Musinsa Standard sees sevenfold growth in Japan
On September 2, Musinsa announced that its private brand, Musinsa Standard, achieved seven times the transaction volume in Japan during the first half of 2026 compared to the same period last year. This growth was significantly fueled by the "Musinsa Station in Harajuku" pop-up store held in August, which saw over 40% of Japanese first-time buyers on the global platform originating from the event. The success has solidified Musinsa Standard’s role as a gateway brand for K-fashion among Japanese consumers, directly boosting sales for other K-brands featured in the pop-up.
Harajuku pop-up triples K-brand transactions
The "Musinsa Station in Harajuku" pop-up, which ran throughout August, resulted in a threefold increase in transaction values for the 73 participating K-fashion brands. Local media reported that the event attracted significant foot traffic from Japanese Gen Z consumers, validating Musinsa’s strategy of using physical pop-ups to drive online global store traffic. The high engagement rates have accelerated plans for permanent offline stores in Tokyo and other major Asian cities.
Seoul Fashion Week expands to Lotte World Tower
The 2027 Spring/Summer Seoul Fashion Week kicked off on September 1, marking a significant structural change by splitting events between Dongdaemun Design Plaza (DDP) and Lotte World Tower. This six-day event features runway shows from 31 brands and a trade show with over 100 labels, aiming to integrate fashion with broader K-culture experiences. The expansion to the iconic Lotte World Tower is intended to attract international buyers and tourists by leveraging the landmark’s visibility.
Musinsa posts record H1 revenue despite profit dip
Musinsa reported record first-half consolidated sales of 821.7 billion won ($598.4 million), a 22% increase year-over-year. However, operating profit declined by 11.2% due to increased costs associated with aggressive global expansion and offline store openings. The company’s overseas export sales grew ninefold, highlighting the shift from a domestic online marketplace to a global omnichannel retailer.
Local view
Local Korean business media are closely monitoring Musinsa’s "profitability vs. growth" trade-off. Seoul Economic Daily highlights that while revenue hit an all-time high, the drop in operating profit reflects the heavy investment phase required to secure overseas market share, particularly in Japan where sales jumped sevenfold. Hankyung reports on the cultural impact of the Harajuku pop-up, noting that it effectively replicated the "Seongsu-dong" vibe in Tokyo, drawing massive crowds of Japanese teenagers (10-20s age group) and proving that K-fashion’s aesthetic appeal translates well into physical retail experiences in Japan.
