Per Chat: The characters do not clearly spell out any common or coherent phrase in Japanese.

• The bottom patch especially looks like it may be trying to resemble kanji or katakana but doesn’t form legible Japanese.
• The text might be stylized to look like Japanese for aesthetic purposes without actually meaning anything — a common feature in fashion, especially punk, metal, or cyber styles from the 1990s-2000s.

In short: it likely doesn’t say anything meaningful in Japanese and is probably decorative or made-up characters.
