From N5 to N4: Bridging the Gap

Moving from N5 to N4 is less about learning brand-new grammar from scratch and more about stretching what you already know into slightly longer, more flexible sentences. The JLPT has five levels, from N5 (the easiest) up to N1 (the hardest), and N4 sits right next to N5 as the second-easiest level. So the jump is real, but it is a gentle one.

At N5 you built a foundation: particles like は, が, を, に, で, and the basic verb forms (ます form, ない form, た form, て form, dictionary form). At N4 you keep all of that and add a handful of new tools: the potential form for saying you can do something, the たら conditional for 'if / when', ながら for doing two things at once, and the first taste of the passive and the causative. This article walks you through each one so you know what to expect.

None of these forms will click overnight, and that is completely normal. Treat this as a map of the territory, not a checklist to finish by Friday. The goal is to get familiar with the shapes, meet them again in real sentences, and gradually make friends with them.

N4 is the second-easiest of the five JLPT levels, sitting directly above N5. In other words, if N5 was your first step onto the ladder, N4 is the very next rung, not a leap to the top.

In practice this means the vocabulary and kanji grow, and sentences get a little longer, but the way Japanese works stays the same. You are still using the particles and verb endings from N5; you are just combining them in new patterns. Because of that, reviewing your N5 basics is one of the most useful things you can do while starting N4.

Keeping this picture in mind helps with motivation. When a new form feels hard, remember that you are only one step above where you were, standing on ground you already know.

The potential form lets you say that you are able to do something. For ichidan (ru-) verbs, replace る with られる: 食べる (taberu, to eat) → 食べられる (taberareru, can eat), 見る (miru, to see) → 見られる (mirareru, can see).

For godan (u-) verbs, change the final -u sound to -e and add る: 書く (kaku, to write) → 書ける (kakeru, can write), 話す (hanasu, to speak) → 話せる (hanaseru, can speak), 飲む (nomu, to drink) → 飲める (nomeru, can drink). The two irregular verbs have set forms: する (suru, to do) → できる (dekiru, can do), and 来る (kuru, to come) → 来られる (korareru, can come).

One small point learners often meet: with the potential form, the thing you can do is frequently marked with が rather than を. For example, 日本語が話せます (Nihongo ga hanasemasu) means 'I can speak Japanese.' Do not worry about mastering this on the first try; just notice it when it appears and try building a few sentences of your own, like コーヒーが飲めます (I can drink coffee).

The たら form expresses 'if' or 'when' — it sets up one thing happening, then something that follows from it. You make it by taking the plain past (た) form of a verb and adding ら: 食べる → 食べた → 食べたら (tabetara, when/if I eat), 行く → 行った → 行ったら (ittara, when/if I go).

For example, 日本に行ったら、寿司を食べます (Nihon ni ittara, sushi o tabemasu) means 'When I go to Japan, I will eat sushi.' Notice how に marks the destination 日本 and を marks the direct object 寿司 — those are the same N5 particles doing their usual jobs inside a longer sentence.

You can also use たら with adjectives and nouns, but at the start it is enough to get comfortable with the verb pattern. Try finishing sentences like 時間があったら… (if I have time…) in your head; that habit helps the pattern feel natural over time.

The ながら form lets one person do two actions at the same time. You make it from the ます-stem of a verb plus ながら: 聞く → 聞き → 聞きながら (kikinagara, while listening), 食べる → 食べ → 食べながら (tabenagara, while eating).

A very common example is 音楽を聞きながら勉強します (ongaku o kikinagara benkyō shimasu), 'I study while listening to music.' Here を marks 音楽 (music) as the object of listening, and the main action — studying — comes at the end. In this pattern, the ながら part is usually the smaller, background action, and the final verb is the main thing you are doing.

One thing to remember: ながら is for two actions done by the same person. If you can keep that single rule in mind, this form is one of the friendlier additions at N4.

The passive form lets you describe an action from the point of view of the person on the receiving end. For ichidan verbs, replace る with られる: 見る → 見られる (mirareru, to be seen), 食べる → 食べられる (taberareru, to be eaten). For godan verbs, change the final -u to -a and add れる: 言う → 言われる (iwareru, to be said/told), 読む → 読まれる (yomareru, to be read).

A friendly first example is 先生にほめられる (sensei ni homerareru), 'to be praised by the teacher.' Here に marks the doer — the teacher is the one who praises — while the subject is the person receiving the praise. Compare it with the active 先生がほめる (the teacher praises); the passive simply shifts the spotlight onto the one being praised.

You may notice that for ichidan verbs the passive and potential forms look the same (食べられる can mean both 'can eat' and 'is eaten'). That overlap is normal, and context usually makes the meaning clear, so there is no need to worry about it now — just meet the passive gently and let it settle in.

The causative form describes making or letting someone do something, from the point of view of the person who causes it. For ichidan verbs, replace る with させる: 食べる → 食べさせる (tabesaseru, to make/let eat), 見る → 見させる (misaseru, to make/let see). For godan verbs, change the final -u to -a and add せる: 書く → 書かせる (kakaseru, to make/let write), 行く → 行かせる (ikaseru, to make/let go).

A clear example is 子どもに野菜を食べさせる (kodomo ni yasai o tabesaseru), 'to make (or let) the child eat vegetables.' Here に marks 子ども (the child) as the one who is made to act, and を marks 野菜 (vegetables) as what is eaten. The subject is the causer — the parent, for instance.

Depending on the sentence and tone, the causative can lean toward 'make' (a bit forceful) or 'let' (giving permission), and context tells you which. At N4 you only need to recognize the shape and the basic idea; the finer shades come with more exposure over time.

The best way to grow into N4 is to build on the particles and conjugations you solidified at N5 and stretch them, one clause at a time, into longer sentences. Rather than memorizing each new form in isolation, try slotting it into a sentence you can already make. Take 音楽を聞きます (I listen to music) and grow it into 音楽を聞きながら勉強します — same particles, one new tool.

For a study rhythm, small and steady tends to be kinder than long, rare bursts. A few minutes most days — reviewing an N5 point, then meeting one N4 form in a real sentence — keeps the material fresh without overwhelming you. Some learners like keeping a tiny notebook of example sentences they meet in the wild; others prefer flashcards or shadowing audio. There is no single right method; pick what you enjoy enough to keep coming back to.

Finally, be patient with yourself. These forms are meant to be met many times, not conquered once. Approach them with curiosity, let context do a lot of the teaching, and enjoy the small wins — like the first time 日本語が少し話せます (I can speak a little Japanese) comes out of your own mouth.
