Third seed Kasumi Ishikawa went out in the first round of the Japan Open on Friday, losing 4-1 to China's Wang Manyu in the women's singles.
Ishikawa, who lost in the quarterfinals at the world championships to top-ranked Ding Ning last month, came up short against Wang, who had beaten her in straight games when they met in February at the Qatar Open.
Ishikawa won the first game 11-6, but her backhands began to falter in fast rallies in the face of an aggressive Wang and she missed a serve to hand her foe a 2-1 lead.
