Main Guide Introduction: I absolutely love canyoning, and I even engage in it during my personal time. I was captivated by guiding at NAOC and went on to become the head guide of the canyoning division at Canyons. At our branch in Okutama, I served as the deputy manager, handling everything from carpentry to management. I also have guiding experience in New Zealand. In 2018, I established “Nikko Jumbo” and became its director. I am actively working to showcase the yet undiscovered charms of Nikko.

Fantastic adventure! The canyon was beautiful and Jumbo was the perfect guide. He spoke great English and took care of all the preparations to make the whole experience safe and exhilarating. He also took pictures and videos through out the whole trip. Absolutely make this part of your Nikko itinerary. I couldn’t recommend it enough.

My husband and I took a canyoning tour in June 2023 and we loved it!!!Jumbo San made sure we had all the right gears and guided us really well. He also kept helping us to take photos and videos, even wiping the lens to ensure there were no water droplets.The water was really very fresh and the wetsuit provided kept us sufficiently warm.Read online that other tour places will cancel if the minimum number of pax was not met. Glad that Jumbo went ahead although it was just the two of us.We really had a good time and was the highlight of our trip!100% recommend!!

I am a virgin at canyoning but Jumbo San was super gentle with me.He started by telling us that the hardest part of canyoning was wearing the suit. He was rightThen we took a short and fun walk up the canyon. Climbed small rocks and streams. Dipped into the nice cool waters.The spring waters taste super fresh.Then came the sliding. Wow, it was super fun. Much much more fun than. Theme park.Jumbo San was very detailed in our safety briefing and was very caring all the way.It might look bumpy and all but the thick padding from the wet suit kept me safe.My best time spent this trip!

Amazing canyoning tour with Jumbo! He speaks very good English too which is a bonus since we don’t speak good Japanese. Only 5 minute drive from train station.

The nature of Nikko is wonderful! I really enjoyed playing while feeling the momentum and power of the water flow! The children were alive. I was desperate. It was great fun. The two guides were very nice people. Safety considerations and preparations were thorough. I would like to participate again and recommend it to everyone.

The instructor will also guide you politely and happily! The equipment was neat and canyoning was safe!Accidents on the river are irreversible, so we recommend that you have a guide!

10 times more fun than you can imagine! ! It's so fun that you should participate if you're lost. However, my muscles are sore (laughs).It seems that you need to close your eyes and mouth and hold your breath just before you fall into the water on the slider. If I didn't do it at first, my contacts would come off.But it was so much fun that I forgot the time and had fun!The guide's personality is good, and I got a lot of photos, which made it a good memory!

One of the best experiences I had in Japan! We chose the 3 hour beginner half day course and had a blast going down all of the waterfalls! Our instructor used to work in New Zealand and spoke English which was super helpful as we only had a few japanese speakers in our group. Highly recommend going here while in Nikko!

I came across it hard because I was staying next door.Jumbo is very friendly and professional.The equipment is top, which is necessary given the temperature of the water….Jumbo adapts to you, your level, your fears… in complete safety

It was a lot of fun!!My husband and I experienced it at the beginning of August. Unfortunately, the weather was rainy and the temperature was low, but the other people who made the reservation were all together, and we started with 6 people who were experiencing canyoning for the first time and our guide, Mr. Jumbo. When I entered the river, I felt that the water current was stronger than I imagined, but the course started with a simple dive, and I progressed while getting used to my body and mind. Or slide through unbelievably strong currents.Each time, I was able to do it to the end by explaining my posture and points to note in an easy-to-understand manner. We had a wonderful experience!thank you!

Sorry for being late today😭Thank you for your prompt response nonetheless.Canyoning that I was more worried about than before!It was the best! ️When you go mountain stream fishing, and if you fall here and get swept away, do you feel like you're at the end of the cycle? do i have to slide down? That thrill...It's the best!! ️And Jumbo's indescribable sense of security!I will make an opportunity to participate again.If everyone participates, let's protect the time 🙇‍♂️

River trekking tour Nikko Jumbo guided by Jumbo.The guide was kind and polite, and although I participated for the first time, I enjoyed it many times more than I imagined!We went as a couple, but it is highly recommended for those who like playing in the water and exercising! !I am very satisfied because I can feel the powerful water flow and majestic nature with my body than I thought! !

Our guide, Mr. Jumbo, was a really nice person, and we were able to enjoy the great outdoors safely and happily! !One of the members didn't have confidence in swimming, but he was very supportive, and when the canyoning started, he seemed to be enjoying himself from beginning to end! !I was able to feel the best of summer! Next time, I would like to experience a one-day course! !

One of the leading canyoning spots in Nikko. Our guide, Mr. Jumbo, is friendly and kind to us. It's a small number of people, so it's a homey atmosphere. During the tour, you can enjoy canyoning with peace of mind as you will receive detailed care such as lectures on how to walk, hand signs, and hearings about your health condition. Apparently there is also a one-day course, but this time I went on a half-day three-hour tour, diving near the basin of a waterfall and enjoying a natural waterslide. Full of local fun such as drinking natural spring water on the way!
