The final match saw Indonesia and Japan duel for a fourth consecutive time in the Uber Cup final, this time with Indonesia going all out to defend its title.[1] Japan won the first singles when Saori Kondo of Japan, who reached the finals of the All England Open two months prior, defeated Indonesia's Ivana Lie 11–3, 11–3. Both teams were at 1–1 when Verawaty Wiharjo of Indonesia beat former All England champion Hiroe Yuki 11–3, 11–6. The third singles went Japan's way as Atsuko Tokuda won against Tjan So Gwan 11–5, 11–4 and gained Japan a 3–1 lead against their opponents.
Indonesia's title was in jeopardy when Imelda Wiguna and Verawaty Wiharjo trailed one game against Emiko Ueno and Yoshiko Yonekura. Wiguna and Wiharjo then came back to defeat their opponents in the next two sets, giving the team hope. The second doubles match saw Indonesia's Uber Cup reign come to an end as Regina Masli and Theresia Widiastuti lost 11–15, 12–15 to Mikiko Takada and Atsuko Tokuda. At 4–2, Japan regained the Uber Cup once again. Japan won the last doubles to finish the tie 5–2.
