Japanese carrier KDDI/Au released ezplus as part of their EZweb set of standards for mobile telephony. It is based on Java ME extended with proprietary APIs. The first device supporting it was released on 2001 (Hitachi C451H). ezplus was later renamed to "EZ-appli (Java)" (Japanese : "EZアプリ (Java)") and gradually replaced with a BREW-based solution called "EZ-appli (BREW)" until 2004 when the last ezplus device was released.

In 2006 an Open Application Player (Japanese: オープンアプリプレイヤー) feature was added allowing to run MIDP 2.0 Java apps on the BREW devices, which were often denominated as オープンアプリ. It lacks support for the original proprietary extensions of ezplus. On 2011, Open Application Player was updated and renamed to "EZ-appli (J)" along EZ-appli (BREW) which became "EZ-appli (B)"

Applications were denominated "ezplus アプリ" (during the ezplus name era) and come in the form of .KJX files

Overview

EZweb-enabled phones were given the ability to run J2ME applets in July 2001. The applets, originally known as ezplus before being renamed EZ-appli (EZアプリ) in 2003 where grouped by "phases" until 2005, when KDDI switched from J2ME to competitor BREW (although a means of running J2ME applets through BREW was offered).
