This article is about a character featured in the Pokémon anime who has not yet debuted in the English language dub. As such, their information may contain romanized Japanese names, rather than dub names.
Professor Sakuragi debuted in a fantasy in SS001. He physically debuted in SS002 during the opening ceremony of Sakuragi Institute, where he explained his goal of studying everything about Pokémon to better understand them and the world itself. During his speech, Sakuragi received an alert of changes in the atmosphere, leading him to predict the appearance of a rare Pokémon at the Vermilion harbor.
Later, he was impressed after hearing Ash and Go's findings after their encounter with the rare Pokémon, Lugia, and offered the two to become research fellows at his lab, which they accepted. Afterwards, Sakuragi offered Go to choose one of the Kantostarter Pokémon, but Go declined, wanting to make Mew his first Pokémon instead.
In SS003, Sakuragi gave Ash a smartphone before releasing his two Rotom from their Poké Balls. The Rotom proceeded to enter Ash and Go's smartphones, turning them into Rotom Phones.
Professor Sakuragi is a calm, but friendly person. He is very knowledgeable about Pokémon, being deemed a genius since he was young. He is also exceptionally enthusiastic when it comes to studying Pokémon. Sometimes, he gets so carried away that it embarrasses his daughter, prompting her to reign him in.
