The main office building was completed before Nagashima Aisei-en opened, and it was used from 1930 to 1996. The land occupied by staff and patients or survivors was strictly divided until mid-1955, and therefore residents were not allowed to enter the main office building because it was in the staff area. The main office building has also been used to lead Hansen's disease policy and as a base for the transmission of information.
In 2003, the interior of the main office building was repaired and it reopened as the historical museum of Nagashima Aisei-en. It now plays a role in relating the history of Hansen's Disease and Aisei-en. The historical museum also urges visitors to create an inclusive and welcoming society for all, where there is no prejudice and no discrimination.
- The Nagashima Aisei-en historical museum is run by a management committee composed of the Residents' Association of Nagashima Aisei-en, the Japan Society for the Promotion of Science, and the volunteer group Yui no kai.
- When you visit the Aisei-en historical museum, we offer guided tours led by volunteers and curators to help you gain a greater understanding.
- In the Nagashima Aisei-en museum, the topics related to Hanse's Disease are separated into two parts. The first floor explains historical and current problems surrounding Hansen's disease, and the second floor relates the feelings of the residents. If it is your first visit and time is limited, we encourage you to spend time on the first floor exhibition rooms.
