Chinese and Japanese share characters, a geographical area and a reputation as difficult languages. Beyond that, everything separates them: grammatical structure, pronunciation, writing systems, professional opportunities. Choosing one over the other means first understanding what truly distinguishes them.
What the two languages actually have in common
The most widespread misconception is believing that Chinese and Japanese are closely related because they share characters. This visual similarity conceals a very different reality.
Japanese borrowed Chinese characters (called
hanzi in Chinese,
kanji in Japanese) in the 3rd century. This borrowing was purely graphic: the two languages have no genetic relationship. Chinese belongs to the Sino-Tibetan family. Japanese is a language isolate, with no established linguistic family.
What they concretely share:
- A large number of kanji/hanzi that are identical or very similar in form
- Borrowed words of Chinese origin present in Japanese (on’yomi, Sino-Japanese reading)
- Vertical writing is possible in both languages
- No phonetic alphabet at the base: both languages are learned through characters
What they do not share: grammar, tones, phonology, and everyday vocabulary as a whole.
Grammar: advantage Chinese
Mandarin Chinese grammar is often described as one of the simplest among major languages. Verbs are not conjugated. There is no grammatical gender. No marked plural. Tense is expressed by time markers (yesterday, tomorrow, already) rather than verb endings.
Japanese grammar is more complex. Verbs are conjugated according to tense, mood and level of politeness. Japanese has an elaborate system of politeness registers (
keigo) that changes the form of verbs and nouns according to the relationship between speakers. Word order is Subject-Object-Verb, the opposite of English.

Pronunciation: advantage Japanese
Mandarin is a tonal language with four tones. The same sound pronounced at a different pitch completely changes its meaning. The word
ma (妈/麻/马/骂) can mean mother, hemp, horse or insult depending on the tone used. For an English speaker who has never practised a tonal language, this is the most destabilising challenge of Chinese.

Japanese has no lexical tones. Its phonology consists of simple syllables (consonant + vowel). There are five vowels, as in Spanish or Italian. For an English speaker, Japanese pronunciation is largely intuitive from the first few weeks.

Writing: two different challenges
Chinese uses only one writing system: characters (hanzi). A level of fluent reading requires approximately 2,000 to 3,500 characters. This is a significant investment, but a single one: only one thing to learn.
Japanese uses three systems in parallel:
- Hiragana (ひらがな): phonetic syllabary of 46 syllables, the basis of written language
- Katakana (カタカナ): second syllabary of 46 syllables, used for foreign words and certain technical terms
- Kanji (漢字): characters of Chinese origin, approximately 2,136 in the official Japanese standard (jōyō kanji)
A typical Japanese text mixes all three systems in the same sentence. Each kanji generally has two pronunciations: an original Japanese reading (
kun’yomi) and a Chinese-borrowed reading (
on’yomi). A character like
山 is read
yama (mountain in native Japanese) or
san (Chinese borrowing), depending on context.

Hiragana learned in a few weeks |
The advantage of Japanese: hiragana and katakana can be learned in two to four weeks. From that point, any Japanese text can be decoded phonetically, even without understanding the kanji. In Chinese, every unknown character is an opaque wall.
Professional opportunities
Choosing a language for professional reasons deserves an honest look at the market.
Mandarin Chinese is the mother tongue of more than one billion people. China is the world’s second-largest economy and the leading trading partner of many countries in the sectors of trade, logistics, manufacturing and new technologies. Demand for Mandarin-speaking professionals remains structurally high and underserved.
Japanese is the language of Japan, the world’s third-largest economy. Sectors in which Japanese is a real asset include technology (robotics, semiconductors, video games), automotive (Toyota, Honda, Nissan), culture (manga, anime, gastronomy) and tourism. Japanese is less spoken outside Japan, making it a more targeted differentiating advantage.

Transfer of learning: does learning one help with the other?
This is the question that few comparisons address. The answer is asymmetrical.
Learning Chinese first significantly facilitates the subsequent learning of Japanese. The reasons are concrete: Japanese kanji are largely Chinese hanzi (often slightly modified in their traditional or simplified form). A Chinese speaker visually recognises a large proportion of kanji from the outset. Understanding radicals (components of characters) is directly transferable.
Learning Japanese first helps far less for Chinese. Kana (hiragana and katakana) do not exist in Chinese. Japanese grammar is very different from Chinese grammar. And the tones of Chinese still need to be acquired from scratch.
If the goal is to learn both languages eventually, starting with Chinese is the strategy that maximises overall return on investment. To explore this path further, online Chinese courses allow you to lay the foundations of characters and tones before tackling Japanese.

One piece of advice is unanimous among experienced learners: never start both at the same time. The writing systems and sounds mix together. The brain cannot build two such different structures simultaneously without them interfering with each other. Choose one, reach a B1-B2 level, then tackle the other.
