What Eureka Inc. does

Eureka Inc. (株式会社ユリイカ) is a Tokyo-based PR and casting agency founded in September 2016, operating from Hanegi Studio in Setagaya-ku. The firm delivers six integrated service lines — talent casting, event management, Buzz PR (influencer marketing), media and PR relations, creative production, and global project support — marketed as a "360-degree caring" PR & Casting offering. Its client base is concentrated in luxury and premium fashion, beauty, hospitality, sports, and selective tech/urban development segments, with named engagements for Tommy Hilfiger, Saint Laurent, Parfums Givenchy, LeSportsac, Conrad Tokyo, New Balance Golf, docomo 5G, and the Mary Quant exhibition, among others.

The company operates without proprietary technology platforms; its core capability is its curated network of influencers, models, media contacts, and a multilingual leadership team (Japanese, Korean, and seven-language fluency among COOs) that enables cross-border project execution. Creative production (video, music, design) is delivered through a sister-company ecosystem anchored by M2 Creative Group and affiliates Obscure Collective, Latina International, Arriba Entertainment, and AQUARIUM, allowing end-to-end delivery under a single point of contact.

Commercially, Eureka is a privately held, founder-led firm with 6 employees, 5,000,000 yen of registered capital, no disclosed external funding, and no public revenue data. Its go-to-market is direct enterprise field sales to brand clients and agencies, with project-based, non-publicly-disclosed pricing. The firm reports geographic reach into East Asia and Europe through cross-border event work, though its primary delivery base remains Tokyo.
