Kasuien Minami

Tamatsukuri's big, polished all-rounder: 108 rooms with plenty of free-flowing in-room onsen baths, a rooftop view bath, sea-bream rice and very high guest scores — but it's large enough for check-in queues, tour groups and a crowded breakfast

Kasuien Minami began as the annex of Minamikan, a Matsue inn founded in 1888, and is now one of Tamatsukuri Onsen's largest ryokan: 108 rooms across three wings, renovated in stages (most recently the Kisshō floor in July 2026). The water is Tamatsukuri's sodium-calcium sulphate-chloride spring — the classic 'beauty water', mildly alkaline and slightly salty — and many rooms have their own bath on the spring, which the inn describes as free-flowing; it doesn't say whether the public baths are recirculated. Japanese guests rate it highly everywhere: 4.7 across 2,113 reviews on one major site, 4.72 across 282 on another and 4.66 across 1,501 on a third. They praise spacious, spotless renovated rooms, kaiseki in private or semi-private dining rooms with Shimane wagyu, a seaweed hotpot and the Minami family's sea-bream rice (an add-on), a breakfast buffet of 50-plus dishes with Lake Shinji clam soup, and free lounges and a kids' room. The downsides of its size show in 2025–2026 reviews: a 50-minute wait to reach a room during a holiday week, staff coordination slips (a missed station pickup, a lost car key, wrong times), tour groups and a crowded breakfast, guests now carrying their own luggage, and room baths that run too hot or too cool. Two-person stays with two meals in 2024–2025 cost about ¥82,000–86,000.
