Top Popular Languages in Japan

Japan is a country with a rich culture and history, and its language plays an important role in defining its identity. Japanese is the official language of the country and is spoken by the vast majority of the population. The language has a unique writing system, which includes three scripts – kanji, hiragana, and katakana.

English is the most commonly spoken foreign language in Japan and is widely studied as a second language in schools. It is used in business and tourism and is essential for communication with people from other countries. Many companies in Japan require their employees to have a good command of English, and the language is also used extensively in international trade.

Chinese and Korean are also widely spoken in Japan due to the significant number of immigrants from these countries. These languages are used in business and trade, and many Japanese people also learn them to communicate with their business partners. Spanish, Portuguese, and French are also gaining popularity in Japan, particularly among younger people who are interested in learning new languages and exploring different cultures.


How To Pick Outstanding Translation Partners? 

Selecting the right translation services in Japan can be challenging. Here are some factors to consider:

  • Rate: Translation cost is a main factor in any business decision, but it should not be the only one. You should choose a translation partner who offers competitive pricing without sacrificing quality.  
  • Reviews: It is needed to look for translation services in Japan with excellent reviews and feedback from previous clients. Let’s check their website, social media, or third-party review sites such as ProZ, GoodFirms, and to see what others are saying about their services. Don’t be afraid to ask for references or samples of their work.
