U.S. Policies Toward Japan Before World War I

Pre-WWI U.S.–Japan relations were broadly cooperative, shaped by shared Pacific interests.

Key Policies & Agreements

1. Open Door Policy (1899/1900): Equal commercial access in China for all powers—including Japan.
2. Treaty of Portsmouth (1905): TR mediated end of Russo-Japanese War; recognized Japan’s regional primacy.
3. Gentlemen’s Agreement (1907): Japan voluntarily limited labor emigration to US; eased anti-Japanese tension on West Coast.
4. Root–Takahira Agreement (1908): Mutual respect for Pacific possessions; reaffirmed Open Door in China.
5. Immigration Act of 1907: Bilateral provisions on Japanese immigration (less exclusionary than later 1924 Act).
6. Trade: Growing US exports (cotton, machinery, autos) to Japan.
7. Cultural/Educational Exchange: Visits by leaders (e.g., Taft 1905); student flows.

Overall: pragmatic accommodation of Japan’s rise, avoiding conflict while protecting US commercial access in China.
