Alley from Kosojima
9 min readOverview & Highlights
Alley from Kosojima is a scenic park located in Kure City, Hiroshima Prefecture, facing the beautiful Kure Bay. The most striking feature of this location is the proximity to the sea, where you can observe Japan Maritime Self-Defense Force (JMSDF) submarines and destroyers from the Kure Base anchored just a short distance away. The surrounding landscape is characterized by the nostalgic atmosphere of the former Naval Arsenal, with its iconic red-brick buildings standing as a testament to the past. The beautiful contrast between the lush greenery and the weathered brickwork creates a serene space where you can relax and immerse yourself in a sense of history.
History & Cultural Background
The name of this location is a combination of the English word 'Alley' and 'Karaskojima,' a small island that once existed in Kure Bay. This area has a deep-rooted history; during the Taisho era, the surrounding area was reclaimed to serve as a torpedo training ground. Furthermore, this region holds significant historical weight as the area where the legendary battleship Yamato was constructed in a nearby dock. The red-brick structures scattered throughout the park serve as a living museum, preserving the architectural legacy of Japan's modern shipbuilding and naval era.

Major Attractions
At Alley from Kosojima, visitors can enjoy a variety of views that blend nature with human history. One of the most exceptional experiences—one of a kind in the world—is the ability to observe JMSDF vessels, such as submarines and destroyers, at such close range. You can also see historical structures like the old torpedo unloading cranes, providing a visual connection to the history of shipbuilding. The combination of the red-brick buildings and the verdant paths makes this an ideal location for photography enthusiasts looking to capture the essence of a maritime town.
Recommended Times & Seasons
The park reveals different charms depending on when you visit. A particularly striking moment is during sunrise or sunset, when you might witness the ceremonial hoisting or lowering of national and JMSDF flags on the vessels. Seeing the flags flutter in the sea breeze against the backdrop of the changing sky is a truly memorable sight. Because the light interacts beautifully with the red-brick buildings and the natural scenery, visiting at different times of the day is highly recommended to see the landscape in a new light.

Activities & Experiences
Simply strolling through this historic landscape is an activity in itself. Walking along the 'Alley' surrounded by greenery and brick, you can feel the sea breeze and the breath of history. For those interested in maritime engineering, observing the docked submarines, destroyers, and vintage cranes offers a profound way to learn about Japan's naval technological evolution. It is a perfect destination for a quiet walk, meditation, or a slow-paced exploration of the scenery.
