Poorly written Japanese button text

[maekawa-mugi]

Emoji has several Japanese buttons, but the characters they contain are poorly written.
I am Japanese, but it is difficult to explain in English.
🈯:Totally poor.
🈚:The bottom four points must not be placed in an arc.
㊗️,㊙️:The left and right radical of kanji are too far apart.
🉐:The "日" in the upper right corner is too large.
🈳:Poor Contrast.

Also, most of the characters is not snapped to the top and bottom center.

Dear @maekawa-mugi, many thanks for pointing this out! As we don't have a clue about these Japanese buttons (nor can the team read/write Japanese) ... it would be great if you could provide a PR and fixes on them.

If anyone would like to take on this task, the following may prove helpful:

Here is a list of Japanese characters that appear in emojis:
ココ,サ,月,有,指,得,割,無,可,申,合,空,祝,秘,営,満

And for inspiration, here is a comparison of how they appear in several rounded sans-serif typefaces:

Zen Maru Gothic

Kosugi Maru

M PLUS Rounded 1c

Resource Han Rounded

Resource Han Rounded looks the most natural.

As Korean which uses Chinese characters(/or kanji /or hanja), I also understand the problems. Those emojis look quite unnatural.
