Learning Japanese can be a challenge, but thanks to technology, there are incredible tools that make the process easier. Browser extensions are especially useful, allowing you to learn while browsing the internet. In this article, I present a detailed list of the best extensions to learn Japanese directly from your browser, with recommendations for different levels of learning and needs.
Table of Contents
Mainichi (毎日): Expand Your Vocabulary Daily
The Mainichi extension is a simple and efficient way to increase your Japanese vocabulary. Whenever you open a new tab in Google Chrome, a Japanese word appears accompanied by:
- Kanji, hiragana, or katakana (depending on the word).
- Translation in English.
- An associated image, which helps with visual memorization.
With Mainichi, you learn new words every day, integrating learning into your daily life.

Other Essential Extensions
1. Rikaikun: The Instant Translator for Japanese
Rikaikun is essential for anyone browsing Japanese websites. With a simple hover over a Japanese word, it displays:
- Pronunciation of the kanji (in hiragana).
- Translation in English.
- Related words.
Ideal for intermediate and advanced students who need support while reading news, manga, or any online content.
2. IPA Furigana: Read Kanji with Ease
If you are still learning kanji, IPA Furigana is a fantastic extension. It adds furigana (pronunciation in hiragana) over the kanji on any page you visit.

- Facilitates the connection between kanji and its correct pronunciation.
