2007: six-year-old season
In March 2007, Daiwa Major was sent to the United Arab Emirates to represent Japan in the nine-furlong Dubai Duty Free at Nad Al Sheba Racecourse. He finished third of the sixteen runners behind Admire Moon and the South African challenger Linngari. The unplaced horses included English Channel, Miesque's Approval and Lava Man. On his return to Japan, Daiwa Major won the Yasuda Kinen at the third attempt, beating Kongo Rikishio by a neck, with the Hong Kong champion Good Ba Ba unplaced. Andō praised the horse's performance, pointing out that he had been unsuited by the moderate pace, whilst Uehara expressed his relief that the horse had shown no ill effects from his trip to Dubai. Three weeks later the horse was moved up in distance for the Takarazuka Kinen and finished unplaced behind Admire Moon.
Daiwa Major's autumn campaign began disappointingly in October when he was beaten as the odds-on favourite for the Mainichi Okan and then finished unplaced behind Meisho Samson in the Tennō Shō. In November he returned to form to take the Mile Championship for the second successive time, as he "dug in gamely" to win by a neck from the four-year-old Super Hornet. Daiwa Major ended his racing career in December when he again moved up in distance to contest his second Arima Kinen. He finished third behind American racehorse Matsurida Gogh, with second place being taken by his sister Daiwa Scarlet. The unplaced runners included Meisho Samson, Vodka, Pop Rock and Delta Blues.
At the end of the season, Daiwa Major won his second JRA Award for Best Sprinter or Miler, gaining 234 of the 289 available votes. He also finished third in the poll for the Best Older Male Horse. In the 2007 World Thoroughbred Racehorse Rankings, Daiwa Major was ranked the 29th best racehorse in the world.
