Ace Kosuke Hagino and teenage phenom Rikako Ikee were named to the provisional Japanese national team rosters for this summer's Pan Pacific Championships in Tokyo and Asian Games in Jakarta, the Japan Swimming Federation announced on Monday.

The country's governing body for the sport has selected 22 swimmers for the Pan Pacs, which take place every four years, and 23 for the Asian Games, based on the results from the national championships that wrapped up Sunday at Tatsumi International Swimming Center.

The full rosters will be completed after next month's Japan Open at Tatsumi.
