家族4人（大人2人小学生2人）で利用させていただきまました。当初予定していた温泉旅館がとれず急遽こちらを予約しました。まったく違うタイプの宿となりましたが、心温まるおもてなしのペンションで当初の予定よりかえって良かったみたいです。隅々まで掃除が行き届き快適でした。お風呂も温泉旅館とはちがい小さいですが、やわらかなお湯で気持ちよく温まれました。12月31日泊と年越しのお泊りで通常のお食事に加え夜はお蕎麦、朝はお雑煮などを出していただけて嬉しかったです。またお外にあるハンモックで寒空の下にもかかわらず子供たちが楽しく遊んでいました。違う季節だとまた違った楽しみがありそうです。

屋主熱情又親切的招待，早、晚餐都弄得美味，很有心思，房間住得舒服，周邊環境淸新又優美，唯獨交通有些限制，只要一架5號巴士到，如果自駕遊就十分理想。真多謝屋主那麼窩心，幫忙用車送往車站。日後有機會再遊湖，都會選擇住宿，交通應該不成問題

Fantastic warm welcome from this family run pension, they go out of their way for their guests. Rooms are basic but had what we needed. Food was tasty and beautifully presented and it was lovely to use the hot bath after a long day’s walking. In the days of corporate hotels with no individuality this is a breath of fresh air.

What I liked about was the owner was friendly and extremely helpful, he drove us back to the Kawaguchi ko station in the rain when he only had to take us to the nearest bus stop. We had lovely dinner/breakfast and 24 hour onsen bath and had private feel in the forest. I would recommend here and would stay again.

Great place and friendly owners

It's definitely my top 3 travel accommodation experience in Japan. (I've visited Japan more than 10 times,and more than 100 nights totally.) Ayumu San,the hostel owner, is a great man,and you can communicate with him easily. The foods are GREAT and you can feel they cook with their professional skills and warm heart. It comforted me after whole day full schedule and made me feel like home. Everything is almost perfect,and I do really thank for Ayumu san and his parents gaving me an unforgettable memory during Mt. Fuji trip. I strongly recommend this hostel if you want to visit Mt. Fuji and enjoy Japanese Omotenashi" And I will choose here again definitely when I visit Mt. Fuji next time. 強烈推薦這間性價比超高的民宿(我住了兩晚) 老闆親切且用英文溝通無礙早晚餐都精緻好吃，看得出主人的用心！建議如果開車來玩的朋友(民宿也有提供接送)真的可以考慮這間很棒的民宿請記得當個好旅客，別丟華人(尤其是我們台灣)的臉喔(笑)
