Casio Japan

Casio are one of the world's largest manufacturers of pocket calculators. The company was founded in Japan in 1946 (originally called Kashio Seisansho) and has its headquarters in Shibuya, Tokyo. As well as calculators, the company manufacturers a wide range of electronic equipment including electronic musical instruments, cameras and watches. The company was founded by engineer Tadao Kashio ('Casio' is an anglicized version of his name) who invented a cigarette pipe which became the company's first product. The compay then worked on other engineering product manufacturing until his brother Toshio suggested that they develop an electro-mechanical calculator. At the time electric calculators were essentially motorized versions of hand operated devices, but the new calculator was based instead on relay technology used in telephone exchanges. It was launched in 1954 and was the first to be manufatured in Japan. The company moved to electronic designs in 1965 with the launch of its first 'all-transistor' model, with integrated circuits taking over in the late 1960s, although electronic calculators were still large, expensive desktop devices. The first pocket calculators were the various versions of the Casio Mini, using six-digit vacuum fluorescent displays. Although they were just one of many calculator manufacturers in the 1970s, by the 1980s Casio was a technology leader launching the world's first graphing calculator, the Casio fx-7000G. Casio continue to be one of the largest calculator manufacturers, with their scientific models used widely in schools throughout the world.​

Citizen watches will be released in August from “The CITIZEN”, the highest peak of the Citizen brand, in August with two limited edition models that use Tosa Washi, one of the three largest Japanese papers on the dial. The product names. For durability, toughness, and classic style, shop G-SHOCK analog-digital and digital watches. Our digital watches withstand nearly any adventure you can think of with features such as water resistance up to 200 meters, shock proof, and more.

Calculators

CASIO’s integration of LSI technologies and skilled craftsmanship represent the quintessence of the manufacturing excellence for which Japan is recognized worldwide.

Constructed with genuine quality, CASIO products provide truly practicable applications in which functionality and beauty combine.
The leading-edge LSI technologies and skilled craftsmanship that give life to CASIO watches exemplify the quality Japan boasts in the world marketplace.
For CASIO, “faith in manufacturing” refers to an inexorable advancement of digital technologies and an uncompromising commitment to fine craftsmanship.
This faith engenders unparalleled performance that not only elevates CASIO watches as close as possible to perfection, but that actually changes their wearers’ lifestyles.

Metal moulding

The moulds employed for resin watch parts, from gears and other precision parts to novel moulded external parts, are originally fabricated at Yamagata CASIO. Besides undergoing many automated manufacturing processes, they are hand-polished to give them a precision finish.

Module manufacture

A single production line at Yamagata CASIO can handle assembly of as many as 13 types of movements, and the ability to perform speedy small-lot production of many products is among its strengths. Suitable for production of a diverse variety of watches, from watches with three hands to chronographs with multiple hands, the lines have the capacity to create an abundant lineup that enables customers to select a watch to suit their style.

Parts manufacture

Several microscopically sized rigid resin gears are installed in each movement. Minute teeth around the gears’ perimeters mesh with the teeth of other gears neither too gently nor too strongly to assure smooth movement. At Yamagata CASIO, these minute parts are made using machining technologies with 1/1000 mm precision to assure more accurate gear movement.

Quality assurance

Conducting everything from mould design and production to parts moulding, circuit board mounting and assembly in a highly integrated production system, Yamagata CASIO achieves high-quality product manufacturing.
An inspection system making free use of leading-edge sensing technologies to conduct precision examinations of parts quality by sensor is implemented in every process.
Only products that satisfy strict standards are sent out into the world.
