[6] On his three-year-old debut, sixteen days after his final run of 2016, Al Ain was moved up in class to contest the Grade 3 Shinzan Kinen at Kyoto on 8 January and sustained his first defeat as he came home sixth of the fifteen runners behind Kyohei, Taisei Starry, Persian Knight, Trust and My Style.

After a break of two and a half months the colt returned for the Grade 3 Mainichi Hai (a trial race for the Satsuki Sho) over 1800 metres at Hanshin in which he was ridden by Kohei Matsuyama and started the 6.7/1 second favourite behind Satono Arthur in an eight-runner field.

The filly Fan Dii Naa (winner of the Flower Cup) started favourite while the other contenders included Suave Richard (Tokinominoru Kinen), Cadenas (Yayoi Sho), Persian Knight, Rey de Oro, Win Bright and Satono Ares (Asahi Hai Futurity Stakes).

After being slightly hampered early in the straight he stayed on well on the outside without ever looking likely to win and came home fifth behind Rey de Oro, Suave Richard, Admirable and My Style, beaten just over two lengths by the winner.
