Thank you, tour guide Zhao, for your explanation. You were very helpful, and the overall experience was great. The weather was perfect that day, and we could see Mount Fuji clearly from both Lake Yamanaka and Lake Kawaguchi. Plus, it was cherry blossom season, so the combination of mountains, water, and flowers was truly beautiful!
