adex base was created to share the unique natural environment and culture of the Noboribetsu region with our adventurer visitors. We offer a range of activities that explore our region through the dramatic changes of the seasons, sharing the beauty and challenges that nature has to offer, from snowshoeing in a frozen forest to paddling on a crystal clear caldera lake, to walking in a geothermal wonderland, and experiencing Ainu culture first-hand. And much more.
Our activities are curated to provide a choice to suit your interests and fitness, easy introductory experiences to hard-core adventures, and are available with English and/or Japanese speaking guides. Be sure to read the descriptions, conditions and clothing requirements before signing up for an activity. If you have any questions, please email us.
We also curate private activities for families and small groups. If you would like to create a custom activity to suit your family/group’s interests and abilities, from an introductory experience through to a major adventure, please contact us. As our capacity is limited by the availability of guides, booking early is recommended.
We look forward to sharing our special home in the world with you soon.
