Shimeiso is a historic Japanese-style villa and garden in Shimabara, Nagasaki, that beautifully utilizes the region's abundant natural spring water. Built during the late Meiji to early Taisho eras by Dr. Motosan Ito, a local physician and municipal official, the villa was named "Shimeiso" because of its exceptional views in all four directions. The garden is fed by approximately 3,000 tons of fresh spring water daily, creating a crystal-clear pond where colorful koi fish swim gracefully. Surrounded by lush greenery, this site offers a deeply emotional and tranquil space where Japanese aesthetic sensibilities and the gifts of nature harmonize perfectly.
The history of Shimeiso dates back to the late Meiji and early Taisho periods. The original owner, Dr. Motosan Ito, was a prominent figure who served as a physician and a member of the Shimabara town council. Legend has it that a Zen monk was invited to design the garden during the early Showa era. The main building was officially designated as a Registered Tangible Cultural Property of Japan on April 25, 2014, while the garden itself was registered as a national monument in 2008. This estate remains a vital cultural heritage site that symbolizes the unique "water culture" of Shimabara.

The greatest draw is the architectural design of the villa, which is built to face the pond. The structure features an "Engawa" (veranda) that extends toward the water from the front and left side of the main room. This allows visitors to look down upon the garden from an elevated position, creating a seamless visual connection between the building and the landscape. The pond is adorned with four small islands, adding depth and texture to the scenery. Meticulous care is evident in the details, from the sand-covered pond bottom to the carefully placed stepping stones. The traditional architecture includes a single-story wooden structure (with some two-story sections) featuring classic tiled roofs and a "Hoke-zukuri" style gate.
Shimeiso offers a beautiful experience throughout the year. The garden is home to various plants such as Japanese black pine, maple trees, and moss, which change their appearance with the seasons. The sight of the clear spring water and the movement of the koi is particularly striking during the bright daylight hours. The facility is open from 9:00 AM to 6:00 PM, and there are no scheduled closing days.
Visitors can immerse themselves in the "Sukiya-zukuri" architectural style, enjoying the profound stillness of the garden. From the comfort of the tatami-matted rooms, you can observe the koi and the lush greenery, providing a sense of traditional Japanese relaxation. The exceptional clarity of the spring-fed pond is a unique highlight of this location.
Shimeiso is located in the part of Shimabara known as the "Town of Swimming Koi." The surrounding area features the Seirutei Tourism Exchange Center, where you can further explore local history and culture. It is a perfect stop on a sightseeing route centered around the region's famous spring water culture.
Please watch your step while walking through the garden, as there are areas with stone paths and sand. Comfortable walking shoes are highly recommended. Payment for admission is made in cash at the ticket booth at the entrance. Please note that professional photography (hiring a photographer) requires an additional fee. To maintain the peaceful atmosphere, please observe quiet manners and treat the historic structures with care.
