If you're visiting Kumamoto Castle and hot springs, you'll want to stay at these hotels! Ranking of popular hotels in Japan based on reviews

 If you're looking for a place accessible by car from Kumamoto Castle, I highly recommend Yutorelo Yamaga in Yamaga Onsen. While Kurokawa Onsen is also fantastic, Yamaga Onsen is famous for its "Bijin-no-Yu," known as "beauty-enhancing water." The water has a unique, silky-smooth, almost viscous texture that feels amazing on the skin. The ryokan itself is a beautifully renovated older building, blending traditional charm with a very chic, modern design. It’s the perfect place to treat yourself and feel "a touch of luxury." Depending on when you go, they sometimes offer day-trip plans that include lunch. You can easily enjoy this experience well within your 20,000 yen budget. Plus, it's very accessible—less than an hour's drive from Kumamoto Castle.

熊本城を見た後、車で温泉に行くなら「ホテルグリーンピア南阿蘇」はいかがでしょうか。黒川温泉も素晴らしいですが、熊本城からは車で1時間半以上かかります。ここ南阿蘇なら約1時間で行けますし、黒川とは違う雄大な景色が楽しめます。露天風呂からの景色が絶景で、目の前に阿蘇山のパノラマが広がり、まさにちょっと高級な気分を味わえますよ。2026年の6月まで改装中ですが、以前は昼食と温泉入浴がセットになった日帰りプランがあったので、予算内で十分楽しめるかと思います。

熊本城の観光後なら、玉名温泉にある「尚玄山荘（しょうげんさんそう）」がおすすめです。黒川温泉も有名ですが、熊本城からは少し遠いです。玉名温泉なら車で約50分とアクセスが良く、運転の負担が少ないですよ。ここには昼食付きの日帰りプランがあります。予算の一人20,000円の中で、懐石料理のような、ちょっと高級なランチが食べられます。温泉は「美人の湯」として知られるトロリとしたお湯で、彼女さんも喜ぶと思います。

Although Ryokan (Japanese inn) is quietly located in the countryside, you can feel the atmosphere of a Japanese Ryokan (Japanese inn) from the entrance. It has a Japanese modern atmosphere, so it is the perfect inn for those who want to relax and spend a relaxing time, and the hot spring is also quite famous. The water is said to be mellow and thick, and many people return for this hot spring. It makes your skin smooth and your hair silky smooth. I think women will be happy. The food is a kaiseki kaiseki（a traditional Japanese multiple course meal ）made with locally produced ingredients from Kumamoto Prefecture, and it is well-balanced and very satisfying, with high-quality horse sashimi and steak that you would never normally be able to eat, seafood, and desserts. They also explain the food thoroughly, so you can enjoy each dish while savoring its flavor. This inn combines the open feeling of nature, the exquisite kaiseki（a traditional Japanese multiple course meal ）unique to Kumamoto, the thick hot spring, and first-class hospitality, so please come and visit us. The accommodation fee is reasonable.
