What guests think

At Grand Mercure Minamiboso Resort & Spa, guests describe a scenic, family-focused resort with spacious grounds, large hot-spring baths, plentiful kids' play areas and a pool, plus an all-inclusive lounge offering drinks and snacks, all at good value for families.

Many rooms are spacious with ocean views, though some remain dated or unrenovated, with occasional noise, weak Wi-Fi, or patchy air-conditioning. Dinner feedback is mixed: large, kid-leaning buffets can feel crowded or repetitive, and late seating windows shorten eating time, while breakfast draws stronger reviews. Staff are frequently kind and helpful, but check-in queues and a few booking or communication errors are noted; housekeeping is generally fine yet sporadic hairs, dust, or insects are reported. Expect a lively, family-friendly seaside stay.

オールインクルーシブとスパにとても癒されました。子ども２人を連れた家族４人で伺いました。早めについてチェックインした後、鍵の受け渡しは3時からということで子ども達は子ども広場で遊ばせていただきました。3時になるとラウンジがオープンして、ビールやワインなど、お菓子含めて十分に堪能出来ました。部屋は昔ながらの和室で、ユニットバスでしたが、とても綺麗な大浴場があるので、問題なかったです。夕食も、メニューが豊富で、蒸した美味しい牡蠣とアルコールも飲み放題で最高でした。子ども達は綿アメ作りにハマっていました。ホテルから海までの散歩道も自然豊かでとても気持ちよかったです。また、どこのスタッフさんも子ども達に優しくしてくれてとても好感が持てました。また行きたいです。
