Otsuka-Sai Kato Ruins Park

Overview and Attractions

Otsuka-Sai Kato Ruins Park, located in Tsuzuki-ku, Yokohama, Kanagawa Prefecture, is a historical park that preserves the living sites of the mid-Yayoi period. The park is composed of two significant archaeological sites: the 'Otsuka Ruins,' representing a settlement, and the 'Sai Kato Ruins,' representing a burial area. Developed by the City of Yokohama to preserve and pass down cultural assets, this site is a crucial location for learning about Japan's ancient history. Within its vast grounds, you will find reconstructed facilities such as ancient dwellings and burial structures, offering a glimpse into the historical landscapes found in textbooks.

Historical and Cultural Background

The Otsuka and Sai Kato ruins are renowned as sites of life during the mid-Yayoi period. The Otsuka site is a remnant of a moated settlement where approximately 100 people are believed to have lived about 2,000 years ago. The surrounding moat served a defensive role against intruders. Meanwhile, the Sai Kato site served as the burial ground for the residents of Otsuka. It features distinctive graves known as 'Hokei Shuko-bo' (square-grooved graves), which provide insight into the burial culture and views on life and death of that era. These sites were preserved and developed as part of the cultural heritage preservation efforts during the development of Kohoku New Town.

Main Highlights

The park features various historical remains from different eras:

• *Otsuka Ruins Reconstructions**: Reconstructed pit dwellings (tateana-jukyo), raised-floor warehouses, and wooden bridges allow you to see exactly how people lived and what their structures looked like.
• *Sai Kato Burial Sites**: These include characteristic graves with low square earthen mounds and surrounding ditches. The site reproduces the state of the excavations and wooden coffins, allowing for a detailed observation of ancient burial forms.
• *Tsuzuki Minka-en**: This area features relocated traditional thatched-roof houses and stables built during the mid-to-late Edo period. It is a facility where you can feel the evolution of Japanese housing culture from the Yayoi period through to much later eras.

Seasonal Recommendations

The park is open year-round and offers different charms depending on the season.
