started at odds of 13.5/1 for the 78th edition of the Satsuki Sho over 2000 metres. Wagnerian started favourite ahead of Stelvio with the other thirteen runners including Kitano Commandeur (Sumire Stakes), Time Flyer (Hopeful Stakes, Gendarme (Daily Hai Nisai Stakes), Oken Moon (Tokinominoru Kinen) and Generale Uno (Keisei Stakes). Aithon set a strong pace from Jun Valerot and Generale Uno with the trio pulling many lengths clear of the others who were headed by Epoca d'Oro. The leaders began to tire approaching the final turn and Epoca d'Oro gained the advantage from Generale Uno in the last 200 metres before drawing away to win by two lengths from Sans Rival. Tosaki commented "I was able to position him as planned. He ran in good rhythm and responded well rounding the final corner. He's a smart horse and is developing with each race. His powerful run today shows that he will have no problem handling the extra distance in the Tokyo Yushun". At Tokyo Racecourse on 27 May Epoca d'Oro was made the 8.5/1 fourth choice behind Danon Premium, Blast Onepiece and Kitano Commandeur in the 85th running of the Tokyo Yushun over 2400 metres. He took the lead soon after the start, led the field into the straight and repelled several challengers before being caught in the final strides by Wagnerian and beaten half a length into second place. After a break of almost four months the colt returned for the Kobe Shimbun Hai at Hanshin Racecourse in September and started joint-favourite with Wagnerian. After stumbling as he exited the starting gate he raced towards the rear of the field before staying on in the straight and came home fourth of the ten runners. On his final start of the season Epoca d'Oro started third favourite for the Kikuka Sho over 3000 metres. He was in contention for most of the way but faded in the closing stages to finish eighth behind Fierement, beaten five lengths by the winner. In the 2018 World's Best Racehorse Rankings Epoca d'Oro was rated the 15th best three-year-old colt in the world and the 78th best horse of any age or sex. In January 2019 Epoca d'Oro finished fourth behind Blast Onepiece, Wagnerian and the dirt champion Le Vent Se Leve in the poll to determine the JRA Award for Best Three-Year-Old Colt for 2018 . 2019: four-year-old season Epoca d'Oro began his
