(Translated by Google) If you want to move your body and play well during the summer vacation, come on! There is a difficult athletic course and it is challenging. It seems that you can have a barbecue if you are hungry, and there is also a cool lodge where you can take a break. You can enjoy a wide range of things from small children to large children. (Original) 夏休み身体を動かしてしっかり遊びたい方は是非！難易度の高いアスレチックコースがあり、やり応えがあります。お腹が空いたらバーベキューなんかも出来るみたいですし、休憩出来る涼しいロッジもあります。小さい子から大きな子まで幅広く楽しめます。

We were here on a weekday afternoon and there were only a few people there, so paying admission and getting in was a breeze. My 1 year old had so much fun and didn't want to leave, and we were very impressed and intrigued by the whole area and equipment they had set up. It's obviously not a brand new park and the equipment reflects its age, but it's not a problem for us because it all still felt well maintained and safe. We hope to come back again sometime in the future!

What a fun Forest Kingdom!! Not just for kids but also for the adults! It was ¥900 each day pass for adults and ¥700 for kids age 4-12. There are plenty of things to do. We brought our pop up tent 🏕 to relax while we watch our daughter play. Our daughter didn’t want to go and said “I wanna stay here forever!!”

(Translated by Google) I used it for skiing. Since it was the first time for my child (in the lower grades of elementary school) to ski, I asked for a ski class, and the parents split up at the ski resort. In the children's ski class, we used equipment rental and photo shooting options, but I was very impressed with how easy it was to understand and how politely they answered my inquiries over the phone. Even when I asked the children, the ski lessons seemed to be a lot of fun and they seemed satisfied. In addition, he taught me the basics of technology, so from now on, the whole family will be able to enjoy skiing together. In addition, it was very helpful to respond flexibly to problems with children. Thank you very much. Also, as a parent, I was able to fully enjoy Mt. Oyama, which was very refreshing. There are plenty of photos and videos taken, and I am very satisfied that the whole family can see it. (Original) スキーで利用しました。 子ども（小学校低学年）は初めてのスキーだったのでスキー教室をお願いし、親はスキー場で分かれて別行動にしました。 こどもスキー教室では道具のレンタルや写真撮影オプションなどを利用しましたが、電話での内容問合せにも丁寧に受け答えしていただき、大変分かりやすく好印象でした。 こどもに聞いてもスキー教室は大変楽しかったようで、満足そうでした。また技術的にも基本をシッカリと教えていただいており、次からは家族みんなでスキーを楽しめそうです。また子どものトラブルにも柔軟に対応していただき大変助かりました。ありがとうございます。 また親としても大山を全身で堪能できて、大変リフレッシュできました。 撮影していただいた写真や動画もたっぷり有り、家族みんなで見れて、大満足です。

Very nice place for children and family to play and do camping. The entrance ticket is 1500yen while free pass is 2000yen - of course free pass ticket seems to be more reasonable, but people in same family need to be same ticket, so adults need to buy free pass ticket too even do not play anything :(

We went on a weekend holiday so the park was packed. We waited long to get checked. During the wait, the kids got so thirsty and we had a little trouble finding potable water. They should put up signs on the faucets if it safe for drinking or not. Rest of amenities are good. The kids enjoyed the playgrounds.

I can't even begin to explain how whimsical and wonderful this place is. We spent the entire morning, had lunch, spent the afternoon, had ice cream, and came home!! The kids had the best time and got to build confidence and problem solve through the obstacle course. Highly recommend it to anyone with kids!

A good place for camping and to have bbq! There is an obstacle course and treasure hunt activity, good for both adults and children. You may pay a fee to spend a whole day at the adventure course. There is plenty of free parking available, and the you may bring your dogs to the park.

The facility is over 40 years old and it shows the age. Kids had great time, but feel like the things are over priced.

Big site and full of games to challenge! Prepare half day to complete the course!

(Translated by Google) There are 2 field athletic courses, but the advanced course has quite a large scale of playground equipment, and some of them are difficult even for adults. In addition, there are playground equipment such as tree houses, green sliders, shuriken throwing, air hockey, making Baumkuchen, ice cream, pizza, crafts, activities such as shower climbing, cycling, trekking and skiing, camping sites and dog runs. , you can enjoy as much as you want. I don't think a family with elementary and junior high school students can play all day long. The hands-on experience basically requires a reservation by the day before, but depending on the situation, it may be possible even on the day. There are various discounts on the admission fee, including the Montbell Club. (Original) フィールドアスレチックが2コースあるが、上級コースは遊具の規模がかなり大きく、大人でも難しいものもある。 他にもツリーハウス、グリーンスライダー、手裏剣投げ、エアホッケーなどの遊具、バウムクーヘン、アイスクリーム、ピザなどの作成、クラフト系、シャワークライミングやサイクリング、トレッキングやスキーなどのアクティビティ系、キャンプ場やドッグランまであり、いくらでも楽しめる。 小中学生連れのファミリーなら丸一日利用しても遊びきれないと思う。 体験系は基本的に前日までに予約が必要だが、状況によっては当日でも可能な場合もあり。 入場料はモンベルクラブを始め様々な割引あり。
