I visited in mid-May, and the weather was pleasantly cool and comfortable. The breeze blowing through nature was truly refreshing. The observation deck overlooking Lake Biwa offered a magnificent view, and there were plenty of photogenic spots, including rainbow-colored umbrellas for rent and colorful photo opportunities. The parfait shop with lamps also had a lovely atmosphere. It was a relaxing spot where I could enjoy nature and scenery to the fullest!
It was so much fun! The kids loved it! And it was cheap too!! The scenery was great, the gondola ride was fun, and we could do so many activities for this price?! I was so surprised. We'll definitely go again!!
