Having been defeated by Mark Crear in Munich at the weekend, Jackson was credited with a sluggish 13.55sec to Wade's 13.50. Britain's world champion was slow out of the blocks and never got into his stride.
"I'm not that disappointed with the result," Jackson said. "It still felt good to get out there and run."
The world 100m record holder, Maurice Greene, also struggled on the Tokyo track. Although he beat his fellow American Curtis Johnson comfortably, his time of 10.35sec confirmed that the world champion has gradually wound down his season since winning his gold medal in Seville. Johnson finished second in 10.40 and China's Yin Hanzhao third in 10.56.
In the meeting's most exciting race, the men's 400m, the American Antonio Pettigrew, the 1991 world champion, came off the final bend almost eight meters down on Alejandro Cardenas but caught the Mexican just before the finish. Pettigrew clocked 46.08, with Cardenas second in 46.13.
In the All Africa Games in Johannesburg, Ghana's Leo Myles Mills beat Frank Fredericks, of Namibia, in the 100m. Mills got out of the blocks quickest and clocked to his second sub-10-second time, winning in 9.99. Second was Nigeria's Francis Obikwelu in 10.01, with Fredericks third in 10.10.
"The fitness was just not there after my injury," said Fredericks, who was forced him to pull out of the World Championship finals in Seville because of a sciatic problem. "I'm not taking anything away from Leo, because he deserved to win. I'm just glad to be taking a medal home."
