'Breathable Domestic Tatami Pillow' Launches Pre-orders on Creema SPRINGS to Enhance Summer Sleep

Ikehiko Corporation, a 138-year-old traditional Igusa (rush grass) product manufacturer (HQ: Ooki, Fukuoka; CEO: Kosei Inokuchi), will begin domestic pre-orders for its natural Igusa 'Tatami Pillow' via the handmade craft crowdfunding service 'Creema SPRINGS' starting at 10:00 AM on May 23, 2026 (Sat). The pillow leverages the unique moisture-wicking, antibacterial, deodorizing properties and natural forest-like scent of Igusa to offer a new sleep accessory designed for Japan's hot and humid summer environment.

This product previously garnered significant attention in the overseas crowdfunding platform 'Kickstarter,' raising over 8 million yen. Given the positive response, the company is now introducing this 'Igusa comfort' to the Japanese market via Creema SPRINGS. The project runs until June 30 (Tue).

### Development Background

#### Wisdom of 'Tatami' for Hot Japanese Nights

Recently, concerns about summer sleep environments have been increasing, with issues like coldness from air conditioning, humidity from night sweat, and odors in bedding. We considered how to leverage the power of 'Tatami,' which has been a staple in Japanese life for centuries. We developed the 'Tatami Pillow' to offer a natural, comfortable sleep environment through the moisture-wicking and aromatic properties of natural Igusa. The head area is prone to sweating and heat accumulation. Igusa excels in moisture regulation, keeping a crisp feel while reducing stuffiness. Furthermore, it is known for deodorizing capabilities against ammonia and antibacterial properties, serving as a reliable natural material in Japanese housing for generations.

#### The Global Appeal of 'Sleeping on Tatami'

This product was previously featured on the overseas crowdfunding platform 'Kickstarter,' achieving over 8 million yen in total funding. Global users responded positively, appreciating the comfort of natural materials and the unique experience of Japanese culture. Interest in Japanese material culture remains high, with users enjoying the healing scent of Tatami and the calmness offered by natural materials, spreading empathy for the new experiential value of 'sleeping on Tatami.'
