The JLPT for Indonesian Speakers: What Transfers, What Doesn't, and Where to Spend Your Time

Indonesian speakers usually sound good in Japanese from the first week. Then the grammar and kanji arrive, and progress slows. The two languages sound alike, while their word order, grammar and writing are far apart.

The Head Start You Already Have

Japanese has five vowels, a, i, u, e, o, and Indonesian uses the same five. Most Japanese syllables end in a vowel, as many Indonesian ones do. So words like 子こども or 友達ともだち come out clearly without special practice, and romaji reads almost the way you would read Indonesian.

Katakana loanwords are another gift. A lot of them come from English, and many Indonesians already know the English word: テレビ, コンピューター, ホテル. Once you can hear the English word inside the katakana, these become easy points.

Four Contrasts to Get Straight Early

Each row is a habit from Indonesian that pulls you the wrong way in Japanese.

PointIndonesianJapanese
Word orderSaya makan nasi.私わたしはご飯はんを食たべます。
Place and directiondi rumah / ke sekolah / dari Jakarta家いえで / 学校がっこうに / ジャカルタから
PastSaya sudah makan.食たべました。
Siblingskakak / adik兄あに・姉あね / 弟おとうと・妹いもうと

Word order. Indonesian puts the verb in the middle; Japanese saves it for the end. In long sentences you have to hold the whole thing in your head until the verb arrives, and in listening that is tiring until you get used to it.

Particles come after the word. di, ke and dari go before the noun. で, に and から go after it. Say 学校に, never に学校.

Siblings. kakak and adik don't say whether the person is male or female. Japanese has four words and also changes them when you talk about someone else's family (お兄さん, お姉さん). The JLPT tests this at N5 and N4.

Verbs Change Shape in Japanese

In Indonesian, makan stays makan. You show time with words like sudah, sedang or akan. Japanese changes the verb itself: 食べます, 食べました, 食べて, 食べない, 食べたい. A large part of N5 and N4 grammar is learning these shapes.

The rules are regular once you know which of the three verb groups a verb belongs to. Learn the groups first, then each new form is one rule per group instead of a new list. Our verb groups guide starts there.

There is a useful bridge for the transitive and intransitive pairs (開く/開ける). Indonesian marks the same idea with affixes, as in terbuka and membuka, so the concept is familiar even when the Japanese endings are new.

The Two Sound Traps: Long Vowels and Small っ

おばさん / おばあさん

aunt / grandmother. Only the vowel length is different.

きて / きって

come / stamp (or cut). Only the small っ is different.

In Indonesian, holding a vowel longer doesn't make a different word, and double consonants are rare. In Japanese both change the meaning, and the JLPT listening section often uses these pairs as wrong options. Practise by clapping the beats: おばさん is four, おばあさん is five. The long vowels and small っ guides have drills.

Kanji From Zero

Chinese and Vietnamese speakers arrive with thousands of kanji-related words already in their heads. Indonesian speakers don't, and that is the main reason kanji takes longer.

Three habits help. Learn each kanji inside a word you already say (駅 as えき rather than as an isolated character), start with the ones you see every day, and study look-alikes on purpose, since you have no older habit that tells 待 from 持. Budget daily time for kanji from the start instead of leaving it for the end.

Politeness: A Familiar Idea

Indonesian already separates formal and casual speech: Anda and kamu, bahasa baku and everyday speech. Japanese does the same with です・ます and the plain form, and later with keigo. The idea transfers; what you learn is where Japanese draws the line. Start with です・ます everywhere, as the JLPT does at N5 and N4, and add the plain form when you reach it.

What I Would Do in Your Place

  1. Use your pronunciation head start in listening, but drill long vowels and っ separately, because your ear will not catch them for free.
  2. Learn the three verb groups before you collect more forms.
  3. Give kanji a fixed slot every day from the first month.
  4. Say sentences with the verb at the end out loud until it stops feeling backwards.
  5. Register early. In Indonesia account creation opens before registration itself; the Indonesia registration guide has the dates and cities.

Ringkasan dalam Bahasa Indonesia

Pengucapan bahasa Jepang relatif mudah bagi penutur bahasa Indonesia karena vokalnya sama. Tantangan utamanya ada di urutan kata (kata kerja di akhir), partikel yang diletakkan setelah kata benda, perubahan bentuk kata kerja, dan kanji.

Perhatikan vokal panjang (おばさん / おばあさん) dan っ kecil (きて / きって), karena keduanya sering muncul di soal choukai. Sisihkan waktu untuk kanji setiap hari sejak awal.

Questions Indonesian Students Ask

Is Japanese hard for Indonesian speakers?

The sounds are easy: Indonesian and Japanese share the same five vowels and similar open syllables. The hard parts are verb-final word order, particles after the noun, verb conjugation and kanji. Kanji is usually the biggest single hurdle, because Indonesian has no character background to lean on.

Where can Indonesian speakers take the JLPT?

In Indonesia the JLPT is run through one national registration site, jlptonline.or.id, with test cities across the country. Our Indonesia registration guide lists the cities, fees and the registration window.

Which JLPT section is hardest for Indonesian speakers?

Usually the vocabulary and grammar booklet, because of kanji and conjugation. Listening tends to be the most comfortable section, though long vowels and small っ still cost points.
