Korea’s biohealth startups are finding new ground in Japan’s rapidly expanding fertility and femtech market. At Ramen Tech 2025 in Fukuoka, reproductive health startup Greenish Inc. drew international attention with its inclusive fertility solutions Ferti-Max and Premia, signaling how Korean innovation is addressing Asia’s shared demographic challenges and redefining global reproductive care.
Greenish Showcases Fertility Innovation at Ramen Tech 2025 in Fukuoka
Greenish Inc., a Seoul-based reproductive health startup, participated in Ramen Tech 2025 in Fukuoka, Japan, where it presented its fertility solutions to investors, healthcare professionals, and potential partners through exhibition and IR sessions.
The company introduced two flagship products: Ferti-Max, a male fertility-enhancing functional lubricant, and Premia, a probiotic and folate supplement developed for women preparing for pregnancy. By addressing both male and female reproductive health, Greenish aims to close the gender gap that has long characterized infertility treatment.
The booth attracted strong attention for its focus on sperm activation as a fertility solution, a concept still relatively unfamiliar in Japan’s medical and consumer markets. The company also held multiple discussions with international institutions to explore future collaborations and market entry pathways.
Japan as a Strategic Market for Korea’s Biohealth Startups
Japan’s demographic landscape mirrors Korea’s in many respects — declining birth rates, delayed parenthood, and growing awareness of reproductive health. Yet, its market scale and regulatory openness to wellness technologies make it a critical target for Korean startups.
Greenish’s participation at Ramen Tech reflects how Korea’s biohealth and femtech startups are using Japan as a regional bridge for global expansion. The company’s approach aligns with national strategies to support K-startup globalization through biohealth exports, under initiatives backed by Korean innovation agencies such as KISED and KIC Tokyo.
Greenish on Building an Inclusive Future in Fertility Care
“Japan faces a similar demographic challenge as Korea, with low birth rates and rising infertility rates. However, its market size is even larger,” said Insung (Jade) Sung, CEO of Greenish. “We joined this global exhibition to explore the Japanese market and seek potential partners as part of our long-term global expansion strategy.”
Sung added that Greenish received enthusiastic responses from both Japanese visitors and professionals from other countries. “Each market has its own regulatory landscape, so we focused on sharing our achievements in Korea and outlining a realistic global roadmap.”
K-Startup Globalization Through Reproductive Health Innovation
Greenish’s traction in Japan illustrates how Korean startups in reproductive and women’s health are broadening Korea’s global innovation portfolio beyond cosmetics and digital healthcare. The company’s inclusive model, combining biotechnology, consumer health, and gender-balanced design, highlights new opportunities for cross-border collaboration in Asia’s femtech and biohealth sectors.
By targeting Japan first, Greenish is following a growing path of Korean startups leveraging cultural proximity, medical credibility, and regulatory familiarity to test and scale in mature Asian markets before entering North America and Europe. This approach also underscores how government-backed programs promoting Asia-focused expansion are helping startups in sensitive fields like fertility and health tech navigate cultural and ethical complexities.
Building Awareness and Market Readiness
Following the Fukuoka exhibition, Greenish plans to expand its market presence in Japan through SNS-based awareness campaigns, B2B partnerships with insurers, and a localization strategy tailored to Japanese consumers. These steps aim to position Greenish not only as a product innovator but also as a platform brand advancing inclusive reproductive care across Asia.
As fertility and population issues remain top priorities for both Seoul and Tokyo, startups like Greenish are showing how Korea’s startup ecosystem is evolving from technological excellence to societal impact, using innovation to address some of Asia’s most pressing demographic challenges.
