Malaysia won the opening match in the nations' top-of-the-table tie, as Aaron Chia and Soh Wooi Yik won the men's doubles in three games.

The defeat was the first tasted by Japan so far in Finland, but back-to-back singles wins soon put hem back on top.

Akane Yamaguchi - a former junior world champion and Youth Olympic Games runner-up - beat Kisona Selvaduray 21-14, 21-14, and reigning men's world champion Kento Momota then knocked off Lee Zii Jia 21-18, 21-10.

Lee, the reigning All England Open champion who beat Momota at that tournament, represents one of the finest players Momota has beaten since suffering facial injuries and vision problems after a vehicular accident in Malaysia in 2021.

A straight-games win for women's doubles pair Nami Matsuyama and Chiharu Shida gave Japan the win, and a mixed doubles success meant it ended 4-1 in their favour.

England whitewashed Egypt in the group's other match, finishing third.

There were two more whitewashes in Group B as South Korea ensured they would finfish top of the pile.

Heo Kwang-hee beating world number four Chou Tien-chen in the men's singles represented the pick of South Korea's five wins versus Chinese Taipei.

Heo - who beat Momota at the Tokyo 2020 Olympics - triumphed 15-21, 21-11, 21-17.

Germany smashed Tahiti without dropping a game in the group's other match.

The quarter-final draw was made after the final match Energia Areena, and Japan's reward for topping their group is a last-eight tie with Chinese Taipei.

South Korea will play Thailand, defending champions China face Denmark in the opening match and Malaysia are up against Indonesia.
