aurora conditions as we moved. During the move, he explained the route to each location. Even though we didn't see the aurora, we were able to experience a starry sky that is hard to find in Japan. P.S. It's amazing how bright the moonlight is, so it's a good idea to check the lunar cycle.
