Mikazuki Sea-Park Hotel Katsuura
7,4/10 Very good - Based on 157 reviews
Mikazuki Sea‑Park Hotel Katsuura occupies a seafront position on the Katsuura coast of Chiba Prefecture, presented as a large-scale coastal ryokan-style resort that blends traditional Japanese elements with modern hotel services. Guest accommodation spans Japanese and Japanese‑Western rooms, many with tatami areas and ocean views, and rooms are fitted with standard conveniences such as air conditioning, flat screens and private bathrooms. The property is arranged to serve both families and groups, with banquet and conference capacity alongside leisure facilities aimed at multi‑generational stays.
This property is promoted as a ryokan with onsen in Chiba and centres its bathing offer on a high‑level observatory hot‑spring bath located about 40 metres above sea level for expansive Pacific views, plus the Aqua Palace dome that houses year‑round water attractions (an indoor action spa and an outdoor sky spa where swimwear is required). The complex includes a large public bathing area, sauna and jacuzzi, and an indoor pool; it does not provide reservable private onsen, so guests should expect communal hot‑spring facilities rather than private baths. As a ryokan with onsen, it emphasises sea views and shared spa experiences.
Onsite dining focuses on buffet service with seafood and varied Japanese and international options, supported by bars and casual outlets, while additional amenities include spa treatments, beauty services, game and entertainment rooms, and family recreation. Practical services include a 24‑hour reception, shuttle options and guest parking, and the hotel is within a short walk of local rail connections and coastal attractions, making it a convenient base for exploring the eastern Boso coastline. The overall offer is geared toward guests seeking ocean views paired with comprehensive communal spa and leisure facilities.

Positive Reviews
Excellent beachfront location and ocean views
Many guests praised the hotel's location right on the sea — rooms offer clear ocean views and the property is close to the station and shore, making it convenient and scenic.
Spacious, comfortable rooms
Multiple reviews mention large rooms that are comfortable for families and couples, providing good space to relax.
Relaxing onsen and bathing facilities
Guests frequently enjoyed the onsen and public baths — they described the bathing areas as pleasant, with good views and relaxing amenities (including free massage chairs near the onsen).
Family-friendly amenities and pool/waterpark access
The hotel is recommended for families: free pool access, nearby Aqua Palace with rooftop hot tubs/saunas and water attractions, and activities that children enjoyed were repeatedly noted.
Good food and overall value
Many reviewers complimented the meals (buffet/dinner) as tasty and generous, and several felt the hotel offered good value for the price, especially for family stays.
Negative Reviews
Outdated rooms and furnishings
Several guests commented that rooms and equipment feel old and in need of renovation, with some saying the décor and furniture appear dated.
Limited breakfast choices and food replenishment issues
Some reviewers found the breakfast buffet limited (few vegetarian options, little or no fresh fruit, canned fruit served) and reported items like sashimi were not properly replenished at busy times.
Weak shower pressure and limited bath variation/temperature
There were multiple complaints about weak shower pressure in the large bath and that the onsen had limited variety and sometimes lukewarm water temperatures, reducing the bathing experience for some guests.
Maintenance, cleanliness and housekeeping incidents
Isolated but serious issues were reported: unpleasant odours outside a specific room (reported like urine smell), and an instance of housekeeping entering a room unexpectedly before checkout. These suggest occasional lapses in cleaning/inspection and room privacy procedures.
Operational and access issues (keys, pool hours, communication)
Guests noted practical problems such as difficult or missing keys/card issues and staff communication lapses about facilities, limited pool/waterpark hours or access (affecting late arrivals), narrow parking spaces, early checkout time (10:00) and lack of amenities like a coin laundry.
