KAI Japan Celebrates 'Good Blade Day'

On November 7, 2025, KAI Group, a renowned global knife manufacturer, organized a special PR event at the Kanze Noh Theatre in Ginza, Tokyo, in anticipation of 'Good Blade Day,' celebrated on November 8. The event featured the esteemed actress Koyuki as a special guest, creating an atmosphere filled with anticipation and excitement.

As a firm that has been committed to exemplifying quality and craftsmanship for 117 years, KAI's dedication to innovation while honoring tradition resonates deeply within the culinary and crafting communities. This year's event marked the eighth iteration of their celebration, showcasing their ongoing partnership with Kanze Noh Theatre, which has a 700-year history of preserving the culture of Noh theater while embracing modern challenges.

During the event, KAI CEO Hiroaki Endo unveiled the company’s latest initiatives, including a new philosophy diagram and an introduction to the 'Wild Blacksmith Succession Project'. This project aims to preserve and pass on the traditional blacksmithing techniques that the city of Seki, renowned for its knife-making, is known for. Endo also discussed the current state of inbound tourism to Japan, expressing hope to attract more international customers through their high-quality products.

New Product Launches

The spotlight of the event was undoubtedly the unveiling of two groundbreaking razor products that are set to hit the market in 2026: the 'Nade-sori' and 'THOLL'.

The 'Nade-sori', described as the world's first razor designed for a gentle, playful shave, incorporates two innovative resin guards that prevent the blade from direct contact with the skin, reducing the risk of cuts significantly. This design was inspired by rising trends in shaving among younger demographics, acknowledging the need for a safe and effective shaving solution for all ages. Unlike traditional razors, it allows users to shave without the need for shaving cream or lather, enhancing convenience for quick touch-ups anywhere.

On the other hand, 'THOLL' is a revolutionary full-metal razor featuring a replaceable blade system without any plastic components. It is designed to marry sustainability with functionality, making it an economical choice for environmentally conscious consumers. KAI will begin a limited test sale through Kickstarter in March 2026, carefully gauging customer demand before further distribution.

A Glimpse into Koyuki’s Culinary Preferences

The event’s ambiance was further enriched by a talk session where actress Koyuki, who has been a long-time user of KAI products, shared her insights and experiences related to culinary tools. With a graceful presence in traditional attire, she expressed gratitude for being part of this significant milestone for KAI.

Koyuki spoke candidly about her daily culinary practices, emphasizing how integral KAI's tools are in her kitchen. She recounted a particular experience involving the 'Nade-sori', noting how her son, who was initially apprehensive about hair removal, embraced the ease of use that the new product offers. She reaffirmed the ease and comfort the design provides, making it suitable even for teenagers who typically shy away from such personal grooming discussions.

In a light-hearted twist, she presented her favorite KAI tools, including a kitchen scissors and a Damascus knife, sharing how they have become staples in her home cooking adventures.

An Immersive Display

Complementing the event was a concept design exhibition titled 'Sharpness and Gentleness', featuring design ideas from KAI's team and students from art universities. This exhibition aims to bridge the artistic expression of knives and their practicality, inviting attendees to explore creativity in kitchen and craft tools.

The exhibition will run from November 7 to November 10 at Shibuya Sakura Stage, highlighting the multifaceted use of blades in daily life.

As the event concluded, Koyuki and Endo shared their hopes for the future generations to carry on the spirit of craftsmanship that KAI embodies. They encouraged attendees to appreciate not just the products, but the artistry and tradition that come with each blade.

This year's 'Good Blade Day' PR event successfully showcased KAI's innovative spirit and commitment to craftsmanship while connecting with the audience through an engaging celebration of culture and technology.
