The Property by Lake Kameyama, the largest lake in Chiba Prefecture, offers a serene experience surrounded by the tranquility of nature. This Onsen Ryokan features 14 Rooms, where guests can enjoy the abundant chocolate-colored natural hot spring water flowing directly from the source.

The cuisine is prepared using ingredients sourced through a nationwide network of brokers and purchases from the Toyosu Market.

  • The building itself is old, but it’s well cleaned and feels pleasant.There are several private baths available for an additional fee, and relaxing in the hot water is truly soothing.Above all, the meals are outstanding—if you enjoy Japanese cuisine, we highly recommend choosing a Plan with meals included. The staff were all kind and welcoming with warm smiles, making this a wonderful Hotel full of heartfelt hospitality.

  • With part of the Kururi Line being discontinued, I took the train as a keepsake trip and finally visited Kameyama Onsen, which I had long wanted to see. I was thoroughly satisfied with the chocolate-colored mineral spring water and the delicious meals featuring an abundance of local specialties from both the sea and the mountains. Surrounded by Lake Kameyama’s nature, I soaked up plenty of refreshing natural ions and felt reenergized.I would love to visit again.

Introduction of the Accommodation

image e_ss_huro2.jpg

100% natural chocolate-colored Onsen directly from the source.

Abundant water flow gushing over 600 liters per minute from 2000 meters underground. Onsen water flows out from a slightly opened pipe. When smelled, a faint sulfur scent can be detected. In Chiba Prefecture, due to the absence of underground magma, the temperature of the onsen water is a low 26.4°C, but to ensure guests can enjoy a comfortable bath, the water is circulated and heated while mixing with fresh water.
