❓ Frequently Asked Questions
How do I search the Japanese lexicon? ▼
Type Japanese characters, Romaji, or an English meaning into the search box. The lexicon searches word titles, Romaji and readings simultaneously. Use the script and language pills to narrow results further.
What is the difference between Kanji/Kana and Romaji entries? ▼
Kanji/Kana entries show the word in native Japanese script — ideal for learners building reading skills. Romaji entries use Latin letters to represent pronunciation — useful for absolute beginners. Both include meanings.
What does Gojuon (五十音) order mean? ▼
Gojuon is the traditional Japanese syllabary order, similar to alphabetical order for hiragana: あ, い, う, え, お … か, き, く… This makes it easy to browse words the way Japanese dictionaries are organized.
Can I save words and practice them as flashcards? ▼
Yes — click the ♡ heart button on any word card (login required). Saved words appear on your Favorites page where you can review them like flashcards. A confetti animation confirms each save!
How do I use the "Starts with" filter? ▼
Type a hiragana character (e.g. あ), katakana, or a Romaji letter (e.g. "ka") to see only words beginning with that sound. This is great for focused practice on specific syllables.
