2018 WIHA Women's World Cup (Eastern Manifest Destiny)

The 2018 WIHA Women's World Cup was the 33rd WIHA Women's World Cup, the tournament for the women's ice hockey world championship, which took place at several venues across the Republic of Korea and the Republic of China. Japan won the tournament, the country's second title. It was the first WIHA cup to take place in Korea, and the second in China.

Thirty-one national teams advanced through qualification competitions to join the host nation in the final tournament. A total of 64 matches were played in 7 venues in 7 cities across the Republic of Korea and the Republic of China. This is the first time in a WIHA competition that had two host countries, with the cities and venues split between 4 Korean cities and 3 Chinese cities. The championship attracted over 3.8 million people and received 1.92 million visitors from 91 countries.

Of the WHC-winning teams, six of the eight—Norway, Sweden, Japan, Russia, Canada, and Finland—qualified for the tournament. Finland, the title holders, were eliminated in the knock-out rounds. Norway was eliminated in the knockout rounds as well. Russia, Canada, and Sweden got second, third, and fourth places, respectively. In the final, Japan defeated Russia 1-0 to win the tournament and secure the country's second title.

Host Selection
In August 2013, WIHA announced that the tournament will be run as a co-hosted tournament. Korea-China, Germany-France, Ukraine-Russia, and Greece-Turkey officially announced their bids. Greece-Turkey dropped out after the election of a new Turkish President who refused to pay to maintain ice rinks. Ukraine-Russia dropped out following a financial crisis in Ukraine. This left the Korea-China and Germany-France pairings in the process. Korea-China were chosen as the co-hosts on 3 May 2015 after narrowly beating the Germany-France pairing by 2 points.

Qualifications
Following qualification matches played between June 2015 and December 2017, the following 32 teams qualified for the tournament. All but 3 of the teams were returning participants from the 2016 WIHA Women's World Cup.
