About AMOS
AMOS Origins
Taiyo Chemicals Corporation, known for its AMOS brand of mahjong products, was established in 1954 in Wakayama Prefecture. Initially specializing in urea resin products, the company began manufacturing and selling mahjong tiles during Japan’s mahjong boom in the 1960s. These tiles were made using the same urea resin technology originally developed for imitation pearls.
Innovation in Automatic Mahjong Tables
In the 1980s, AMOS entered the field of automatic mahjong table development. At that time, most machines from other manufacturers lacked operational stability and were prone to mechanical issues. Their designs were also utilitarian, prioritizing function over form.
Despite entering the market later than its competitors, AMOS introduced streamlined plastic frames and continuously refined its machines to minimize mechanical errors. Since the release of its first automatic table in 1988, AMOS has spent nearly 40 years pursuing better, more reliable products. Today, AMOS stands as a leader in the Japanese mahjong product industry.
AMOS in Pop Culture and Professional Play
AMOS models such as the AMOS MATER and AMOS ULTIMA inspired the designs featured in the popular anime Saki. The company has collaborated with TV Tokyo since the early stages of the series.
AMOS is also the official supplier for Japan’s professional M.League, providing the REXX 3 model. This table features advanced technology to eliminate tile-mixing bias—an unseen but critical innovation that enhances the precision and fairness of top-level matches.
Global Reach
Since the 2020s, AMOS has been working to bring high-quality Japanese mahjong products to a global audience. In particular, the company has taken steps to comply with U.S. regulations, including adjustments for radio frequency and voltage compatibility, to ensure safe and reliable product performance.
AMOS FESTIVAL
AMOS also organizes the AMOS FESTIVAL—an event dedicated to sharing the excitement of mahjong and offering memorable experiences for fans and players alike. The festival features new product announcements and provides opportunities for AMOS Automatic Mahjong Table owners to connect and interact.
Through AMOS and Riichi Mahjong, the event aims to foster a sense of excitement and satisfaction by bringing people together through the shared joy of the game.
