Guida
The Tapu Kopu Observatory is a scenic viewpoint located in Mikasa City, Hokkaido, offering an expansive view of the Ishikari Plain. Situated at the foot of Mount Tapu (Tapu Kopu) at an elevation of approximately 144m, the site allows visitors to witness the dramatic changes in local topography and geological layers. This location holds significant historical weight; during the Meiji era, many influential figures visited this spot to plan the development of the region. As part of the Mikasa Geopark, it is a unique facility where natural geological beauty meets historical context.
The spirit of the Meiji-era pioneers lives on in this landscape. The name 'Tapu Kopu' is derived from the Ainu language, meaning 'the round mountain at the top.' The name was bestowed in 1881 by Watanabe Koreki, the first warden of the Sorachi Shisetsu. During the pioneering era, prominent figures such as Buneemon Enomoto, Yamagata Aritomo, and Yamada Akikoshi visited this area to survey the land and establish bases for critical development projects, including the Horonai Railway. This site is not just a scenic spot, but a stage for the modernization of Hokkaido.
The greatest attraction is the observation of the terrain shaped by the Ishikari Lowland Eastern Margin Fault. Visitors can observe the ongoing movement of the Earth's crust through the landscape below. Another key feature is the 'Iwamizawa Layer,' a hard mudstone/shale formation. Formed at the bottom of the sea approximately 8 million years ago, this layer is more resistant to erosion than surrounding strata, maintaining its distinct shape through wind and rain. This unique topography is a precious asset of the Geopark.
The scenery changes beautifully with the seasons. We highly recommend visiting between May and October, when the snow has melted and the greenery is lush. Summer offers a stunning contrast between the green earth and blue sky, while autumn brings vibrant colors to the surroundings. Please note that the area is closed during the winter season (November to April). For the best experience, visit during daylight hours to enjoy an unobstructed view of the Ishikari Plain.
Here, you can experience 'Geo-tourism,' learning about the origins of the Earth. By observing the overlapping geological layers and fault-driven topography, you can feel the dynamism of the planet. Additionally, the surrounding area is known for grape cultivation, allowing you to see how local agriculture is deeply connected to the unique terrain and climate. It is a perfect place to reflect on the future that the pioneers once envisioned while gazing at the horizon.
The foot of Mount Tapu is home to grape-growing areas, including some of Japan's first licensed wineries. The Mikasa area is rich with geological discoveries, such as the 'Oiwake-Minebe Layer,' which preserves the memory of the sea from about 5 million years ago, including fossilized shells. The entire Mikasa region is a treasure trove of history and geological science.
We recommend wearing comfortable walking shoes, as you may be observing natural terrain. Since weather can change rapidly, bringing a light jacket or rain gear is advisable. To protect the natural environment and historical heritage, please strictly follow local rules: do not enter private property (such as vineyards) and ensure you take all your trash home with you. Photography is permitted for enjoying the scenery.
