A Report from the Public Dubbing Event

A public dubbing event took place somewhere in Tokyo Wednesday June 15th.
Present on stage were Kanata Hongo, the voice of Soji, Shiori Sato, the voice of Makoto, Koichi Yamadera, the voice of Marshadow, Shoko Nakagawa, the voice of Joy, Arata Furuta, the voice of Bonji, and Director Yuyama.



Sato went to see the very first movie in the theater as a child. This time, she plays the lively and masculine Makoto.
She had trouble getting the running scene right, and had to practice it many times.

Hongo liked Pokémon so much as a kid he wouldn't go play outside on the days it aired on TV. He performs his role as Soji, the boy with a calm exterior hiding true passion, with great skill.
He spoke of his role with the line "I can now die without any regrets", which made the other actors laugh heartily.



Nakagawa is playing in her 11th Pokémon movie this year, and performs a passionate portrayal of Joy, whom she greatly admires. Her performance was so perfect the director even called it "the very image of Joy".
"I've made use of my 11 years of experience and the director's words in every single moment of my life to turn my entire life into Pokémon", she said with passion in her voice.



Furuta was told to "make his performance more excited" and instantly switched gears, playing a Bonji that was profound, yet at the same time overflowing with excitement. Furuta has said he doesn't use his natural speaking voice when voice acting, but he did exactly that this time, and commented that "It actually made me feel really awkward".

Yamadera has played in 20 movies in a row so far, and this time he's in charge of Marshadow's voice. "I have less lines this time than I've ever had before, but it's also my most difficult role so far", he said. He goes on to say he tried various methods in order to follow the difficult instructions he was given, like "It shouldn't sound normal, it shouldn't sound like a voice" and "Make the sound come from your respiratory tract". During the dubbing, he gave us a strange tone of voice that contained both two and three sounds at the same time, which impressed everyone present, the director included.

The session concluded with everyone playing a finger pointing game based on the movie's title "I Choose You!": "If you had to choose one of the guest voice actors to be your travelmate, who would you choose?"
The guest voice actors went "Won't that just cause arguments later?" and "Are you really making us do this? (laughs)" with bitter smiles on their faces.
The end result was that Nakagawa, Yamadera and Furuta pointed to Hongo, Sato pointed to Furuta, and Director Yuyama pointed to Yamadera.

There's only one month left until the movie premieres! Make sure to check out the passionate performances from all the guest voice actors in the theater!!
