Jay Kabira is a Japanese actor and voice actor born September 23, 1962 in Okinawa Prefecture, Japan. He is affiliated with the talent agency K Factory. One of his notable early voice acting roles is in the 1989 anime OVA Cipher, where he provided the voice for the twin brothers Siva and Cipher, also known as Jake and Roy Lang. The OVA is noted for being dubbed entirely in English by a predominantly Japanese cast, and Kabira's performance has been described as a decent effort that remained in character even for the production's making-of feature.

Beyond Cipher, Kabira performed narration for the 2018 anime series Middle Management Rookie Rrootakahara. He has also contributed his voice to the tokusatsu genre, most prominently in the 2025 series Kamen Rider ZEZTZ, where he voices the character Zero. His voice acting work continues into related projects, including Kamen Rider ZEZTZ: Transformation Classroom in 2025 and Kamen Rider Nox: Transformation Classroom in 2026.

Kabira's career spans both acting and voice acting across film, television, and stage. His screen acting credits include appearances in the 1989 film Gunhed and the 2005 series Garo. In 2025, he took on a leading role in the series Kamen Rider ZEZTZ. While his voice acting roles are a component of his professional work, his broader career as a performer includes significant live-action work in Japanese television and film, demonstrating a consistent presence in the entertainment industry from the late 1980s through the present day.
