Traditional paper dictionaries have been used by people since many years ago. Because they are printed – they are a reliable source of the most accurate and detailed explanations for words and sentences.  Here are our recommended paper dictionaries for Japanese learners.
 Kodansha’s Communicative English-Japanese Dictionary
Widely referenced as the most comprehensive English-Japanese dictionary available. It has an all-inclusive word bank of 22,000 words with the support of 190,000 sample questions. It includes Japanese translations for common words, technical terms, and even slang. Additionally, phrasal verbs, specific expressions, idioms, and related grammar points are also included. Most importantly, there is furigana to ensure users the ease to read.
In conclusion, this is a well-rounded paper dictionary suitable for all levels of Japanese learner.
Kodansha’s Furigana Dictionary
If you are an absolute beginner in Japanese and would like a dictionary that matches your beginner level. We recommend you use this. It is a basic English-Japanese and Japanese-English dictionary with 30,000 applicable basic Japanese words.
As its name suggests, there is always furigana on top of every kanji in the dictionary to assist the user as they read.
Despite having a smaller word bank, the explanations for each term are precise and comprehensive. For example, words are explained with thousands of examples of sentences. Differences in the usage of similar words are clarified in the dictionary. In conclusion, this is the first Japanese dictionary for beginners.

Electronic Japanese Dictionaries

If you feel that it is too troublesome flipping through thousands of pages on a paper dictionary, you may consider getting an electronic one.
Electronic Japanese dictionaries are portable, fast and with useful features such as kanji writing recognition and integrated audio. Some may also have multiple dictionaries stored. This allows you to avoid the trouble of carrying a heavy book around.
Electronic dictionaries have one big weakness – most Japanese electronic dictionaries are built for Japanese English learners. Therefore, the user interface is in Japanese most of the time. If you are a beginner in Japanese, we do not recommend you to get one. (Jump to online dictionaries and apps)
The price of an electronic dictionary depends on its features and the number of dictionaries stored. While older models with basic functions cost less than 40 US dollars, some newer models have more features and bigger word banks are priced up to $500.
Because of the convenient translation websites and apps today, it is almost pointless to spend money on simple electronic dictionaries. As such, we advise you to purchase a newer model with better features. Specific models we recommend is Casio’s ED 9800 Series. It is the comprehensive English-Japanese dictionary series with the latest features. The latest model has the largest word bank supported by 20 English-Japanese dictionaries and 11 Japanese-Japanese dictionaries.

Online Japanese Dictionaries and Apps

If you are looking for an easy solution that is also free – we recommend you use an Online dictionary / App dictionary.
Online dictionaries and apps only need require your phone or laptop and an internet connection (some are even available totally offline). They are extremely convenient, easily accessible and are suitable for most people.
