The document summarizes Takayuki Okazaki's presentation on internationalization at JavaOne Tokyo 2012. It discusses how Java supports internationalization out of the box through features like Unicode, locales, calendars, encodings, and more. It also covers enhancements to internationalization in JDK7 like improved locale handling. Finally, it mentions some missing features in Java for internationalization like telephone number formatting and suggests using the libphonenumber library to address this.
