Japan and Nepal have increasingly close cultural, economic, and labor exchange ties. As of 2023, over 100,000 Nepali nationals reside in Japan under various visa categories, such as technical interns or care workers. However, Nepali is not commonly supported on many mainstream Japanese translation tools, and vice versa. This language gap affects everything from applying for jobs and handling immigration paperwork to making doctor’s appointments or just talking to locals.
Yet, most popular apps overlook this language pair. If you’re a Nepali immigrant, traveler, or businessperson, this guide will help you choose the best tool for your needs.
Don’t Download Yet! Look for These 5 Features First
Not all apps are created equal. When evaluating options, we recommend looking for the following features:
- Offline translation support (important for travelers without mobile data)
- Voice input and output for real-time communication
- Text and photo translation capabilities
- Language pair support with high accuracy (Japanese ↔ Nepali, not via English as a bridge)
- User interface in Nepali or Japanese
