Japanese female players defeated the Iranian women 3-0 (25-18, 25-16, 25-22).
Team Melli are scheduled to play India on Thursday.
“I am satisfied with the ways my team played but we could have won the third set,” Iran coach Fatemeh Rashidi said.
“From now on, we just concentrate on the India match because we want to secure our place in the Top eight,” she added.
Teams are pitted against one another in the pool round-robin preliminaries, with only the top two teams from each pool advancing to the Top 8.
The 22nd edition of the continent’s biggest women’s volleyball tournament kicked off on Aug. 30 and will run until Sept. 6 at 5,000-seater Chartchai Hall and The Mall Korat’s MCC Hall in Nakhon Ratchasima, Thailand.
