LESSON 1
Double consonants, long vowels & family terms
促音・長音 — sokuon, chōon
pause long vowel palatal

Three things in this lesson change how kana sound on the page: the small , long vowels, and the kinship terms built from them.

The small つ促音 sokuon

To mark the short, sharp pause inside a double consonant, write a small . It is roughly half the size of a normal つ, is silent on its own, and doubles the consonant that follows it.

kitte
postage stamp
gakkō
school
kippu
ticket
zasshi
magazine
The pause borrows the sound of the next consonant, so きって is held kit·te, never ki·tsu·te.

Long vowels長音 chōon

Two patterns stretch a vowel long. A kana ending in o followed by makes a long ō: おとうさん is otōsan. A kana ending in e followed by makes a long ē: せんせい sounds like sensē.

arigatō
thank you
sensei
teacher
tokei
clock / watch
gakusei
student
By convention most dictionaries, and your book, still romanise that long ē as ei: せんせい is written sensei. Trust the kana for the sound, not the romaji.
A few native words lengthen e with instead of い: おねえさん (onēsan) and ええ (ē, meaning yes). Long a, i and u exist too, written ああ, いい, うう, as the family terms below show.

Addressing older family家族 kazoku

Older relatives are addressed with set kinship terms, wrapped in the polite お…さん. Younger relatives are usually called by name or nickname instead.

father
otōsan
father
mother
okāsan
mother
older brother
onīsan
older brother
older sister
onēsan
older sister
Each one hides a long vowel: とう → tō, かあ → kā, にい → nī, ねえ → nē. The sister term is the え exception.

Takeaways

Read each example aloud until it is smooth, then tap Hide readings and test yourself. If a raw kana still feels slow, drill it in the practice app first.
