Ishibashi was again in the saddle when the filly started favourite for a maiden race for over the same distance at Tokyo Racecourse on 9 October and recorded her first success as she produced a strong late run down centre of the straight to take the lead inside the last 200 metres and win by two lengths from the colt Yuino Gotoku.

Stars On Earth ended her first campaign in the Akamatsu Sho, a minor event over 1600 metres at Tokyo on 21 November when she started favourite but came home third of the nine runners behind Namur and Personal High.

[7] On her first appearance as a three-year-old Stars On Earth started the 3.3/1 favourite when she was stepped up in class to contest the grade 3 Fairy Stakes over 1600 metres at Nakayama Racecourse on 10 January but despite producing a strong late run along the inside rail she was beaten a neck into second place by Lilac.

[8] In the Grade 3 Daily Hai Queen Cup at over the same distance Tokyo a month later she was again the beaten favourite, going down by a neck to Presage Lift after briefly taking the lead in the last 200 metres.

She looked unlikely to obtain a clear run but found a gap in the closing stages and produced an impressive burst of acceleration to catch Water Navillera on the line and win by a nose.

[20][21] After recovering from the conditions of the previous year, it was announced that the horse would be entered to the Osaka Hai to start off the season,[22] but at the race Stars of Earth was beaten by a nose by Jack d'Or.

[26] Upon returning, it was announced by Shadai Racehorsing that the horse will be entered to the autumn edition of the Tenno Sho, with Mirco Demuro as her new jockey as Lemaire is scheduled to ride Equinox for that race.
