In Japan, there are 3 writing systems:
Egyptian writing was called hiroglyphs. It first had 700 symbols then rose to 6,000 symbols.
There are around 1,000 unique cuneiform symbols that were used in ancient Mesopotamia for writing various languages like Sumerian and Akkadian.
There are three writing systems in Japanese: kanji (characters borrowed from Chinese), hiragana, and katakana. There are over 2,000 commonly used kanji characters, along with 46 characters in both hiragana and katakana.
Cuneiform writing was used by ancient Mesopotamian civilizations and was characterized by wedge-shaped symbols pressed into clay tablets. Phoenician writing, on the other hand, evolved into the modern alphabet and was more linear and simplified compared to cuneiform. The Phoenician alphabet later became the basis for many other writing systems including Greek and Latin.
There were many known writing systems.
There are 10 symbols in the system and they are... 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0.
In a traditional haiku, the first line typically consists of 5 syllables, not symbols. The number of symbols can vary based on the writing system used (e.g., English, Japanese, etc.).
If you mean the type there is three : -HIRAGANA -KATAGANA -KANJI
Because every system was invented by a different culture.
There are many symbols for Japan, such as their flag, the Nisshōki (sun-disc flag); the Kyokujitsu-ki (rising sun flag); the Go-Shichi no Kiri (government seal); the Cryptomeria; or the Chrysanthemum.
Symbols are universally understood across many languages. Also, using symbols rather than full names helps scientists to avoid the repetition of writing the long names of elements and atoms again and again.
The Japanese use three writing systems: hiragana (cursive), katakana (print), and kanji (borrowed from the Chinese).
