Sannai-Maruyama Site T-Shirt | Jomon Archaeology Design | Japanese History Unisex Tee

About This Product

An original T-shirt by Hasegawa Shizen Kobo inspired by the Sannai-Maruyama Site in Aomori City, Aomori Prefecture.

The Sannai-Maruyama Site is a large-scale settlement site dating from the Early to Middle Jomon period and is known as one of Japan’s most important Jomon archaeological sites.

This T-shirt prominently features the large post-supported structure that symbolizes the Sannai-Maruyama Site. The towering wooden posts set against the blue sky evoke the daily life of the Jomon people and the remarkable level of architectural skill they possessed at the time.

The Sannai-Maruyama Site is also one of the component sites of the Jomon Prehistoric Sites in Northern Japan, which were inscribed on the UNESCO World Heritage List in 2021.

This shirt is recommended not only for those interested in Jomon culture, archaeology, and Japanese history, but also for people who enjoy visiting archaeological sites, museums, and historical destinations.

About the Design

The front prominently features the large post-supported structure that represents the Sannai-Maruyama Site.

The strong vertical wooden posts rising from the ground toward the sky are contrasted with the clear blue background, creating a design that brings the architecture and daily life of the Jomon period closer to the viewer.

Rather than presenting the site only as a historical artifact, this design is intended to serve as an invitation to imagine the lives and skills of the Jomon people.

It also makes a unique gift for anyone interested in Japanese culture or the Jomon period, and is a memorable souvenir of a trip to Aomori or a visit to archaeological sites.
