Manazuru is a small harbor town located in southern Tokyo Bay. The harbor is characterized by elements specific to its use, which, though purely pragmatic in design, contribute to its unique appearance. While these elements are static, the fishermen, day visitors, and their interactions with the space add a dynamic layer to the harbor's character. The project's approach is to formalize the fishing legacy and tradition in a new design that supplements, rather than replaces, the existing structures.

The methodology of the analysis focused primarily on photographic and site-specific examination of the harbor area, as well as direct engagement with users through conversations and interviews. The goal is to develop a sustainable approach that preserves the cultural significance of fishing for Japan's coast, ensuring that the harbor's legacy is passed on to future generations. Additionally, this approach aims to address the stagnating population figures in rural areas by preserving and enhancing an important cultural asset.

The Longhouse is situated on the south side of the main harbor edge and marks the transition from the public fishing area to the industrial zone. The harbor's users converge not only in the harbor itself but also within the Longhouse. Fishermen can relax in a break room, while day guests and rod fishers can repair their gear next door. All spaces in the Longhouse can be connected with movable partition doors, similar to traditional Shoji screens. The general structure is divided into a public working area that opens via a roofed outdoor space (akin to an Engawa) toward the water, and an enclosed section with restrooms and showers on the southern, more private side. The front desk, which houses the harbor master, as well as the workshop area, are flat, while the closed side follows the slope of the harbor basin.

The Locker is centrally located among the new structures. It is a multifunctional space designed for storing equipment during the day or for market vendors to keep their personal belongings while selling at the weekly harbor market. The roof provides shelter from the rain and serves as a meeting point for visitors. The second layer of enclosure is the locker room itself, a fully closed, single-story pavilion. The roof can be accessed via stairs on its facade.

The new bus stop marks the entry point to the harbor by land. It symbolizes the open and welcoming character of the newly formed harbor ecosystem.
