Keikoku Bettei MOCHI-NO-KI / chiba Katsuura・Kamogawa 59


It says ‘Mochi-no-ki’ is planted in a shrine as a tree for a Japanese God and gives you a good fortune.
With the thought to wish the peace and happiness of the guests, many ‘Mochi-no-ki’are planted around this hotel . 

It takes only 2 hours from Tokyo and a spacious and beautiful nature is waiting for you.
You can have a good mental condition with a quiet valley called ‘Yoro Keikoku’ and a murmuring of the mountain stream. 

Concept Room with a hot spring Jacuzzi opened in February 2015 and uses natural materials.
You can spend time around the natural colored wooden floor or furniture.

Boso Peninsula is a warm and rich cultivated field surrounding the ocean and the river. We cook seasonal dishes using the local ingredients with our heart.
There is a resting space in the garden along Yoro river so you can find yourself.
You can enjoy looking at the changing sight every season.

It is not too gorgeous here but we want you to heal your daily fatigue slowly instead.
‘Be Happy with your heart’: This is the way that MOCHI-N0-KI suggest you spend your time in the valley.

Read more 紅葉も素敵でゆったりとした時間を過ごすことができました。改装されて間もないこともあり、とてもキレイで素敵なお宿でした。温泉ジャグジー付きのお部屋だったのですが、大風呂もお部屋から近いことや、大きなお宿ではないので他のお客様とイモ洗い状態になることもなく、気兼ねなく何度も大風呂に行きました。お風呂から眺めるお庭もとっても素敵で心身ともにリフレッシュできました。若い人はモダンなお部屋(ジャグジー)も良いかと思うのですが、年配の方は露天風呂(半露天でも)の方が温泉に入った気分になるのでは?と感じました。やっぱり大自然を感じながら温泉を味わうのは醍醐味ですものね!お食事も大満足です!これといって大げさに高級食材を使っているわけではありませんが、一つ一つに季節感を出し、丁寧に作ってくださっているのを感じました。このお値段でお部屋、お食事のこのクオリティーは素晴らしいと思います。程よい隠れ家感とモダン感とこじんまり感がとても心地よいお宿でした。お世話になりました。

The autumn leaves were nice and I had a relaxing time. It was a very nice and nice inn as it was recently renovated. Although it was a room with a hot spring jacuzzi, the large bath was also close to the room and it was not a large inn so it was not washed with other customers, so I went to the large bath many times without hesitation . The garden seen from the bath was very nice and refreshed both physically and mentally. Young people think that a modern room (jacuzzi) is good, but if you are an elderly person, the open-air bath (even semi-open-air) feels like having entered a hot spring? I felt that. After all, enjoying the hot springs while feeling the great nature is the best part! The meal is also very satisfying! This is not to say that high-quality ingredients are used exaggeratedly, but I felt that each of them produced a sense of the seasons and made it carefully. I think the quality of the room and food at this price is wonderful. It was a very comfortable inn with a moderate retreat, a modern feel and a small feeling. thank you for helping me.

You will be impressed every time with a beautiful treat that feels the season. In the morning walk, I met white sharks, and I could observe frogs, frogs and small fishes up close. On 9/7, the amount of water in the river was small, but I was still able to breathe cold air like the morning. Felice's balcony is always comfortable. Thank you very much.

Read more 6月7日にお世話になりました。 あいにくの小雨で楽しみにしていた螢は見ることができませんでしたが渓流添いの部屋からバルコニーに出ると 一晩中かじかの鳴く声が聞こえ 始めて聴く美しい鳴き声にびっくりしました。さすが渓流の歌姫! 夕食 朝食ともに量 質ともに大満足です。会話の中で結婚記念日で来たことを話すと係のOさんがお祝いして下さりワインもいただきました。本当にありがとうございました。お話も楽しかったです。 静かでゆっくり過ごせる宿を房総で見つけ 毎年の結婚記念日旅行はもちの木にしようか?と夫と話しています。次は螢が見られますように… のんびりしたくなったら 来年まで待てずまたお世話になるかもしれませんがよろしくです。

I am indebted on June 7th. Unfortunately, I could not see the niece I was looking forward to because of the small rain, but when I went out to the balcony from the room of the mountain stream I heard a roaring voice all night and I was amazed by the beautiful cry that I heard for the first time. Truly a mountain stream diva! Dinner Both the breakfast and the quantity and quality are very satisfying. Mr. O, who was in charge of speaking in the conversation to talk about coming on wedding anniversary, celebrated and received wine. I'm really thankful to you. The story was also fun. Find a hotel in Boso where you can spend time quietly and slowly. Talking with her husband. Next time you will see a whale ... If you want to relax, wait until next year and you may be taken care of again.
