How many kanji do you need to learn to master Japanese?

The question of how many characters to learn often frightens those who are beginning Japanese. We hear talk of thousands of symbols and the goal seems unattainable. However, it’s not necessary to know everything in order to speak, read manga, or manage during a trip. Let’s look at the real figures and set concrete objectives.

The official figures: the Jōyō Kanji list

The Japanese Ministry of Education has established a standardised list. It’s called the Jōyō Kanji (常用漢字, じょうようかんじ), which literally means “kanji for common use”.

This list contains exactly 2,136 characters. This is the standard expected of a student at the end of secondary school in Japan. If you know these 2,136 symbols, you can read the newspaper, administrative documents, and the vast majority of books without needing a dictionary.

This represents a considerable volume. It’s the final objective for complete mastery of written Japanese. But for a foreign learner, aiming for this figure from the start is a strategic error. Progress in learning kanji happens in stages.

Daily reality: how many for 90% comprehension?

Linguistic statistics show us a more encouraging reality. The frequency of character appearance isn’t linear. Some kanji appear in almost every sentence, whilst others appear only once a year.

Here’s the statistical breakdown of reading coverage:

With just 1,000 characters, you already understand 90% of what’s written in a newspaper or on a website. The remaining 10% can often be deduced from context or looked up quickly. For a traveller or expatriate, knowing the 500 most frequent ones already radically changes daily life.

Learning stages: the JLPT system

The official Japanese Language Proficiency Test, the JLPT (Japanese-Language Proficiency Test), divides learning into 5 levels. It’s the best barometer for setting your objectives.

Level N5: Survival basics (80 – 100 kanji)

This is the first step. Here, we learn numbers, days of the week, directions, and basic action verbs.
Typical examples:
– 一 (ichi, one), 二 (ni, two), 三 (san, three)
– 人 (hito, person)
– 日 (hi/nichi, day/sun)
– 食べる (taberu, to eat)
– 行く (iku, to go)

At this stage, you can read prices, dates, and very simple sentences.

Level N4: Daily life (approximately 300 kanji)

By adding 200 characters to the previous ones, you reach N4 level. The vocabulary expands with terms related to family, weather, and simple social situations.
Examples:
– 家族 (kazoku, family)
– 兄弟 (kyōdai, brothers and sisters)
– 雨 (ame, rain)
– 勉強 (benkyō, study)

Level N3: The bridge to autonomy (approximately 650 kanji)

This is the pivotal level. With 650 kanji, you begin to read simple manga (those with furigana, the small reading aids) and understand simple blog articles. You leave the “beginner” zone.

Level N2: Professional level (1,000 – 1,200 kanji)

This is often the level required to work in Japan. With just over 1,000 kanji, you’re functional in a standard professional environment. You’ve reached the 90% comprehension threshold mentioned above.

Level N1: Expert level (2,000+ kanji)

This level corresponds to the complete Jōyō Kanji list, plus some additions. It’s the level necessary to read complex literature, academic or legal articles.

The 80/20 rule applied to ideograms

The Pareto principle applies perfectly here: 20% of kanji produce 80% of meaning. You mustn’t learn characters randomly or in dictionary order.

Focus on “radicals” and building kanji. For example, the tree kanji 木 (ki) is fundamental. Once acquired, you find it everywhere:
– 林 (hayashi): the grove (two trees).
– 森 (mori): the forest (three trees).
– 休む (yasumu): to rest (a person 人 against a tree 木).

Learning intelligently means identifying these elementary building blocks. A complex character is often just an assembly of simple kanji you already know.

Proper names and special cases

There’s an additional difficulty: surnames and first names. The Japanese government authorises an additional list called Jinmeiyō Kanji (人名用漢字, じょうようかんじ), specifically for names.

These characters aren’t always useful for reading the newspaper, but they’re very frequent on business cards or film credits. For example, the surname “Tanaka” is written 田中 (Rice field + Middle). These are two very basic kanji. But other names use rare readings or ancient characters. Understanding these specificities is an integral part of discovering Japanese culture, where names often carry meaning related to nature or local history.

Should you know how to write them or read them?

This is a modern distinction that must be taken into account. In the digital age, we write by hand less and less. On a smartphone or computer, you type phonetically (rōmaji) and the software suggests the correct kanji.

Your absolute priority should be recognition (reading).
Knowing that 憂鬱 means “melancholy/depression” (yūutsu) is useful. Knowing how to write it from memory stroke by stroke is much less so, because even many native Japanese forget and use their phone to check.

Don’t block your progress because you can’t memorise the exact stroke order of a complex kanji. If you can recognise it in a sentence, move on to the next one. You’ll return to manual writing later if you wish to perfect your calligraphy.

Concrete strategy for getting started

To avoid drowning in the mass, here’s a simple method for your first 100 kanji:

1. Numbers (1-10, 100, 1000, 10000): They’re simple and immediate.
2. Natural elements: Fire (火), Water (水), Earth (土), Sun (日), Moon (月). These are also the days of the week.
3. Directions: Up (上), Down (下), Left (左), Right (右), Middle (中).
4. Major action verbs: Eat, Drink, See, Listen, Speak.
5. Opposite adjectives: Big/Small (大/小), New/Old (新/古).

Set yourself a goal of 2 to 3 kanji per day. In three months, you’ll have covered N5 level.

The importance of context

A kanji on its own rarely has a unique meaning. Its reading changes depending on what surrounds it.
Take the sun kanji: 日.
– Alone, it’s read “hi” or “nichi” (the sun, the day).
– In “Sunday” (日曜日), it appears twice and is read differently: nichi-yō-bi.
– In “Japan” (日本), it’s read ni (Nihon).

Don’t learn readings by heart in isolation (“On-yomi” and “Kun-yomi”). Learn complete words.
Learn that “Japan” is called “Nihon” and written 日本. This is much more effective than trying to remember all the theoretical pronunciations of the character 日.

The number of kanji to learn therefore depends entirely on your objective. For tourism, 100 are sufficient. To live there, aim for 1,000. To read everything without hindrance, the path to 2,000 is long but fascinating. Start small, be consistent, and the symbols that seem like indecipherable drawings today will soon become familiar words.
