I think Koizumi is my favourite "public figure" at Nintendo currently. By "public figure" (I don't know what other term to use) I'm talking about commonly-recognized higher-ups like Miyamoto, Aonuma, and Doug Bowser.
Anyway, I don't know why, but Koizumi just has this friendliness and joyfulness around him that I can sense anytime he's on camera. I love his story-driven work in games like Super Mario Galaxy and I think he did great work on Odyssey and the Nintendo Switch. There's also
this video of him playing 1-2 Switch at the console launch with a little boy, and it's just the most adorable thing ever.
Don't get me wrong, I like Shinya Takahashi on Directs too, but man... every time Koizumi is the presenter, I always get even MORE hype.
