A Library Concealed Within the Landscape
Located within KURKKU FIELDS in Kisarazu, Japan, Library in the Earth was conceived as a place for people who cultivate the land on sunny days and immerse themselves in books when rain arrives. Positioned on a flat site above a valley once filled with construction debris, the project transforms an overlooked piece of land into a cultural destination rooted in ecological restoration. By embedding the architecture into the terrain, the design creates a powerful dialogue between knowledge, agriculture, and landscape.


Restoring the Valley Through Humble Architecture
The project sought to revive the lush valley leading toward the farmers’ beloved “Mother Pond,” a place regarded as a symbol of fertility and life. Instead of occupying valuable cultivated soil, the architecture is carefully tucked beneath the ground, allowing plants and microorganisms to flourish above it. This approach reflects a philosophy of coexistence rather than domination, where the building becomes part of the ecological cycle instead of interrupting it. The result is a quiet architectural statement that honors the earth as both a source of life and a place of collective memory.


▏Our wish was to make a small cleft in the earth and create a tranquil place suitable for farmers to rest. The cleft looks like a water drop when viewed from above. As you wander into the approach and pass through the plowed ground, a corridor of bookshelves appears. Architectural elements such as beams and columns have been eliminated, while the concrete void slabs cantilever out from the outer retaining walls and wing walls. The floor, walls, and ceiling all have an earthen finish and connect smoothly, and the lawn that has been planted up to the vertical edge of the slab hangs down lushly and gives the space a sense of dampness. This detail allows for the balance of irrigation and water retention to be adjusted according to the season.





▏The ceiling heights inside are determined by the slope of the ground, so there are areas with low ceilings and small hidden rooms that only children can enter. At the deepest part, there is a hall for storytelling. In the womb-like space that uplifts the lawned ground, folds of bookshelves surround the stepped seats, and books from the collections of farm workers and books for children line up. The 40mm thick vertical frames of the bookshelves extend overhead to support the space.


▏When a thin vertical beam supports the next one, and that vertical beam is also supported by its neighbor, a large space can be supported as a whole when the repetition makes a circle. At the end of the chain of reciprocal support, a social space arises that cannot be created by strong individuals alone. The top light at the center of the structure, which symbolizes the agricultural community of KURKKU FIELDS, frames a view that resembles the earth covered in blue sky and clouds. It is a library that thinks of the earth.
