Sun Peng, our guide, deserves full marks! He was incredibly knowledgeable about Kumamoto throughout the trip, explaining the unique features of each attraction. To be honest, the Aso Boy train wasn't really worth it, haha. 2300 yen per person just to see a mountain; it's not as beautiful as the Ghibli train I rode in Hakone, Tokyo. It was a shame we couldn't go boating in Takachiho Gorge today, but the scenery was still good, though slightly less impressive than Hokkaido's Blue Pond. However, my only complaint about the guide is that he sent us to Takachiho Shrine. It's fine to go, but the path is genuinely difficult, so be prepared. But on the way back to the parking lot, the guide told us to follow Google Maps to the third parking lot, which would have been a disaster! You absolutely must return to that slope and head straight for the third parking lot. When you go to the shrine, there's a fork in the road on that slope; pay attention to the sign indicating the direction to the third parking lot. It's only 300m that way. Do NOT follow the map! A large group of us followed the map, but luckily I had seen the sign on the way there, otherwise, we would have been completely lost trying to find our way back! The cheese mini-bread recommended by the guide was decent, and the cream puffs were also good, filled with ice cream. I didn't try the summer iced tea special. The horse sashimi and barbecue were okay, but don't have high expectations; it's not as good as grilled beef. Next, regarding the guide's recommendations at Kusasenri: I didn't buy the keychains, didn't buy the horse oil cream, but I did buy a fridge magnet. The green house was a bit hard to find, so look carefully. The beef burger was sold out. The only thing I think is worth recommending, which the guide didn't, is the ice cream. If you go, remember to try the ice cream at the museum! Oh, and I also want to mention that the time at Kusasenri is actually very short. If you climb to the observation deck and then come down, and also want to eat and shop, it might be quite rushed. Be prepared to just have ice cream! The fridge magnet is very cute and worth buying for 800 yen! Finally, the Tenkaippin ramen was a bit disappointing; the firm noodles were very salty and not as good as Ippudo in Osaka, haha. Ippudo is also salty (apparently ramen is meant to be paired with sake). As for the Osmanthus fried rice: it tasted like something any Chinese restaurant could make; no need to specifically try it in Japan, hahaha! Overall, this group tour was actually pretty good, just a bit rushed. Of course, that's because there were many places to visit, and it wasn't a self-guided trip, haha! I would still consider a group tour again if I have the chance!
