Q: The German Empire had primarily economic interests in Micronesia. The Japanese interests were in land. Despite the Marshalls' small area and few resources, the absorption of the territory by Japan would to some extent alleviate Japan's problem of an increasing population with a diminishing amount of available land to house it. During its years of colonial rule, Japan moved more than 1,000 Japanese to the Marshall Islands although they never outnumbered the indigenous peoples as they did in the Mariana Islands and Palau.
A:
About how many Japanese emigrated to the Marshalls when it was a Japanese colony?
