What EC Studio does

EC Studio is a Tokyo-based e-commerce operator founded in March 2014 that builds, markets, and sells proprietary direct-to-consumer beauty and health brands in Japan, led by Representative Director Shimada Reosuke. The company's product portfolio comprises four owned brands — WEEED (cosmetics), Finebase (health supplements), FINESPORTS (sports nutrition), and OptimalCi (beauty supplements) — distributed through dedicated brand EC sites and via the E!Choice multi-platform marketplace presence on Rakuten, Amazon, Yahoo Shopping, Qoo10, auPAY Market, and Mercari Shops. EC Studio also operates EC Medical, a physical pharmacy specializing in Kampo (traditional Chinese medicine) and pharmaceutical products, and runs a third-party EC consulting practice covering site production, promotion, and CRM support for other brands.

Revenue mechanics blend subscription/repeat-purchase D2C on owned brand sites, marketplace sales (transaction-fee based), EC consulting fees, and pharmacy retail. Group subsidiaries acquired in 2023 (Justy Corporation in July for hairbrush and TV-shopping distribution; ONEST Corporation in September for hydrogen-treatment equipment, salon channels, and overseas operations) broaden the platform into B2B salon distribution and select international markets. Capital structure shows registered capital of ¥70 million as of latest disclosure, against disclosed FY May 2023 revenue of ¥2,206,000,000 (approximately US$14–15 million), with 42 employees as of June 2024.

Since the July 2022 stock transfer to J Frontier Co., Ltd. (Tokyo Stock Exchange Growth: 2934), EC Studio operates as a subsidiary within a healthcare-cycle group that spans prevention, online consultation (SOKUYAKU), medication delivery, and now regulated pharmaceutical retail through EC Medical. Group-wide customer data sharing across 10 affiliated entities supports cross-sell and CRM, while certifications including Privacy Mark (2017) and ISO/IEC 27001 (2021) provide compliance credentials relevant to handling health and pharmaceutical consumer data.
