The Five O'clock Club

What The Five O'clock Club does

The company operates as LeoClie Co., Ltd. (株式会社LeoClie), a privately held Japanese corporation headquartered at 150-0013 Shibuya-ku, Tokyo, with 9 million JPY in registered capital and led by representative director Bridge Hashimoto (橋元昇太). Its principal business is the development, manufacture, and sale of male enhancement dietary supplements under the Volstar brand, with the flagship product being Volstar Beyond BLAST (糖素減/とうそげん), a 120-capsule, 1-month supply daily supplement combining L-citrulline (1,043mg), L-arginine (421mg), zinc (12mg), and 236 distinct ingredients (40 vitamin/mineral compounds, 39 animal-derived compounds, and 157 plant-derived compounds), formulated with four proprietary patented absorption-enhancing ingredients (ジオパワー15, バイオペリン, アミノシール, アストラジン). The product is manufactured at a GMP-certified domestic Japanese facility with radioactive substance testing, and is targeted at men experiencing confidence and sexual-performance concerns related to penis size, erectile function, stamina, and age-related vitality decline. The product portfolio has expanded to include Volstar Liquid (a topical companion cream that won the 2019 Monde Selection Gold Award) and Volstar Fragrance (a pheromone cologne), and the brand crossed into the female segment in December 2019 with Laulala, an intimate body lotion distributed via ShareLove on the FRIL marketplace.

The go-to-market model is direct-to-consumer e-commerce, with the official website (svolstarofficial / svolstarshop) positioned as the primary and recommended channel — supported by a permanent full-refund guarantee and subscription (定期便) pricing — complemented by authorized storefronts on Amazon Japan (L-Citrulline Store), Rakuten, and Yahoo Shopping/PayPay Mall. Pricing is multi-tier: single-box at a promotional ~12,800 JPY (vs. 18,400 JPY standard), subscription with a 5% ongoing discount and multi-delivery lock-in, and aggressive multi-box bulk campaigns offering up to 68% off and bundled bonus products. Customer acquisition is overwhelmingly digital: 45,000+ user reviews and testimonials, third-party Japanese review and comparison blogs, YouTube influencer content (e.g., タッちゃんネル中年男性タ, 精力剤のイロハ), earned media coverage in TV/print magazines, and organic social discussion on Twitter, Yahoo Chiebukuro, and 5channel. The brand has accumulated 800,000+ cumulative boxes sold, 15 consecutive months of No.1 domestic Japanese online sales ranking (Jan 2019 – Mar 2020), 7 category championships, and 17 industry accolades, and receives a >99.8% customer satisfaction rate (return rate <0.2%).

Note: firmographic metadata lists the entity as 'The Five O'clock Club' in Sarasota, Florida with 8 employees, which is inconsistent with the substantive operating data, which is centered on Tokyo-based LeoClie and its Volstar consumer supplement business; analysis has been grounded in the operating-company evidence.
