Global cutlery manufacturer Kai Corporation (Chiyoda-ku, Tokyo; President and COO: Hiroaki Endo) will once again collaborate with Ace Hotel Kyoto and Shinfoo-kan to support Earth Day initiatives, following last year's success.
Starting Friday, April 24, 2026, original design 'Paper Razors®'—developed with the environment in mind—will be distributed exclusively to guests staying at Ace Hotel Kyoto and visitors who complete a survey at the pop-up event in Shinfoo-kan.
This initiative celebrates Earth Day on April 22. The collaborative Paper Razor® will be available at Ace Hotel Kyoto and the 'Kai Prototype Exhibition' pop-up event at Shinfoo-kan.
The 'Kai Prototype Exhibition' at Shinfoo-kan will showcase carefully selected products from the 'Sharpness and Kindness Exhibition'—an event held annually since 2021 on 'Good Blade Day' (Nov 8)—that embody the Earth Day philosophy of consideration for the environment and society.
Additionally, the exhibition space draws inspiration from the design concept of 'Kai Hamono-ten,' Kai's directly managed street-front store set to open on May 1, 2026, in a renovated traditional Kyo-machiya. The space incorporates motifs such as traditional lattices and Noren curtains characteristic of Kyoto's townhouses.
Kai, a global manufacturer with a 118-year history, proposes its vision of 'sustainable design' for the next 100 years while cherishing the cityscapes and traditions of Kyoto.
