On their FAQ page it says when answering ‘What is Crunchyroll Expo?’:

“Crunchyroll is the largest anime streaming company in the world, and we have our own convention! Crunchyroll Expo (or CRX) brings anime fans together for three days of exhibits, screenings, panels, and guest appearances by some of the biggest personalities in the US and Japan. Crunchyroll Expo is a showcase of the best of what Japanese animation and pop culture has to offer – as well as unique elements, events, and experiences never seen before at an anime con. Join us for a celebration of anime, manga, games, guests, cosplay, and so much more!”

This is 100% accurate …but there is still so much more!

Crunchyroll Expo is more than just an anime convention — it’s where everything you love about anime and the fan community come together in one location for three amazing days.
