This project is a highly valuable and worthwhile itinerary. I originally read online that Kumamoto Castle might be under maintenance and closed for visitors, but fortunately, we successfully visited! The ginkgo and cherry trees are truly beautiful – the timing was just right. If you want to eat and shop, you need to pick up the pace and take fewer photos, then you'll have a chance to try the food. The tempura is super delicious and a must-try; it's sold alongside the bear-shaped cakes, and both are really tasty and cute. Aso Volcano was a pity... we couldn't visit due to the red alert, which was the only disappointment. The tour guide said it's very rare to encounter Aso Volcano on a green alert, and even the guide couldn't predict the timing. The scenery is truly beautiful, and by the way, you absolutely must bring a windbreaker! We thought it wouldn't be cold, but it was freezing. You should try the coffee, and if you want to experience buying a lucky bag in Japan, you can get one. The lucky bags contain a selection of the store's key items, so if you don't want to pick out souvenirs, you can just buy a lucky bag; there are quite a few things inside that you can give as gifts! It's excellent value for money, though it did rain a few times and disrupted things! Oh, and there's a supermarket where you should definitely buy whatever you can. Aso Musume strawberries are very popular, but they are incredibly sweet and delicious, not sour at all, with a fragrant strawberry aroma. There are also other varieties of strawberries, and the prices are all excellent!
