I'm curious about trademark issues WRT the company having the same name as a well-known Nintendo character. IANAL, and I know that the context in which a name is used affects whether or not the name is protected, but I've got to think that if (for example) I started an extremely not-video-game-related company named "Pikachu" that I would likely get some heat for it, even if it was just a toothless nastygram from a lawyer asking me nicely to not use the name. Is the name "Yoshi" not as protected for whatever reason (more common name/word/etc.), or is this just a case where the company is in a different industry therefore Nintendo's protection doesn't apply, or is this a risky thing to do? I'm just genuinely curious about how this stuff works, I have no stake in any of it. It's a great name and I wish the startup the best.
