15 Best Indonesian Translation Apps & Tools [2025 Comparison Guide]

“I’m traveling to Indonesia, but I’m not confident about communicating in Indonesian.”

“In meetings with Indonesians, I’m so focused on listening that I can’t take notes.”

“I’m not sure if my Indonesian is actually understandable.”

Do any of these concerns sound familiar? If you use Indonesian in your daily life or work, you’re not alone.

With the growing number of Japanese companies establishing factories and branches in Indonesia, as well as the increasing population of Indonesian workers in Japan, many people are struggling with Indonesian communication.

For those facing these challenges, we recommend using Indonesian translation tools, apps, and websites.

Why Indonesian Translation Apps and Tools Are Essential

There are three main reasons why Indonesian translation apps and tools are in high demand:

1. The Number of Indonesian Speakers Is Growing

Indonesian has approximately 200 million speakers, roughly double the number of Japanese speakers. Indonesia’s population continues to grow and is expected to exceed 300 million by 2032.

Furthermore, Indonesia’s economic growth is remarkable, with GDP projected to rank 7th in the world by 2030 and surpass Japan by 2035. Given this backdrop, opportunities to communicate with Indonesians will only continue to increase.

2. The Number of Indonesian Workers in Japan Is Increasing

Indonesian workers number 121,507, making them the 5th largest group among foreign workers in Japan. According to the Ministry of Health, Labour and Welfare, Indonesian workers increased by 156% year-over-year, representing the highest growth rate among all nationalities.

This is largely due to the impact of the “Specified Skilled Worker” system that began in April 2019, making it easier for foreigners to work in Japan.

3. There Is a Shortage of Indonesian-Japanese Translators

Despite growing demand, there are very few translators and interpreters proficient in both Japanese and Indonesian. Even when you can find a qualified Indonesian-Japanese translator or interpreter, the fees tend to be quite high.

Using translation tools and apps is a more affordable and practical solution.
