W stands for 'double' and "Asobi" for 'playing'

Our name has two meanings, "W" stands for 'double' and "Asobi" means 'playing' or 'having fun.' So, 'double fun.' Hiking and Biking.

The Azumino area is also famous for its wasabi (Japanese horseradish).

Our name, W-Asobi, reflects this delicious produce.

I believe that Japanese mountains are one of those places that you must visit at least once. Since Japan consists of small mountainous islands, you can experience many different landscapes almost at once - cities, small villages, flat lands with beautiful rice fields (rice is the foundation of Japanese culture), lush forests, green mountains and rocky mountains.

Nagano is the most mountainous prefecture in Japan and best place to see nature and go hiking and biking.

Come visit Japan and have special experience in Nagano with us.

I have worked in Canada, joined the MTB race in Africa, and traveled to Central America, Southeast Asia, Europe, and Oceania. Everywhere, I've tried to see as much nature as possible. Nature is so different in every country and I find that immensely moving.

I love nature. I love cycling, hiking and climbing.

That's why I now live in Nagano, helping world travelers enjoy the nature and culture of Japan.

I am a local guide born and raised in Azumino. After living in Tokyo for about 20 years, I made a U-turn and realized once again how wonderful my hometown is. I am working every day to share the beauty of nature, the goodness of people, and the joy of mountains in Azumino with as many people as possible. From beginners, women, and seniors to overseas guests, we aim to be there for those who need the support of a guide, to keep pace with them, and to create fun memories together.​

I was born and raised in Azumino.
I came back to my hometown after traveled and lived in different places. I love my hometown and my appreciation toward the beautiful nature of Azumino is greater now than when I was young. I feel very lucky to be a guide in such a special place, and I will be very happy to take you to an original journey to go deep into the life in Azumino, as if you are locals.​

I am a local guide, born and raised in Azumino.
A-year stay in London made me interested in traditional Japanese culture, especially cuisine, so I worked in Ryotei(traditional Japanese restaurant) in Kyoto.
I came back home after spending several years in Hokkaido and Kanazawa.
Now I enjoy my life in this farming village in Azumino, making miso and soy sauce from scratch.
I would like to share a part of daily life passed down here over the years, with the beautiful nature of Azumino.​

I’m from the U.S. but am a permanent resident of Japan based in rural Nagano. I’ve always enjoyed the outdoors and over the years have ventured to more than 40 countries for trekking. Still, Japan holds a special place in my heart, and my passion now is sharing it with others; especially the Japanese Alps! I’ve spent 20+ years exploring every corner of the Alps, and have summited the 100 Tallest Mountains of Japan an average of 4 times each. I’m one of only a few guides in Japan who are able to lead all varieties of tours, from relaxed hut-to-hut hiking to extended trail runs and intense multi-day fastpacking trips.​

What is Azumino like?

Azumino is located north of the Matsumoto Basin, which stretches across the central part of Nagano Prefecture, and the mountains of the Northern Alps rise to its west. The view of the mountains from the city shows the beauty of each season.

This area is truly a great area for hiking and cycling.

Sustainability in Rural Areas

Each region has its own unique nature and culture.

This allows us to enjoy the "Asobi" = 'fun' that is unique to each region.


However, it is the local people who maintain and preserve their nature and culture.

Therefore, when you go somewhere, do not just do what you want to. Please leave something for locals.


By doing so, you will be able to enjoy "Asobi" in that field for a long time.


Your actions will not only be enjoyable for you, but will also benefit the local community. And it will return to you. The accumulation of small actions leads to a cycle of sustainability.


We live in this land, and we do small activities in this area.


Please help us, our local community, and nature.

If you are visiting Nagano Prefecture, Japan, please contact us at "W-Asobi" and we will be happy to help you.
