The Digital Natural History Museum of Hiroshima University is a cluster of web sites for dissemination and practical use of educational and research resources for lifelong learning as well as school education in collaboration with laboratories and centers of Hiroshima University, Japan. The museum site includes contents on biological, environmental and earth sciences, mainly in Japanese with some English, especially bryophytes and the world heritage listed Itsukushima (Miyajima) Island, Hiroshima Prefecture, Japan. Online site access has increased since 2015. The museum site is now transferring the html based system to the MediaWiki system which is a free and open-source wiki software. For regional studies we plan to expand significantly the content of available resources to enable greater use and ease of access through information and communication technology (ICT).
