What’s so poignant about this bit of news isn’t the casting change, it’s the story behind it.
On X (formerly Twitter), fans were soon aware of a special bond between Yamazaki and Okamura. Some years back, when Okamura was on maternity leave and Nami still featured in One Piece, it was Yamazaki who filled the void, for just a while giving voice to the cherished character.

It’s understandably nostalgic, and now Okamura returns the gift working in for Yamazaki as Ran Mouri, almost like a life story where friendship pays it forward.

Yamazaki is scheduled to appear in the 2026 film Detective Conan: The Fallen Angel of the Highway, as she recorded everything for it before going on hiatus.

The team will aspire to full recovery for Yamazaki and eventually her return, putting her health as the priority.
