Answer
Brief Explanations:
In the late 1800s, Western imperial powers like Britain, France, etc. had significant control over large parts of Asia. Japan, fearing being colonized or dominated like other Asian countries, decided to quickly build up its military as part of the Meiji - Restoration modernization efforts to ensure its sovereignty and compete in the imperialist - driven international arena. The other options are not the main reasons for Japan's military build - up. The idea of colonizing eastern Russia came later, Perry's visit in the 1850s was more of an initial shock to open Japan rather than the direct cause of the late 1800s military build - up, and Korea was not a strong military power at that time relative to Western powers.
Answer:
Western imperial powers controlled large parts of Asia.
