The Kazakhs completed their triumph with a 49-17 win on their final game against Japan, following on from a 68-0 midweek win over Singapore, and a somewhat tighter 13-10 opening with over Hong Kong, who surprised many by finishing the tournament in second place - their best-ever performance - after beating Singapore 53-5 earlier in the day.
Hosts Hong Kong, who started the tournament as the fourth seeds, proved far too strong for Singapore dotting down nine tries in a one-sided rout. Hat-tricks from flyhalf Rose Fong and winger Natasha Olsen-Thorne propelled the home team to victory.
"I'm pretty happy and we are getting closer to where we want to be, but as a coach, you always want more from the players," said Hong Kong coach Chris Garvey. "Today was the closest that we have been to getting where I want this group to be. Credit to the girls, two of whom got hat-tricks and showed a couple of individual moments of brilliance, but the team effort has allowed those individuals to shine,"
Garvey and Hong Kong will look back and reflect on the narrow loss to Kazakhstan in their opener which in the end prevented them from being crowned Asian champions.
"Overall I'm very pleased. If we are being honest with ourselves we never thought we would get anything out of the Kazakhstan match and we thought the Japan match would be extremely tough but the girls have surpassed their own expectation.We set out to get third place but finished runners-up which is fantastic," Garvey added.
Hong Kong captain Christy Cheng Ka-chi added: "This tournament has given us a lot of confidence and we can see ourselves capable of being Asia No.1 in the future."
Kazakhstan's nine-try performance was far more one-sided than anyone expected a week ago, but Japan - perhaps reflecting a prioritisation of sevens since their failure to qualify for the WRWC last season - had a very disappointing week, though they did have, in the shape of Mami Okada, the tournament's leading scorer.
Kazakhstan's strength, on the other hand, seems to have been to have in-form players across the field. Though Anna Yakovleva remains the big name of Kazakh rugby, the glory was shared with a remarkable 13 of their players appearing on the scoresheet over the week.
