Mount Kanpuzan is a volcano standing approximately 355 meters high, located near the center of the Oga Peninsula in Akita Prefecture. Its most striking feature is the entire mountain being covered in a lush, green carpet of grass, creating a soft, undulating landscape that looks like a natural velvet rug. At the summit, a unique rotating observatory allows visitors to experience a seamless 360-degree panoramic view. To the east, you can see the Hachirogata reclaimed land; to the south, the sacred Mount Chokai; to the north, the UNESCO World Heritage Shirakami-Sanchi mountains; and to the west, the vast Sea of Japan and the Nyudozaki Lighthouse. It is a premier spot to experience the rich natural beauty of Akita in one glance.
The formation of Mount Kanpuzan began with volcanic activity approximately 30,000 years ago. The gentle slopes seen today were shaped by layers of andesite lava. The local area is also known for 'Oga Stone,' a type of andesite used for centuries in local coastal protection, garden stones, and gravestones, deeply connecting the geological heritage to the local way of life. The landscape also preserves traces of its volcanic origins, including the remnants of the first and second craters and the Tsumorei Pass crater, offering a glimpse into the geological history of the region.

The 'Rotating Observatory' at the summit is the main attraction, slowly rotating to complete a full circle in about 13 minutes. Visitors can enjoy the view while sitting or standing inside the sheltered facility. Surrounding the observatory are spots to observe unique geological formations and beautiful grasslands. There are also smaller observation points scattered along the mountainside, offering different perspectives of the landscape. The ever-changing scenery of the grasslands and the majestic silhouette of Mount Chokai continue to fascinate visitors throughout the year.
While Mount Kanpuzan is beautiful in every season, certain times offer special delights. From spring to early summer, the area is perfect for plant observation as rare flowers like the Pasqueflower (Okinagusa) and Azumagik become visible. From summer to autumn, the landscape is a sea of vibrant green, transitioning to swaying silver grass in the autumn. On clear days, the visibility is exceptional, providing sharp views of the Sea of Japan and Mount Chokai. Please note that the observatory is closed during the winter season (mid-December to early March).

There are many ways to enjoy the natural beauty of Mount Kanpuzan. It is an ideal destination for a scenic drive, as the road leads directly near the summit. For those seeking more physical engagement, well-maintained trekking courses are available, such as the route from the small observation points to the summit area (approx. 6km, taking about 2.5 hours). Occasionally, paragliding activities are held, allowing you to experience the breathtaking views from the sky. After your descent, you can enjoy local Akita specialties like Inaniwa Udon or Hinai Jidori Chicken Oyako-don at the summit restaurant while soaking in the view.
The Oga Peninsula offers many other fascinating spots near Mount Kanpuzan. You can visit the 'Namahage Museum' to learn about the traditional culture of Oga, explore the beautiful coastline of Nyudozaki, or relax in the Oga Onsen hot spring villages. Combining these with a visit to the mountain allows for a rich travel itinerary of nature, history, and relaxation. Local roadside stations (Michi-no-Eki) are also useful for breaks and gathering information during your drive.

If you plan to go trekking, sturdy walking shoes and comfortable clothing are highly recommended. Since the summit area can become quite windy, it is wise to bring a light jacket or windbreaker. When using the restaurant or shop at the observatory, please have cash or a credit card ready for a smooth transaction. While photography of the landscape is encouraged, please be mindful of your surroundings and follow local etiquette to ensure a pleasant experience for everyone.
