It was great! There were guides available who spoke Korean, Japanese, Chinese, and English, and they were all very kind and repeatedly provided information and explanations. They answered all our questions immediately and were very thorough! I was worried because lunch wasn't included, thinking, 'Does that mean I can't take the free shuttle, and I'll have to eat onigiri on the bus?' But it turned out we could use a taxi shuttle (300 yen per person) and eat at restaurants near the Volcano Museum, which was a pleasant surprise! However, the price of the restaurant meal wasn't much different from the bulgogi that comes with the included lunch, so next time I'll probably opt for the lunch. Haha. On the other hand, the restaurant next to the museum had a diverse menu, and the food was delicious! Horse meat is famous, and so is Akagyu (red cattle)... Rice is also famous for being delicious, so we tried the Wagyu donburi, horse meat yukhoe bibimbap, and ramen. The Wagyu donburi was expensive but incredibly delicious. I don't recommend the horse meat yukhoe bibimbap. It tasted good, but when the rice, sauce, yukhoe, and raw egg were mixed, it became a bit mushy. The ramen was also delicious, and the rice itself was tasty! The unlimited miso soup and rice were an added bonus! Also, the milk soft-serve ice cream and volcanic ash coffee were delicious. Kusasenri was mostly obscured by fog, which was a bit disappointing, but it was nice to smell the sulfur, and the boat experience was a lot of fun! I highly recommend the boat ride! Anyway, I had a lot of worries, but the guides were skilled at leading the tour, everything went smoothly, and the schedule was kept perfectly, which was great! I'll probably use this service again! GoGoTrip? GoGoGo? Anyway... they also explained the history and myths, which was entertaining!
