In their first tournament since qualifying for the 2018/19 HSBC World Rugby Women’s Sevens Series, China booked their spot in the quarter-finals.
Despite losing their opening match to Australia 33-5, a narrow 19-17 defeat so Spain and an impressive 24-12 win over Ireland now means they face New Zealand on day two.
For hosts Japan it was a disappointing day with three defeats to New Zealand, France and USA.
They face the USA for a second successive time in the Challenge Trophy semi-finals on day two.
For China, however, it’s a match with New Zealand after their win over Ireland. Having recently qualified for the main series next season, they showed they can compete with the best.
Hot off the back of her hat-trick in the final against South Africa in Hong Kong Keyi Chen scored twice to help secure the win, having earlier dotted down against Spain.
Despite trailing 19-0 at half-time China showed great character to come within two points of a draw, with a chance to draw level from Chen’s try unsuccessful.
Japan ended their day with a 45-17 defeat to the USA. Despite trailing 45-7, two late tries from Mifuyu Koide and Raichielmiyo Baitvakalolo gave the home crowd something to cheer.
