Japanese Dictionary Guide

Below is a comprehensive list of the best Japanese dictionaries and translators available in today’s market. A solid Japanese – English dictionary is handy if you’re looking to learn Japanese or if you wish to understand more about Japanese culture.

There are many ways to learn Japanese. Whether it is an online Japanese language course, a school manual, a native Japanese author of language training support, or a manual for all levels (from beginner to intermediate), the difficulty lies in choosing an effective method.

Best Japanese Dictionaries

The Japanese language is more complex than any language. Its dictionary should focus on ideograms and Japanese characters such as Katakana and Romaji. That’s why a good dictionary is essential when you learn Japanese.

Here are some recommendations for Japanese dictionaries to help you choose the right tool for you.

1. The Denshi Jisho (電子辞書)

The best option is to buy an electronic dictionary like the Casio Ex-word data plus as many of them are trilingual and can have in the same device 17 different dictionaries including English, Spanish, Japanese, and two versions of the Encyclopedia Britannica. 

In addition, this is best as it can be both a Japanese-English dictionary and an English-Japanese dictionary.

2. Dictionaries Apps for Android & IOS.

A go-to choice for today’s Japanese language learners is dictionary apps for your phone. It’s light, handy, and way cheaper than buying a bulky dictionary.

It’s best to download the apps on both your phone and iPad.

Our recommended dictionaries apps include Midori, a great bilingual dictionary with many example phrases for each Japanese word you look up, and the official dictionary of Kodansha: The “Kanji Reader’s Dictionary,” which is the electronic version of the paper dictionary.

3. Traditional Dictionaries

A good bilingual dictionary must not only have the translation of the word you want to search for, but it must also have example sentences in which the pragmatic use of the unknown word is contextualized.

Therefore it is recommended to buy a bilingual dictionary published in Japan because they are the same as the ones we can find in the Casio electronic dictionaries. We recommend “The New Nelson Dictionary,” with Japanese and English renderings.

This dictionary has two versions, the compact edition and the “Bible” edition, which by size occupies the same as the complete edition of the Lord of the Rings in a single volume.

If you are an intermediate learner or determined to study Japanese in-depth, this is a necessary purchase as it contains 32,000 entries and 7000 characters. It is a dictionary designed for English-speaking students.

The Best Japanese Romaji Dictionary

RomajiDesu is a free online English Japanese or Japanese English dictionary that contains the following tools for Japanese learners:

  • English-Japanese dictionary: A powerful and easy-to-use bi-directional English-Japanese dictionary where you just need to type your word into a single input in Japanese (Kanji, Hiragana, or Katakana), Romaji, or English and you’ll get definitions as well as example sentences.
  • Kanji dictionary: This includes a powerful Kanji search form and a multiple Kanji radical search method.

  • Waeijiten (わえいじてん | Japanese-English dictionary)
  • Kokugojiten (こくごじてん | Japanese-language dictionary)
  • Kanwajiten (かんわじてん | Kanji-Japanese dictionary)

Japanese Dictionaries Types

Before we go over the list of dictionaries below that you can use for your language learning, let’s make sure you’re familiar with the other types of Japanese dictionaries.

  • Hyakkajiten(ひゃっかじてん | encyclopedia)
  • Kogo Jiten(こごじてん | traditional Japanese dictionary)
  • Gendaigo Jiten(げんだいごじてん| modern Japanese dictionary)

  • Denshi Jisho(でんしじしょ | electric dictionary)
  • Zatsugaku Jiten(ざつがくじてん | trivia collection)

How are Japanese dictionaries organized?

The majority of Japanese dictionaries are organized alphabetically by kana spelling. It is organized in go-juu-on (五十音) order, which means “fifty-sounds. This method arranges these characters as a table with five column vowels for every ten rows of consonants, for a total of 50 table cells.

Japanese Gojuon Table

As you can see, the five columns a-i-u-e-o (あ-い-う-え-お) are positioned at the head of the table. To be clear, it’s not a-e-i-o-u like in the Latin alphabet, but rather a-i-u-e-o. Sounds strange, right?

The ten rows include the consonant-free row, and the consonants k, s, t, n, h, m, y, r, and w. Once again, it’s strange, but it’s how it works in Japanese. Don’t worry; you’ll get used to it!

Note: The fifty sounds aren’t precisely fifty, and n (ん) doesn’t fit any place in the table; thus, it stands out more than the rest.

Other Japanese Dictionaries

Today’s Japanese learners have many options to choose from. You can effortlessly search for and download an app online with just one press. However, the more options you have, the better.

We have listed down additional dictionaries. Check them out to see if one of them fits your language learning style.

Japanese Translation Tools

Do you want to understand the meaning of a Japanese word/sentence/phrase right away? Then, below we have compiled several free online translators that, among other languages, work well with Japanese.

This way, you will get quality translations to understand everything from a simple message from your group of friends to an excerpt from a book.

Google and Microsoft

Two of the most popular online translators are Google and Microsoft. Google Translate stands out for its support for dozens of languages, including Japanese. It’s the easiest tool.

It provides how it sounds as well as the meanings. However, it’s not a completely precise translation. It gets a bit messier when you input long or complicated sentences. Try to break it down into shorter and simpler sentences to avoid trouble.

If you’re not a native English speaker, you might feel like you want to translate Japanese to your language or the other way. Though I strongly recommend sticking Japanese to English to avoid mistranslation.

You can also search or paste words or texts, speak aloud or attach documents. In addition, its mobile app allows you to translate images or posters through its camera.

Microsoft Translator has also improved a lot over the years. It allows you to translate text and audio, documents, text fragments, and websites.


DeepL is an online translator that supports several languages, including Japanese and Chinese. It can translate text fragments or entire documents.

Among its unique features, it allows you to refine the translation of each word when searching for synonyms by context. In addition, it learns with each new translation, and we can use it in any connected browser, from a computer, tablet, or smartphone.

To use DeepL, you only need to copy and paste a text fragment, and the result will be displayed in seconds.


Baidu Translator supports dozens of languages, including Chinese and Japanese and English and Spanish. They can translate from one language to another. And although its default interface is in Chinese, it is easy to understand the layout of the buttons and forms.

In addition, the languages to choose from can be selected in Chinese or English. Baidu’s translation is fast and effective. Just copy and paste the text. You can also play audio of the text to be translated and/or the translation.

Digital Dictionary or Analog Dictionary? It’s your choice!

In this digital era, we can travel freely with mobile dictionaries. But paper dictionaries have many advantages for studying a language in their way. If you want to purchase Japanese dictionaries or books, Books Kinokuniya(きのくにや), Amazon.jp, GOYOKIKIYA(ごようききや), and other similar sites might be a great help to you.

Wrap Up

In conclusion, whether you opt for a digital or analog Japanese dictionary, the choice ultimately hinges on your personal preference. What truly matters is selecting a dictionary that resonates with you and meets your needs. Regardless of the format, having a reliable dictionary at your disposal can be a game-changer in various scenarios.

It’s not just a tool for language learners; it’s a gateway to a world of knowledge and understanding. So, go ahead, choose the dictionary that feels right for you, and embark on your exciting journey to explore the depths of the Japanese language!
