Japan Women vs South Korea Women: match prediction on 26 September 2026

Japan to win is the clear outcome here. The model puts them 11 points ahead, they have beaten South Korea in every meeting on record, and their defensive record is far tighter.

Japan have not lost a game since the tournament began. Five wins, 15 points, and a scoring margin of nearly 50 points per game. They beat Hong Kong 114-37, Kazakhstan 88-23, Philippines 89-67, Thailand 86-29 and Chinese Taipei 80-52. The defence has been exceptional, conceding just 208 points across five matches. That is an average of 41.6 points against per game, and it is the sort of consistency that wins championships.

South Korea are undefeated too. Five victories, 15 points, scoring 453 while giving up 299. They beat Malaysia 106-40, Mongolia 88-61, Chinese Taipei 73-59, Indonesia 101-59 and China 85-80. The win over China is the notable result, but the defensive numbers tell a different story. They have conceded 59.8 points per game on average, and that gap between attack and defence is where Japan's superiority shows.

The head-to-head record is dominated by Japan. Four meetings, four victories. The closest was 78-77 in August 2026, a single-point thriller. The others were 77-59, 81-58 and 67-62. Japan have won by an average margin of 13.5 points in those fixtures. South Korea have not managed a win in any format, and the pattern does not suggest a sudden reversal is coming.

The model expects Japan to score 67.7 points and South Korea 56.6. That is an 11.1-point margin, and it aligns with what the historical data shows. The draw probability sits at 0%, which is expected in basketball where ties go to extra time. The model does not account for injuries or tactical changes, but the underlying numbers are consistent with Japan's recent form.

A draw would be the only scenario that breaks this conclusion, and the model puts that at 0%. If South Korea can hold Japan to under 60 points while scoring 65 or more, the prediction fails. Given Japan's defensive record and their habit of closing games out, that is the unlikely path.
