Thanko Co., Ltd. (headquartered in Chiyoda-ku, Tokyo; CEO: Taichi Arai) has launched the 'Hinayari Suiryu Kaimin Mat Lite' on June 17, 2026. The product will be available in limited quantities through Thanko's official online store and various e-commerce sites. Learn more This product is a water-cooling sleep mat that continuously circulates cold water within the mat to draw body heat away, providing sustained coolness even on sweltering nights. Place the water-flowing mat (700x1600mm) on a bed or futon, and connect it to the chiller unit (155×155×265mm) that circulates and cools the water. Fill the chiller unit with water and plug it in, and water will begin circulating through the mat. Unlike traditional cooling mats that tend to warm up from body heat, this product continuously cools the water using the unit's built-in fan, maintaining a refreshing cool sensation. Power consumption is only about 6W, making it highly energy-efficient. Even with the air conditioner set slightly higher, the mat cools the body directly, ensuring comfortable sleep even on tropical nights. Additionally, it features an off-timer function (1–12 hours) to prevent unnecessary power usage. Recommended for those who want to overcome uncomfortable nights, sleep soundly, and stay cool while saving energy. ● Achieving both cool comfort and unbeatable value with 'simple operation'—no remote control This product is part of the 'Warehouse Revival Project,' which revives unopened inventory from the popular water-flow mat series, available exclusively through official online channels. Responding to rising electricity costs and growing demand for energy-saving solutions, the company intentionally removed the remote control and optimized the design for intuitive 'button-only operation' on the main unit, making the water-cooling experience accessible to more people. Furthermore, by adopting a focused '6-month warranty' to support just one summer season, the company has eliminated all unnecessary costs. By streamlining the design to its essentials, the product achieves an outstanding cost-performance ratio, priced at ¥12,800 (tax included)—one of the best in the series. It is being released as a practical, budget-friendly model to comfortably support households during hot summer nights without straining household budgets. ■ Cooling mat with continuous water flow ■ Water circulates through the mat when water is added to the chiller and powered on ■ Water in the mat is cooled by the chiller’s filter and fan ■ 3-level airflow adjustment ■ Off-timer up to 12 hours ■ Can also be used as a personal cooling fan ■ USB-powered for use during car camping or outdoor camping ■ Energy-efficient at only 6W, allowing worry-free use ・Dimensions / Unit: 155W × 155D × 265H (mm), 　　　　　Mat: 700W × 1600L (mm), Water circulation hose: 1.2m ・Weight / Unit: approx. 1.0kg, Mat: approx. 900g ・Power supply / USB 5V 1.2A or higher ・Power consumption / USB: 6W ・Modes / 3 levels (High, Medium, Low) ・Timer settings / 1–12 hours ・Usable water temperature / Up to 40°C ・Cable length / Approx. 1m ・Water tank capacity / Approx. 1.7L ・Materials / Unit: ABS, Mat: PVC ・Set contents / Main unit, mat, water circulation tube, USB cable, water circulation filter, 　　　　　　　Cooling fan attachment, water drainage pump, Japanese instruction manual ・Warranty period / 6 months from date of purchase ・Release date / 2026/06/17 ・Model/JAN / WATL26SWH / 4580060606405 Hinayari Suiryu Kaimin Mat Lite [Selling Price] ¥12,800 (tax included) https://www.thanko.jp/view/item/000000004841 Hinayari Suiryu Kaimin Mat Sleep mat with continuous internal water flow for all-night cool comfort ¥19,800 https://www.thanko.jp/view/item/000000004842 ■ Product inquiries Thanko Co., Ltd.
