Batik plays multiple roles in the culture of Indonesia. The wax resist-dyeing technique has been used for centuries in Java, and has been adopted in varying forms in other parts of the country. Java is home to several batik museums. On 2 October 2009, UNESCO inscribed written batik (batik tulis) and stamped batik (batik cap) as a Masterpiece of Oral and Intangible Heritage of Humanity from Indonesia. Since then, Indonesia has celebrated a Batik Day (Hari Batik Nasional) annually on 2 October. In the same year, UNESCO recognized education and training in Indonesian Batik as a Masterpiece of Oral and Intangible Heritage of Humanity.
