Kagi110-Key Ambulancy Association

Kagi110-Key Ambulancy Association (in Japanese, 一般社団法人カギの110番・カギの救急車) is a Japanese general incorporated association that operates as the umbrella body for a nationwide network of locksmith shops trading under the shared trademarks "Kagi no 110-ban" (Key 110 / the key emergency number) and "Kagi no Kyukyusha" (Key Ambulance). According to its own corporate greeting, it describes itself as Japan's only corporate association of locksmiths, formed by shops across the country that established themselves under the same trademark. Its stated purpose is to raise technical skill, knowledge and ethics across member stores and to share information so that customers receive a uniform national standard of service, working together with lock manufacturers and related companies. The group's core business is locksmith and crime-prevention services: opening locked doors (kaijō), lock replacement and installation, duplicate key cutting, door and door-closer repair, safe opening and related security products. The official site organizes these into categories such as key trouble, key replacement/installation, duplicate key service, door surroundings, and crime-prevention measures, and it markets an emergency call-out model — the "key ambulance" idea — alongside a store-locator that lets customers find the nearest member shop. Member shops are individually operated but share the brand, and the association publishes a recruitment list of member stores hiring staff, with locations ranging from Sendai and Utsunomiya to Chiba, Kawasaki, Kamata, Matsumoto and Nagoya. The association is headquartered in Minato, Tokyo, and its representative director is Osamu Asayama (浅山 修). It is a private general incorporated association rather than a listed company. A related operating company, Jake Corporation (株式会社ジェイクライプ), also based in Minato, Tokyo, has acted alongside the association in trademark enforcement. The group presents itself as a pioneer of the crime-prevention industry in Japan and aims for its brand names to become synonymous with safety and security. A significant part of the association's public activity concerns protecting its trademarks. Its website carries a dedicated section on measures against trademark infringement, warning customers about malicious operators and imitation trademarks that mimic the "Kagi no Kyukyusha" name, and it has pursued litigation against other locksmith businesses over the use of similar marks in website metadata. The site also documents community activities, media appearances by member stores, and promotional tie-up campaigns with Japanese film releases.

The Kagi no 110-ban / Kagi no Kyukyusha group presents itself as a pioneer of Japan's crime-prevention industry. Its corporate greeting states that the general incorporated association was established by locksmith shops across the country that set up under the same trademark, making it, in its own words, Japan's only corporate association of locksmiths. The association's purpose is to improve the technical skill, knowledge and ethics of member shops and to share information so that a uniform national service standard can be offered, cooperating with lock manufacturers and related companies and making the most of the nationwide store network. The association is headquartered in Minato, Tokyo, and its representative director is Osamu Asayama. A closely related company, Jake Corporation (株式会社ジェイクライプ), also headquartered in Minato, Tokyo, has acted together with the association in legal matters. The group operates through independently run member stores that share the brand, and the association's website provides a nationwide store locator as well as a list of member stores that are recruiting staff, with examples including stores in Sendai (Kotodai and Rokuchonome), Utsunomiya, Central Chiba, Kawasaki, Kamata, Matsumoto and Kurokawa in Nagoya. A defining theme of the association's public history is the protection of its trademarks. Its website devotes a section to measures against trademark infringement, and it has published notices on the conclusion of trademark infringement injunction and damages lawsuits. In one notice dated September 2015, the association and Jake Corporation stated that they had filed a lawsuit at the Tokyo District Court on May 27, 2015 against Ritz Co., Ltd. (headquartered in Nagoya, Aichi), seeking an injunction against trademark infringement and damages, and that the case had ended in a settlement under which Ritz paid a settlement fee for trademark infringement. Earlier notices dated September 2013 and October 2013 described similar lawsuits filed on January 9, 2013 at the Tokyo District Court against R Security Co., Ltd. (Shinagawa, Tokyo) and ARS Co., Ltd. (Chiyoda, Tokyo), both of which also ended in settlements in which the defendants paid settlement fees. The claims in these cases concerned, among other things, the use of the group's marks in title tags or meta tags of website HTML files advertising locksmith goods and services. Beyond litigation, the association warns customers on its website about malicious operators and fake advertisements that impersonate "Kagi no Kyukyusha," and it maintains a trademark list and press releases. It also documents community and social contribution activities, such as participation in the Shiba district clean-up campaign around Toranomon and Kamiyacho, and media cooperation, such as the Shinjuku store assisting a Fuji TV news program. The group has run promotional tie-up campaigns with Japanese film releases, and in 2026 it announced a business alliance with JA Amenity House Co., Ltd. covering key and crime-prevention services, as well as an exhibition for member stores.
