Romaji Drill
Learn Kunrei & Hepburn romaji
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Is でんしゃ spelled densya or densha? Both — it depends on which system you use.
Most people who struggle with romaji were never told that Japanese has two
romanisation systems. Kunrei-shiki is what Japanese schools teach;
Hepburn is what passports and station signs use.
When you spell a word in the other system, this app does not simply mark it wrong.
It tells you: "That is Hepburn spelling. In Kunrei-shiki it is densya."
■ Three ways to practise
・Pick — choose the correct spelling out of four
・Read — read the romaji and work out which word it is
・Write — spell it out on the on-screen keyboard
(ABC order or QWERTY; long vowels use the ô key)
■ Every mistake comes with the rule behind it
Spell it the other way and you are told "that is Hepburn spelling".
Write gakô for がっこう and you are told that a small っ doubles the next consonant.
Get it right and the rule is still shown. Nothing advances until you have read it.
■ Results point at rules, not just a score
Wrong answers are grouped by the rule you missed — double consonants,
long vowels, and so on — so you know what to look at next.
■ Practise in the system you need
・Kunrei-shiki — taught in Japanese schools (si, ti, tu, sya)
・Hepburn — passports and station signs (shi, chi, tsu, sha)
・Keyboard input — how you actually type (either spelling is accepted)
■ Nine topics
Basic kana, voiced kana, contracted sounds, double consonants, long vowels,
the n sound, everyday words, place names, and short sentences. 300 questions in all.
■ Romaji chart
All three systems side by side, with the rows where they differ highlighted,
plus the rules for っ, ー and ん.
■ Time trial
How many can you write in 3 minutes? A best score is kept per system.
