Casio Computer Co., Ltd. is a Japanese electronics company best known internationally for watches, calculators and electronic musical instruments. Its history predates the formal corporation: Casio's own timeline says Kashio Seisakujo was founded in Mitaka, Tokyo, in April 1946, and that Casio Computer Co., Ltd. was established in June 1957 as the development and production company for its relay calculators. The current corporate profile gives the formal establishment date as June 1, 1957 and lists headquarters at 6-2 Hon-machi 1-chome, Shibuya-ku, Tokyo 151-8543. Casio's current major products include timepieces, calculators, electronic dictionaries, label printers and electronic musical instruments, with individual product families such as G-SHOCK and other watch lines maintaining their own marketing and support content.
The company's portfolio has changed considerably over time, so discontinued categories from older company descriptions should not be presented as current core businesses. Product support is organized by country and product category. Casio's global support pages ask customers to select their location and product family for manuals, software, repairs and service information, and local Casio sites publish region-specific telephone or web contacts. The corporate headquarters telephone listed in the company profile is not a universal product-support line. Customers should therefore identify the model and purchase market before seeking warranty or repair assistance.
Watch products, calculators and musical instruments can have different service networks, parts policies and warranty terms, and purchases through an independent retailer may also be subject to that seller's return policy before manufacturer warranty service applies. Casio publishes official social-media account directories by region and product brand; these are appropriate for verifying genuine company accounts but should not replace support channels for account, order or repair issues. The company's long history means counterfeit or lookalike products are a recurring concern, especially around popular watch families.
A logo or marketplace listing is not sufficient evidence of authorized distribution, and consumers should use Casio's official country sites and known retailers for product and service information. It should not be approximated again; the correct fix is to obtain authentic current vector or sufficiently high-resolution brand artwork from Casio or a reliable official media source. The durable Profile details are the 1946 engineering roots, June 1 1957 establishment of Casio Computer Co., Ltd., Shibuya headquarters, Japanese electronics identity and casio.com global domain.
