Two Okinawans will participate in the tennis competition at the Tokyo Paralympics, which kicks off on Aug. 23 — one as an umpire and the other as a staffer who strings athletes' rackets.

Kazuki Omine, 54, chairman of the Okinawa prefectural tennis association’s umpire committee, will serve as a line umpire for wheelchair tennis games. Masaki Tokumura, 48, who works at a local tennis store, is the official stringer for the Tokyo Games tennis tournament.

Both have big roles to play, but neither is too overwhelmed, saying they will carry out their duties as expected.
