JUSCO (ジャスコ, Jasuko^?) is the acronym for Japan United Stores Company, a chain of "general merchandise stores" (or hypermarket) and the largest of its type in Japan. The various JUSCO companies are subsidiaries of ÆON Co., Ltd..

The JUSCO name was adopted in 1970 by a company originally founded as a kimono silk trader in 1758. Renamed ÆON in 1989, it operates stores throughout Japan under JUSCO and other names and also has a presence in Malaysia, Hong Kong, mainland China (永旺 Yǒng wàng), and Thailand.

As of March 1, 2011, all JUSCO and SATY stores under the Aeon umbrella in Japan officially changed their names to AEON while all the JUSCO stores and shopping centres in Malaysia are fully re-branded into AEON since March 2012. However, JUSCO stores still operate in the Greater China region and some others.

In 1985 the first JUSCO overseas store was opened, in Plaza Dayabumi, Kuala Lumpur, Malaysia, as a jointly-owned company with Cold Storage and three local companies. It was the first time that a Japanese company had entered into a significant joint venture in the Malaysian retail industry. JUSCO assumed total operational control of the chain in 1988. Currently. there are 20 AEON (formerly known as JUSCO) Retails stores and shopping centres are in operation in Malaysia.
