Oiso Shiroyama Park is built on gentle hills, offering sweeping views from its heights over the Sagami Bay, Izu Peninsula, Hakone mountains, and even Mount Fuji. It’s ideal for leisurely strolls. Visitors can relax with a cup of matcha served at the Shiroyama-an teahouse, modeled after the national treasure Jo-an teahouse. In autumn, vivid red maple leaves stand out against the greenery. From November 27 to 29, the 'Maple Light-Up 2026' event creates a magical illuminated atmosphere.
