Teenage striker Chuba Akpom came off the bench to score the winner as Arsenal completed an unbeaten tour of Asia with a 2-1 win against Japanese side Urawa Red Diamonds.
Arsenal had taken the lead through Lukas Podolski, a half-time replacement for Olivier Giroud, before Japan international Yuki Abe scored the equaliser with a long-range effort.
But Akpom sealed the victory for Arsenal eight minutes from time when he capitalised on a defensive blunder to score his fourth goal of a successful tour.
Arsenal could have won by more. Alex Oxlade-Chamberlain and Theo Walcott both hit the woodwork in the first half and Giroud saw a lofted shot drop just wide of the post.
But manager Arsene Wenger was happy to have come through a tough test after beating Nagoya 3-1 and putting seven goals past both the Indonesian Dream Team and Vietnam.
"We wanted a competitive game and we were not disappointed," Wenger told www.arsenal.com.
"The game was played at a good pace. They tried to catch us on the break, defended very well and were very sharp on counter attack so it was a good test for us."
