Introducing the Revolutionary SAKASANANO Umbrella

Waterfront, a distinguished umbrella brand celebrating its 40th anniversary this year, is launching the SAKASANANO umbrella on June 17, 2026, at 5 PM, both at their Waterfront JIYUGAOKA store in Tokyo and through their official online shop. This umbrella incorporates Toray's NANODESIGN® technology, setting a new standard in water resistance.

The Challenge of Modern Weather Conditions

Recent changes in Japan's rainfall patterns present a unique challenge for traditional umbrellas. While the number of rainy days has been steadily decreasing, the intensity of rainfall is increasing, resulting in severe short-term downpours. This phenomenon - characterized by fewer rainy days but heavier rain - necessitates higher-quality umbrellas that can reliably withstand challenging weather conditions. Moreover, growing environmental awareness urges the need for umbrellas without harmful chemical treatments traditionally used for water repellency.

Innovative Technology Behind SAKASANANO

The SAKASANANO umbrella uses Toray's patented NANODESIGN technology, which allows for precise control of fiber thickness and cross-section at the nano level. By shaping the fiber surface to create micro-embossed patterns, the umbrella achieves superior water-repellency, eliminating the need for eco-harmful water-repellent agents.

1. Sustainable Water Resistance: With NANODESIGN, SAKASANANO maintains exceptional water resistance without relying on hazardous chemicals, ensuring both environmental safety and outstanding performance.

2. Reverse Structure for Convenience: Featuring a reverse-opening design, SAKASANANO minimizes contact with wet surfaces, keeping hands and clothing dry when the umbrella is closed. This innovative structure ensures that the wet side of the umbrella remains contained, making it perfect for entering and exiting vehicles or public transport.

3. Durable and Repairable Design: Access to sustainable design is enhanced by enabling users to replace the fabric of the umbrella instead of discarding the entire frame. This initiative addresses waste issues, as every year approximately 80 million umbrellas are thrown away in Japan, with many ending up in landfills without being recycled.

4. Streamlined Aesthetics: Designed by Yota Tsukuda, SAKASANANO's design eliminates excess to create a functional yet elegant accessory. It offers a balanced aesthetic suitable for all genders, showcasing a seamless integration of form and function.

Temporary Display in Daikanyama

To celebrate the launch, a limited-time display will be available at Daikanyama T-Site and Tsutaya Electronics+, where customers can experience the superior water resistance of SAKASANANO firsthand. Sales will commence at the Daikanyama T-Site on June 17, 2026, allowing interested fans to purchase their own.

SAKASANANO, priced at 14,300 yen (including tax), promises to redefine our expectations of rain umbrellas, merging technology with sustainable practices. Join Waterfront in making this transition towards environmentally friendly products that not only cater to our daily challenges but also reflect our responsibilities towards the environment.
