The Oze National Park, which sprawls across four prefectures - Gunma, Fukushima, Niigata and Tochigi - is known for its well-preserved and vast yet delicate nature. Designated as a Special National Monument of Japan, Oze is also included in the List of Wetlands of International Importance under the Ramsar Convention. In the Taisho Era in the early 20th century, the electric power supplier to the area at that time acquired some land in Oze for generating electricity and that land was passed on to TEPCO when the company was founded.
For around 60 years since then, together with the local communities and our group company Tokyo Power Technology Ltd., we have been working to protect this natural environment as well as to provide visitors with opportunities to enjoy its nature. Our specific activities include restoration of the wetland vegetation, installing and maintaining wooden paths, building and managing public toilets and mountain lodges, and offering guided nature tours.

What is Oze?

Oze is a great storehouse of nature, both magnificent and subtle, located in the middle of Japan.

Oze Notebook

Oze National Park features natural scenery throughout the changing seasons that provides endless fascination for the many visitors during the year.
The wooden paths of the park are essential for protecting its precious beauty and the safety of hikers. These wooden paths, which appear to run everywhere throughout the vast wetlands, have received extensive praise from persons who have visited them as representative scenery of Oze.

When these wooden paths can no longer serve as walkways, they are recycled to create "Oze Wooden Path Paper".

With the cooperation of numerous persons associated with Oze, we created this "Oze Notebook" using Oze Paper for all pages this year.
This book allows you to enjoy the scenery and attractions of Oze in your home or office.

They can also be used for business due to being A5 size and packed with information.
It includes excellent illustrations and photos that will have you wanting to visit Oze before you know it.
We have also created a version in English so that foreigners can also learn about Oze, and its surrounding attractions and beauty.
