Oiso Shiroyama Park
9 min di letturaOverview & Charm
Oiso Shiroyama Park, located in Oiso Town, Nakau County, Kanagawa Prefecture, is a stunning park where history and nature blend seamlessly. Developed on the former site of the Mitsui family's villa and the residence of Shigeru Yoshida, the park offers a vast landscape of traditional Japanese architectural styles and exquisite gardens. It provides a serene atmosphere where visitors can escape the hustle and bustle of daily life and enjoy a peaceful stroll through a lush, green environment.
Historical & Cultural Background
The history of this park is deeply rooted in the prestigious residences that once stood here. The grounds are divided into the area utilizing the former Mitsui family villa site and the area of the former residence of Shigeru Yoshida, a significant figure in Japanese political history. Local lore even suggests that a historical site called "Koiso Castle" once existed in this vicinity, adding a layer of historical depth to the land. Today, these grand estates have been preserved as a public park, allowing many to touch upon both history and nature in one place.

Main Highlights
The park is primarily composed of two distinct areas: the "Former Mitsui Villa Area" on the mountain side and the "Former Yoshida Residence Area" on the sea side. In the Mitsui area, you can experience cultural depth through the "Joyaman" tea house, the Kitakura Gallery, and the Oiso Town Local History Museum. An observation deck also offers beautiful views of the surrounding scenery. Meanwhile, the Yoshida area features a statue of the statesman Shigeru Yoshida, his former residence, and a breathtaking Japanese garden. Each area offers a unique charm through its distinct architecture and landscapes.
Seasonal Recommendations & Best Times to Visit
The park is rich with the changing colors of the seasons. From spring to summer, the vibrant greenery is particularly beautiful and ideal for walking. The rose garden is another highlight, offering seasonal blooms that delight visitors. Depending on the time of day, the way light hits the gardens changes—we recommend a morning stroll to enjoy the crisp, fresh air, or an afternoon visit to soak in the soft, warm sunlight reflecting off the traditional structures.

Activities & Experiences
Beyond simple walks, the park offers profound cultural experiences. You can feel the essence of traditional Japanese space while observing historic architecture like the "Joyaman" tea house. The exhibition facilities also provide a way to connect with local history and culture. Whether you are observing seasonal plants or exploring the historical buildings, the park invites a quiet, contemplative journey through time.
Surrounding Area
The area surrounding the park is dotted with facilities that allow for a deeper understanding of Oiso's history, such as the Oiso Town Local History Museum. Exploring the nearby streets, which retain a nostalgic atmosphere from the Meiji era, is highly recommended alongside the gentle, coastal vibes of the Shonan region.
