The official currency of Indonesia is the Indonesian Rupiah (IDR). The exchange rate fluctuates, but as a general reference, 1 Japanese Yen typically converts to between 95 and 105 Indonesian Rupiah. It is generally recommended to exchange only a small amount of yen (e.g., ¥10,000 to ¥20,000) at Narita or Haneda airport for immediate needs, then use authorized money changers in popular tourist areas.
Is it better to exchange yen for rupiah in Tokyo or in Bali? It is almost always more advantageous to exchange your Japanese Yen for Indonesian Rupiah after you arrive in Bali. The exchange rates offered at reputable, authorized money changers on the island are significantly better than those you will find in Japan or at the airports.
While Bali is a predominantly Hindu island, it is part of Indonesia, the country with the largest Muslim population in the world. This means that halal food is readily available and integrated into the culinary landscape. The official halal certification in Indonesia is issued by the Majelis Ulama Indonesia (MUI), and its logo is often displayed prominently in restaurant windows or on menus.
