associated with wealth and good fortune. The original logo was a heavily stylized version of the katakana characters for Toyota (). As the company started to expand internationally in the late 1950s, the katakana character logo was supplemented by various wordmarks with the English form of the company name in all capital letters, "TOYOTA." Toyota introduced a worldwide logo in October 1989 to commemorate the 50th year of the company, and to differentiate it from the newly released luxury Lexus brand. The logo consists of three ovals that combine to form the letter "T", which stands for Toyota. Toyota says that the overlapping of the two perpendicular ovals inside the larger oval represents the mutually beneficial relationship and trust between the customer and the company while the larger oval surrounding both of these inner ovals represents the "global expansion of Toyota's technology and unlimited potential for the future". The new logo started appearing on all printed material, advertisements, dealer signage, and most vehicles in 1990. In countries or regions using traditional Chinese characters, e.g. Hong Kong and Taiwan, Toyota is known as "豐田". In countries using simplified Chinese characters (e.g. China and Singapore), Toyota is written as "丰田" (pronounced as Fēngtián in Mandarin Chinese and Hɔng Tshan in Minnanese). These are the same characters as the founding family's name "Toyoda" in Japanese. Toyota still uses the katakana character logo as its corporate emblem in Japan, including on the headquarters building, and some special edition vehicles still use the "TOYOTA" wordmark on the grille as a nod to the company's heritage. On July 15, 2015, the company was delegated its own generic top-level domain, .toyota.
