Unshō Ishizuka (Japanese: 石塚運昇 May 16, 1951 – August 13, 2018) was a Japanese voice actor for the Pokémon anime.
Biography
Ishizuka was born on May 16, 1951, in Katsuyama, Fukui, Japan. He became a voice actor in 1984, becoming known for his deep, strong voice, which led to him being typecast as older and more mature male characters. His most notable roles in the Pokémon anime are that of Professor Oak and the unseen narrator. He died on August 13, 2018, of esophageal cancer. However, he managed to record his parts for episodes all the way to October. Following his death, archive audio for Ishizuka has been used for Sophocles's Charjabug, Toucannon, and Tapu Bulu. His prerecorded narration was featured posthumously in M22.
