After a break of more than four months, the colt returned for the Listed Hagi Stakes over 1800 metres at Kyoto Racecourse on 27 October and won again, beating Jamil Fuerte and six others.

Ridden by Mirco Demuro, he was made the 0.8/1 favourite ahead of twelve opponents including the Tokyo Sports Hai Nisai Stakes winner Nishino Daisy.

In the run-up to the race his assistant trainer Yasuyuki Tsujino said "Things have been fine with him, his breathing's good, and he's run well in training with control and power...

"[10] Ridden for the first time by Christophe Lemaire he was made the 0.7/1 favourite ahead of Admire Mars in an eighteen-runner field which included Velox, Danon Kingly, Fantasist (Keio Hai Nisai Stakes) and Meisho Tengen (Yayoi Sho).

After racing in mid-division in the early stages, Saturnalia moved forward on the final turn and made a strong challenge in the straight taking the lead from Velox 200 metres from the finish.

After racing in eleventh place for most of the way he made rapid progress in the straight but never looked likely to catch the leaders and came home fourth behind Roger Barows, Danon Kingly and Velox, beaten three and a quarter lengths by the winner.

After an absence of almost four months Saturnalia returned in the Kobe Shinbun Hai over 2400 metres at Hanshin on 22 September and started the odds-on favourite in an eight-runner field.

[12] On 27 October Saturnalia faced older for the first time in the autumn edition of the Tenno Sho over 2000 metres at Tokyo and started the 2.4/1 second favourite in a sixteen-runner field.

[14] On his first run as a four-year-old, Saturnalia started the odds-on favourite for the Grade 2 Kinko Sho over 2000 metres at Chukyo Racecourse on 15 March when his ten rivals included Lord My Way (Challenge Cup), Last Draft (Keisei Stakes) and Nishino Daisy.

He raced towards the rear along the inside rail before being switched to the outside in the straight but despite making steady progress he was unable to threaten the leaders and came home fourth behind Chrono Genesis, Kiseki and Mozu Bello.
