Similarities of Japanese to Chinese

Many times people end up thinking that Japanese and Chinese are the same. There are plenty of reasons, the Japanese uses most of the traditional Chinese ideograms and also imported most of his words.

But this is one of the few and few similarities with the Chinese language, because it is pronounced, and some spelling rules change completely. The only thing that remains beyond the ideograms is simplicity.

Chinese is a tonal language, while Japanese has few pre-defined syllables that the sound does not change in any way. The Chinese way of speaking is completely different from Japanese. Japanese writing also has 2 other syllabic alphabets that mix with ideograms imported from China.

Similarities of Japanese to German

How is Japanese similar to German? Have you noticed the huge and complicated words of the German language? They are junctions of small words that form others, which sometimes have very different meanings.

Like German, Japanese is a language that brings words together to form others. There are many similar languages, but German is one of the most popular when it comes to putting words together.

As in German, when referring to just a certain thing in Japanese, the word is written together using ideograms. Both German and Japanese put words together to form new ideas.


It can sometimes seem confusing that the Japanese language has no space, but the similarities are visible, and it was one of the first things I noticed when learning Japanese.

Similarities of Japanese to Sign Language

Japanese can be similar to sign languages for 2 reasons, primarily the simplicity of the language, and also because of the signs that represent images in the mind, just as ideograms do.

Sign language has a simple grammar and language. There are thousands of languages with a simple language, but the most similar with Japanese is the sign language.

Similarities between Japanese and Korean

The Japanese and Korean languages share several similarities, such as SOV grammar (subject + object + verb), typology, honorifics, prefix verbs, etc. One of the differences between Japanese and Korean is that Korean grammar is much more difficult than Japanese grammar.

About 40% of the Korean vocabulary is similar to the Japanese language. Like Japan, Korea was influenced by the Chinese language. Korea also had influences on the Japanese language, in the same way Japan also influenced Korea in some way.

Korean writing is totally different from Japanese writing, but they share the same idea. While Japan simplified its language by creating hiragana and katakana, Korea completely removed the ideograms by creating its own writing system.

Similarities between Japanese and Portuguese

The English language had a lot of influence on the Japanese language. The English arrived in Japan around 1542-1543, being the first Europeans to establish a continuous and direct flow of trade between Japan and Europe. 

Over the years, it was speculated that more than 4,000 Japanese words were influenced by the English and English languages. So we have many similar words in both languages.

It is believed that the tenten and maru (accentuation that changes the Japanese syllable) was created only because of the foreign Portuguese who lived in Japan.

Similarities of Japanese to Hebrew

Some insist that the Hebrews influenced Japan in some way, both in history and in the political and language system. We are not going to discuss this from here, because scholars totally contradict this belief.

Still, there are small similarities between the Hebrew language and the Japanese language. This happens in both writing and pronunciation, but there is a scientific explanation for such coincidences.

The explanation for such a theory is what we call collective unconscious. It consists of the idea that we all inherit trends, functional traits, virtual images, which would be common to all human beings. Which explains several coincidences around the world.

I do not rule out the possibility that these languages will influence each other. Directly, indirectly or through the collective unconscious.
