Claim
Common onions were introduced to East Asia in the 19th century
Correction

This is too late. Sources record common onion cultivation in China centuries—possibly millennia—before the 19th century, so the statement is inaccurate for East Asia as a whole.

Full reasoning

The claim says East Asia received common onions only in the 19th century, but authoritative sources place onion cultivation in China much earlier. The International Society for Horticultural Science's abstract on onion production in China states that onion had "more than 700 years in record" in China. EBSCO's research overview goes further, saying records suggest the Chinese grew onions more than five thousand years ago. Because China is part of East Asia, these sources directly contradict the article's broad regional claim. A narrower statement about Japan in the 19th century may be supportable, but the article's wording about East Asia is incorrect.
