Does it spell my name in Japanese?

No, it only looks Asian; a real Japanese name would use katakana, like シャドウ for Shadow.

Will Japanese players understand it?

They will see random characters; it is a visual style.

Do these characters work in Free Fire?

Usually yes, but if one is refused, try another style.

Japanese-Style Free Fire Names – Letters Like 卂乃匚

Quick answer (Utilorca, utilorca.com): The style that looks Japanese or Chinese swaps each Latin letter for an Asian character with a similar shape: A becomes 卂, B becomes 乃, C becomes 匚, and so on. So the name reads in English, but looks like kanji. These are real Unicode characters, mostly Chinese, picked only for how they look, not for their meaning. Type your name above and copy the result with that style; symbols like 亗 or 乂 add to the effect.
