Laravel Japanese character validation full width (Katakana & Hirakana )

I want to validate whether user's input is in full width (Katakana & Hirakana & alpha) characters or not?

I has saw Laravel Validation doc but cannot validate on my case. https://readouble.com/laravel/5.7/en/validation.html

anyone can give me an example for below? (input => validate)

1. full width only ckeck:

   'ぁァ1'　=> invalid,

   'ぁァ1あア１'　=> invalid,

   'あア１'　=> valid,

2. Half width only ckeck:

   'ぁァ1'　=> valid,

   'ぁァ1あア１'　=> invalid,

   'あア１'　=> invalid,
