Shizu is back with a Japanese Hiragana Katakana writing notebook!
You have to use Japanese a lot and learn it to become immersed in the Japanese characters.

There is a Korean proverb that says, “Habits formed at age three last until eighty.” There is a similar saying in Japanese that says, “Your personality as a child does not change as you get older.”
To write correctly and beautifully in Japanese, you must learn and write hiragana and katakana correctly from the beginning.
In Korean, one character called 'Hangeul' is used, but in Japanese, three characters are used.
Also, unlike Hangul, which creates a single letter by combining 'consonants' and 'vowels', each Japanese letter has a single sound.
If you memorize the pronunciation of each letter accurately and learn just a few pronunciation rules, you can read Japanese sentences without difficulty.
Until you have completely memorized hiragana and katakana, I recommend keeping the 50-syllable chart close by and studying by looking up unfamiliar characters.
