The Kaiten Memorial Museum is located on Otsushima Island in Shunan City, Yamaguchi Prefecture. It serves as a memorial to the history of the 'Kaiten' human torpedo. The museum is built upon the historical context of this area serving as the Otsushima Base, where Kaiten training and launches took place. It houses precious artifacts, including the personal belongings of the crew, to preserve their memory. More than just a historical display, this facility offers a space to reflect deeply on the meaning of peace through the stories and spirits of those who served.
The origins of this museum date back to a 1962 meeting in Tokyo involving those connected to the Kaiten program. To preserve the spirit and history of the crew, a foundation was established in Shunan City to collect and display their personal effects. The museum was completed in 1968, and following subsequent fundraising efforts for expansion and maintenance, it was renovated into its current form in 1998. The items on display serve as vital cultural heritage, conveying the harsh realities of the era and the enduring hope for peace to future generations.

The museum houses approximately 1,300 precious artifacts. Key highlights include portraits of the crew and technicians, military uniforms, and various documents that illustrate their daily lives and historical context. A detailed diorama recreates the base, allowing visitors to visually understand the island's layout and the operations of the time. Additionally, an audiovisual corner provides a deeper learning experience through footage of former crew members discussing the 'Kaiten.' At the entrance, stone monuments inscribed with the names of the Kaiten martyrs create a solemn and respectful atmosphere.
As a place for quiet reflection and learning, a calm visit is recommended. The spring season, from March to April, is particularly beautiful as the surrounding nature begins to bloom, enhancing the experience of visiting the island. While the exhibits remain constant year-round, the weight of the history is felt regardless of the season. Please note that access to Otsushima requires a boat; it is essential to check the weather and ferry schedules in advance to ensure a smooth trip.
The primary activity here is 'learning' through historical observation. By studying the dioramas, you can gain a three-dimensional understanding of the base's structure and the island's topography. The audiovisual section offers a more immersive experience, bringing the atmosphere and voices of the past to life in a way that text and photos cannot. Engaging with the testimonies of these historical figures provides a profound opportunity to contemplate the preciousness of peace.
Otsushima Island, where the museum is located, is a quiet island with a significant historical background. The surrounding natural environment is very peaceful, allowing visitors to enjoy the scenic island landscapes during their historical exploration. There are areas nearby that still retain the traces of the former training base, making it possible to explore the local history within its natural context.
Please observe museum etiquette by maintaining a quiet and respectful demeanor. Since you will be traveling around the island, comfortable walking shoes are highly recommended. Regarding payment, please prepare cash (JPY) for the admission fee, as card payments may not be available. Because the exhibits include very delicate historical materials, please follow local instructions regarding photography. As access to Otsushima depends on boat-based transportation, please build extra time into your schedule to account for potential weather-related cancellations.
