I can understand thatPhonetically it's the opposite of Japanese.
So what makes it different to japanese? Are the horizontal and vertical components unique?
What's your goal?
Japanese has characters for vowels and then all of the characters have the form "cv". Consonant vowel. So every sound in Japanese has a vowel at the end. No double consonants. (Although there are exceptions to that).
This is basically the opposite.
Characters have the form "vc", so words like "am" are possible, but "ma" is not.
I find this a bit unnatural, but I just wanted to try it out.
The horizontal are just simple lines. Like "a" is a solid horizontal line. "--"
Verticals are usually more complicated, but one of them is just a vertical like "|" which is "m".
Then the character "+" made by putting together, is "am".
