Switzerland and the Czech Republic both made winning starts at the International Ice Hockey Federation (IIHF) Women's World Championship in Denmark.

The Swiss, who like the rest of Group A are guaranteed a quarter-final berth so are playing for seeding in the knockout rounds, beat Japan 3-1 at Herning's KVIK Hockey Arena.

Lara Stalder and Alina Muller both scored in the second quarter, assisting each other's goals, as Switzerland took charge of the match.

Lena Marie Lutz added a third before Akane Shiga scored a consolation for Japan.

Following yesterday's 10-0 defeat versus the United States, Japan now have two losses from two and prop up Group A.

In Group B, where five teams are battling for three quarter-final spots, the Czechs blew past Hungary 7-1.

Six different players scored for the Czech Republic at Scanel Hockey Arena in Frederikshavn, with Adela Sapovalivova bagging a brace.

The Czech Republic are now top of Group B, while Hungary fall to third with one win and one loss.

Four games are scheduled tomorrow at the IIHF Women's World Championship, including Switzerland facing reigning world and Olympic champions Canada.
