Shared Samples

Population Description

These cell lines and DNA samples were prepared from blood samples collected from people living in the Tokyo metropolitan area. All of the samples are from unrelated individuals.

Since it is considered culturally insensitive in Japan to inquire specifically about a person's ancestral origins, prospective donors were simply told that the general aim was to include samples from people whose grandparents were all from Japan. The samples were collected from people who lived in (or whose ancestors presumably came from) many different parts of Japan. 

Referring to Populations

It is important to refer to this community as "Japanese in Tokyo, Japan" when describing these samples in articles or presentations. The population should not be described merely as "Asian" or as "East Asian", terms that encompass many communities.

The full population descriptor is Japanese in Tokyo, Japan and the abbreviation is JPT.

Additional guidance about how to refer to the populations can be found at Guidelines for Referring to the Populations in Publications and Presentations.
