Toray entered the textile-trading business with synthetic fibers in Indonesia in 1948 under the Toray TETREX trademark. This marked the beginning of Toray business development in Indonesia.

Toward the end of the 1960s, the government of Indonesia began actively inviting foreign investment, including from Japan. Seeing the potential for a strong win-win situation, Toray decided to establish production bases in Indonesia. Beginning in the early 1970s, Toray established joint venture companies in the areas of Tangerang, Purwakarta and Ciracas.

In addition to producing the first synthetic fiber made in Indonesia, Toray also developed businesses in spinning, weaving and dyeing. In the Tangerang area, Toray developed a land area of 77 hectares, which was previously an area of rice fields and wetlands. The several factories located there attracted many workers from all over Indonesia. A strong foundation for Toray Group Indonesia was laid in the early 1970s thanks to good cooperation with the government and local communities, as well as the efforts of Toray employees.

Innovation and sustainable business development

Since the mid-1970s, Toray Group's investments in Indonesia have been designed to foster continuous business development and technology innovation. In the 1980s, with the TETREX trademark already widely accepted by the market, Toray began to develop “made in Indonesia Eexports, responding to plans for export promotion by the Indonesian government. Major customers in Europe and North America have assessed the quality of Toray Group Indonesia products as superior than competitor products from South Korea and Taiwan.
