In August, the Cultural Heritage Agency of the Netherlands (RCE) is joining forces with the Kyushu National Museum to conduct an exploratory research on the Dutch shipwreck Van Bosse. The research focuses on exploring opportunities for mapping the Van Bosse and providing accessibility to the wreck for local sports divers. The project is a continuation of existing cooperation with Japan in the field of maritime archeology within the framework of Dutch Shared Cultural Heritage policy. The site of this Dutch wreck is already protected locally. The ship was built in Germany, but registered by the Dutch owner in Rotterdam.
The ship Van Bosse was originally built in 1854 in Germany. The 665t big three master barque, which was employed by the Bonke & Co. Trading in Rotterdam was on its way from Shanghai to Singapore when it sank during a storm in 1857 at Tarama island, Okinawa prefecture. Luckily all 27 people on board survived, but before they could return to Batavia in the Dutch East Indies, people stayed several months in Okinawa and integrated into the local community.
The story of the sinking of the Van Bosse and the interaction of the people of Tarama with the crew of the ship are recorded in detail. It gives us a good insight into the history of the Ryukyu Kingdom and the relationship that it had with foreign powers at a time when the self-isolationism of Japan had just been lifted. It is striking that until few years ago nobody knew exactly what ship it was, although the story of the sinking of the ship was well known. We know it now, thanks to extensive research in Dutch archives.
The Van Bosse shipwreck is registered as a Village Historic Site (オ ラ ン ダ 船 遭難 の 地: Oranda-sen Sonan no Chi ~ Site of Dutch ship wreck). It lies on a reef at depths ranging from a few meters to about 30 meters. Over the years, an iron anchor was lifted, which is on display in a local museum, and several other finds such as a complete Lucas Bols gin bottle and some salvaged porcelain shards.
However, there’s more to be found. Despite the protected status of the ship an archeological significance assessment of the wreck site has not yet been made. This will take place this autumn and is having its official start now in August, with a first joint visit to the site. Ultimately this will lead to a management plan for the site in which all interests should be taken into account. The Van Bosse wreck is already dived regularly by sport divers. A local dive shop has voluntarily undertaken protection of the site. The local authorities are working on an active promotion. The aim is to use the wreck to attract more recreational divers to the island. But what measures are necessary to facilitate an intensive visit of sports divers? How, for example, can the remains underwater be protected while still visible and accessible to visitors? And there is need for more information about the site to allow divers to fully experience the wreck and its history when they are underwater.
In August Dr. Ikeda from the University of Okinawa, Dr. Jun Kimura of the Tokai University in Tokyo (with students), Randy Sasaki of the Kyushu National Museum and Martijn Manders (RCE) will officially start the project. In November, the Japanese partners will conduct follow-up research historical research in the Netherlands and Germany will be coordinated by the RCE.
Late August the World Archaeological Congress (WAC http://wac8.org/) will be held in Kyoto, Japan. As part of the Japanese - Dutch cooperation Martijn Manders and Yoshihi Akashi will represent the Fukuoka prefecture and chair the session 'Global Perspectives on Underwater Cultural Heritage Management’. The presentations will elaborate on universal values of the underwater cultural heritage management, what needs to be improved in management and the way countries can cooperate in the protection of underwater cultural heritage. This fits exactly with the way the research on the Van Bosse shipwreck is implemented: a collaboration between various parties in the country where the ship sank, Japan, and the country of origin, the Netherlands.
