Juli Erickson was an American voice actress best remembered in the One Piece fandom for voicing Tsuru and Kokoro, alongside decades of English-language anime dub work.
In the English dub of One Piece, Erickson gave voice to two supporting characters: Tsuru, a stern Marine officer who oversees discipline within the Navy's ranks, and Kokoro, the eccentric, sake-loving mermaid stationmaster tied to the Water Seven arc. Her casting reflected the gruff, seasoned character work she was known for across the anime dubbing industry.
Beyond One Piece, Erickson built a long résumé in English-language anime dubbing, most notably voicing Pinako Rockbell in Fullmetal Alchemist and appearing in Evangelion: 1.0 You Are (Not) Alone, Basilisk, Samurai 7, and Ouran High School Host Club. Her on-screen acting credits included a small part in Michael Cimino's Heaven's Gate plus television guest spots on Matlock and Walker: Texas Ranger, and she later starred as Apollonia Kowalski in the 2010 Holocaust drama Esther's Diary. She stepped away from voice acting in 2018 and passed away in December 2025 at age 86.
