K-pop’s dominance in Japan just got another stamp of approval. The Recording Industry Association of Japan (RIAJ) has dropped its latest round of official certifications, and the list reads like a who’s who of the genre’s biggest current acts — from NCT WISH’s standout double platinum win to a wave of platinum and gold honors across nearly a dozen groups.

How RIAJ Certifications Actually Work?
Before diving into the winners, it helps to understand the scale. The RIAJ certifies albums based on units shipped in Japan: gold kicks in at 100,000 units, platinum at 250,000, and million status requires a full 1,000,000 units shipped. These certifications are a serious benchmark in one of the world’s largest music markets, making this month’s haul especially significant.
K-Pop September 2026 RIAJ Certifications

| Double Platinum | NCT WISH | “YO-I-DON! / BOY MEETS GIRL” |
| Platinum | TXT | “Setsuna Hanabi” |

The Standout: NCT WISH’s Double Platinum Milestone
NCT WISH leads the pack this month, with their Japanese single album YO-I-DON! / BOY MEETS GIRL crossing the 500,000-unit mark to earn double platinum status — a significant achievement that cements the group’s rapidly growing presence in the Japanese market.
A Strong Platinum Wave Across the Board
Right behind them, five separate releases each crossed the 250,000-unit platinum threshold. TXT’s Setsuna Hanabi and RIIZE’s Sunburst mark continued momentum for two of K-pop’s most consistent Japan performers, while ENHYPEN’s Korean mini album THE SIN : BLISS shows that even non-Japanese releases can achieve platinum status through Japan’s import and streaming sales. TWS’s SODA SODA and NiziU’s GOOD GIRL BUT NOT FOR YOU round out the platinum tier, reflecting broad-based strength across both newer and more established acts.
Gold Certifications Round Out the List
ZEROBASEONE’s KAIKILOVE, LE SSERAFIM’s PUREFLOW pt. 1, and ALPHA DRIVE ONE’s UNBREAKABLE : 少年BEAST all secured gold certification for surpassing 100,000 units. Notably, LE SSERAFIM’s certification — like ENHYPEN’s — comes from a Korean-language album, underscoring how strongly Korean releases now perform in the Japanese market without needing a Japan-specific version.
Why This Matters?
Japan remains one of the most lucrative physical and digital music markets globally, and consistent RIAJ certifications across multiple K-pop generations — from veteran groups to recent debuts — reflect the broader staying power of the Korean Wave (Hallyu) as a cultural and commercial force well beyond Korea’s borders.
