Miku Matsushima and Lee Seung Soo Win Singapore Youth Smash U15 Titles

Japan’s 12-year-old Miku Matsushima and Korea’s Lee Seung Soo emerged as the U15 girls' and boys' singles champions at Singapore Youth Smash 2026, held at The Kallang in Singapore from February 26 to March 1. An Instagram announcement presented both winners and included the line "Presenting your Singapore Youth Smash 2026 U15 Boys' and Girls' Singles Champions - Miku Matsushima and Lee Seung Soo! ... claim a 3-2 win!⚡️"; the 3-2 scoreline is included in the social post but the caption does not specify which final the result refers to.

The Youth event ran alongside the fifth edition of Singapore Smash 2026 Presented By Resorts World Sentosa, with the broader tournament weekend carrying a total prize purse of US$1.55 million. Organizers billed the youth competition as a showcase for the next generation, inviting comparisons to the tournament tagline that the Youth event offers a preview of future champions as they begin their journey "from Day 1 to World No. 1."

Matsushima arrived in Singapore already one of the most-decorated players in junior circuits. "12-year-old Miku Matsushima is set to continue the proud family tradition and emulate the footsteps of older brother Sora Matsushima," the tournament preview noted, and detailed that Sora, 18, "has developed into one of table tennis’ biggest names, winning numerous titles during his time on the WTT Youth Series, and clinching a WTT Champions title on his way to World No.8." The preview also recorded Miku’s youth-series haul: "She already holds 13 WTT Youth Series titles to her name across all age disciplines, with four of those coming at U19 Girls’ Singles level."

Lee Seung Soo, also referenced in some pre-event material as Lee Seungsoo, extended an established run at the U15 level. Pre-tournament coverage described him as "the reigning U15 champion in Singapore and Sweden" and said he entered the weekend aiming to "dominate his age group again while pursuing redemption in the U19 event." The boys' draw had been expected to be competitive, with challengers including Kuo Guan-Hong of Chinese Taipei, identified as the reigning U19 champion, and Alan Kurmangaliyev of Kazakhstan, noted as a recent Youth Smash semifinalist.

In the U15 girls' field, Zhu Qihui of China had been highlighted as a contender pursuing a fourth consecutive Youth Smash title, aiming to "extend her perfect streak." Final opponents for Matsushima and Lee, set scores beyond the Instagram 3-2 line, and post-match comments from the champions were not included in the available announcements.

Matsushima’s U15 title adds to a rapid junior résumé that already includes double-digit WTT Youth Series trophies, while Lee’s win continues a run that placed him among the most consistent performers at U15 across recent Youth Smash stops. Their victories underline the tournament’s role as a stepping stone toward the senior circuit, and they leave Singapore with U15 crowns as the wider Singapore Smash weekend moves toward its conclusion.
