Ishikawa overcame Turkey's Hu Melek in the women's singles final in convincing fashion.

Both players reached the final in dramatic style with respective seven game victories against Cheng I-Ching of Chinese Taipei and German Han Ying respectively, but there was to be no such nail-biting drama in the final as Ishikawa stormed to a fairly comfortable win.

The only previous meeting between the two took place eight years ago in the under-21 competition of the 2008 TMS Open in Singapore which Hu won.

Ishikawa was keen to make amends and started brightly to win the opening three games 12-10, 11-4, 11-6.

Hu extended the match by winning the fourth 13-11, but it would be Ishikawa who prevailed as she clinched the title by winning the fifth and decisive game 11-5.

"I’m very happy," said the Japanese player.

"Before the Olympic Games I trained for a long time so afterwards I took some time off to rest and relax.

"Now I have been training for a full month and this is my first tournament since then.

"I was really fast today and with a good combination of serve and attack I managed to win this match."

Oshima doubled his country's tally for the day as he overcame the home crowd to beat Sweden's Mattias Karlsson in the men's singles final. 

The 15th seed secured his second World Tour men’s singles title after he prevailed 11-8, 7-11, 11-8, 7-11, 11-8, 13-11.

Oshima took an early lead in the final after a positive showing in the opening game but, roared on by the crowd, Karlsson levelled the match at 1-1.

The Japanese player then reclaimed a one game advantage, only for Karlsson to once again draw the scores level in game four.

With the match all-square at two games apiece in the final, Oshima went on to claim the fifth.

The Swedish spectators were still confident of Karlsson replying, especially after seeing him race into a 9-5 lead in game six.

However, there would be no seventh game required to find a winner as Oshima made a fantastic recovery to break Swedish hearts and win the sixth game 13-11.

In the men's doubles final, Brazil’s Hugo Calderano and Gustavo Tsuboi made history as they defeated the French combination of Antoine Hachard and Stéphane Ouaiche 12-10, 12-10, 11-7.

It is the first time a Brazilian pair or a Brazilian player has won an ITTF World Tour men’s doubles title in what is now 285 men’s doubles events.

Chinese Taipei’s Cheng and Lee I-Chen, the tournament's third seeds, won the women's doubles crown after they overcame South Korea’s Jeon Jihee and Yang Haeun, the top seeds, 9-11, 11-8, 11-13, 11-5, 11-7.
