Enjoy some of the clearest waters on the Boso Peninsula at the rocky shores and beaches! Go between the beach and pool in your swimwear! [Ocean views from every room]

The majestic Pacific Ocean is just a 0-minute walk away! Only a 10-minute drive to Kamogawa Sea World! Enjoy both the rocky shores and sandy beaches with exceptional water clarity, as well as the pool, all accessible in swimwear on foot. This all-ocean-view Hotel is perfect for exploring Boso and Kamogawa or simply enjoying the sea. At our buffet, don't miss our highly recommended seafood feast "Original Nokkedon"!

  • We stayed for one night to celebrate a family birthday, and the ocean view right in front of us from the balcony was incredible. It felt so open and relaxing that we found ourselves just gazing at the scenery for a while. The only thing was that we wished there had been chairs out there, and having a screen door would have let us enjoy the sea breeze and sound of the waves without using the air conditioner.The room had been beautifully renovated, and both the bed and futon were very comfortable. The amenities were fully stocked with everything we needed, and even the towels were thick and pleasant to use. The bathroom was also spotless and very user-friendly.What impressed us most was the buffet—everything tasted great, with an excellent variety. For dinner, we especially enjoyed shabu-shabu, sea bream rice, sashimi, and items from the live kitchen like chicken and kakiage tempura fritters. At breakfast, the French toast and pressed yogurt were particularly delicious. I asked in advance whether a birthday dessert plate could be arranged, but it wasn’t available, which was disappointing; however, they kindly gifted us a bottle of wine at dinner, which made us very happy. Thank you so much.The indoor bath was a bit hot for our taste, but the outdoor open-air bath was perfect. Soaking while looking up at the night sky helped all our fatigue melt away.All of the staff were extremely kind—we felt we received hospitality beyond what we paid for. Our whole family loved it as well. We would definitely like to book again when visiting Kamogawa.

  • We are big fans of Hotel Green Plaza Kamogawa and have been staying here for over 20 years. Every visit, the warm hospitality makes us genuinely happy to be back. We are always deeply grateful for the staff’s thoughtful attention to detail and kind, attentive service. With ocean views from the rooms, a delicious buffet, and relaxing hot springs, it has become our family’s go-to hotel. We look forward to staying again.
