Oze National Park has a long history. It was rst designated as part of the Nikko National Park in 1934; however, the Oze area was divided from the Nikko National Park in 2007. It was then incorporated with surrounding areas such as Mt. Aizukoma, Mt. Tashiro, and Mt. Taishaku and designated as the 29th national park. The name, Oze is well-known for being sung in the Japanese traditional song, “Natsu-no-Omoide (Memories of Summer).” It features characteristic landscape consisting of Ozegahara Marsh, the largest high marsh on the main island (Honshu), Ozenuma Swamp, the volcanic lake created from Tadami River, and surrounding mountains such as Mt. Shibutsu, Mt. Hiuchi, Mt. Aizukoma, Mt. Tashiro, and Mt. Taishaku. In addition, Oze has been subjected to development crises repeatedly in the past; however, this invaluable nature is kept today by efforts of many people, and it is also known as “the origin of nature conservation” in Japan.

Naturally formed beauty created over the course of 80 million years. Lining 600m of the cave is what is said to be the greatest number and variety of stalactites in Asia. There’s a lot to see in Takine Goten, the largest hall in the cave, including the Tsuki no Sekai, which features the first light control system for stage productions ever introduced in a Japanese limestone cave. Enjoy this mysterious and impressive underground fantasy world.
