​​Introduction to uc-locale-ja_JP-12.5.0.1-31.cop.sgn​​

This localization package enables full Japanese language support (ja_JP) for Cisco Unified Communications Manager (CUCM) 12.5 environments. Designed for compliance with Japan’s industrial standards JIS X 0213:2024, it implements yen currency formatting (¥), era-based calendar display (Reiwa 7), and vertical text rendering capabilities for XML services.

Compatible with Cisco 8800/8900 Series IP Phones and Webex Room Kits deployed in Japanese enterprises, this COP file follows Cisco’s cryptographic signing standards for secure deployment. The package was officially released on March 28, 2025, as part of CUCM 12.5 SU3 maintenance updates.

​​Key Features and Improvements​​
