Takagi was brought in to replace injured Yuki Abe of Urawa Reds just a few hours prior to the departure for Muscat.

Abe played in the first match of the Kirin Cup on May 24, a warm-up for this month's four-game qualifying series.

But the Reds defender has been suffering with ankle injuries and has trained separately from the rest of the squad for the last few days.

The 27-year-old Takagi has been a regular defender for his J.League club since 2005, playing in 112 matches for the past three-and-a-half seasons.

Japan defeated Oman 3-0 in Yokohama on Monday and play the return fixture on Saturday before travelling to Bangkok for the June 14 game with Thailand.
