Taiko Pharmaceutical to Launch First Official Apparel T-Shirts Inspired by Seirogan

Taiko Pharmaceutical Co., Ltd. announced that it will begin selling original apparel T-shirts inspired by its flagship product, Seirogan with the trumpet logo, from Wednesday, May 20, 2026, through its official online shop TAIKODIRECT, Rakuten Ichiba, and Amazon. This marks the company’s first official sale of self-planned original apparel items. The Seirogan series has supported household health for more than 120 years as a familiar family medicine. In recent years, Taiko Pharmaceutical has worked to make the brand feel closer to consumers, launching original goods such as plush toys and keychains in 2025. Designs featuring a surreal and charming stomach motif, along with a “retro yet new” reinterpretation of the traditional packaging, drew strong attention on social media. Product announcement posts on the official Seirogan brand X account recorded approximately 895,000 impressions in total and were well received by customers across generations. As a new initiative to deepen consumer touchpoints with the brand, the company will now launch official apparel items. The first lineup consists of three original T-shirt designs intended to let consumers express familiarity and affection for the brand through everyday fashion. The company plans to expand the product lineup in the future while incorporating customer feedback, continuing to create new brand experiences for Seirogan that can be loved across generations. The T-shirts come in three designs, each based on iconic Seirogan elements. They use fabric with moderate thickness that resists stretching and transparency, while the neckline features durable double stitching to balance everyday durability with comfortable wear. Sizes are available in S, M, L, and XL, and the items are designed as unisex apparel. The three products are the “Seirogan Bottle T-shirt,” featuring a simple and playful Seirogan bottle design on the chest; the “Seirogan Trumpet Logo T-shirt,” a back-print design with a modernized version of the trademark trumpet logo and graphical “seirogan” lettering; and the “Seirogan-kun, Seirogan Sugar-Coated A-chan T-shirt,” featuring a friendly illustration of Seirogan-kun and Seirogan Sugar-Coated A-chan peeking out from a chest pocket. Each T-shirt is priced at 3,850 yen including tax and is available in white, black, and gray. The white and black versions are made of 100% cotton, while the gray version is made of 98% cotton and 2% polyester. Sales channels include Taiko Pharmaceutical’s official online shop TAIKODIRECT, its Rakuten Ichiba store, and Amazon. Taiko Pharmaceutical stated that it will continue leveraging its brand value as a household medicine manufacturer close to daily family life, while promoting new initiatives that contribute to people’s physical and mental health and to richer everyday living.
