Personal life When asked by a reporter about receiving the nickname "the Throwing Philosopher," Imanaga replied (through an interpreter) "I know that I have a unique personality. If I'm trying to say a normal thing, it comes out a little sophisticated." Prior to starting his MLB career, he said at a press conference (through an interpreter), "I am by no means a finished product and there is a lot [for] me to learn, and there is a lot for me to study day-in and day-out. And I believe that, somehow, my approach in that way earned me the nickname."

When asked how he felt pitching in New York for the first time, Imanaga replied (through an interpreter) "The view from the hotel, I recognize it from Spider-Man. So I was just like, oh, this is where Spider-Man was."

Imanaga nicknamed himself "Mike" because of the difficulty baristas at Starbucks had pronouncing his name. The nameplate on his locker was changed to read "Mike Imanaga II"; the "II", according to Imanaga, "just sounds cool".
