PM2019 68 Press Release

After 12 years since her last appearance in the Pocket Monsters anime as Shigeru, she returned to voice Satoshi's rival in the episode Rivals for Go?! The Road to Mew!! In an interview tweet by the official Japanese anime PR, she said she was very nervous when she entered the studio to play Shigeru for the first time in a long time but when she heard Satoshi's voice, voice by Rica, which has always remained unchanged, she naturally came back to Shigeru.

It's been about 12 years since Shigeru last appearance, so I was as excited as everyone else. I was very nervous when I entered the studio to play Shigeru for the first time in a long time, but...
When I heard Satoshi's voice, which has always remained unchanged, I naturally came back to Shigeru.
He has always had a bit of a superiority complex as a character, but I think this time he will bring a different kind of charm that everyone will notice. I'll be happy if you'll pay attention to his passionate attitude toward his goals. Yuko Kobayashi as Shigeru
