During the 1930s and 1940s, the Japanese government linked eugenics to nationalism by arguing that Japan's national strength depended on the biological quality of its citizens.
NOT BSTOTAL BS
HARDLY BS — Verdict: Mostly True

The Short Version
The historical record supports the core point. Japanese officials and lawmakers in the late 1930s and 1940s explicitly connected eugenic ideas to national power, arguing that the population's hereditary and physical quality affected the nation's strength. The wording is somewhat broad, though, because wartime nationalism also drew on other themes besides biology.
Caveats
The clearest documentary support comes from the 1940 National Eugenic Law and surrounding debates, so the claim is strongest for that policy context rather than every official statement across both decades.
"Depended" slightly overstates the evidence if read as exclusivity; biological quality was presented as one important basis of national strength, not the only one.
Ideological rhetoric and practical implementation were not identical; the state's eugenic-nationalist framing was broader than the actual scale of enforcement.
