I'm working as a sushi chef right now. And my point of view is to be able to become one. Is does require a bit of training and lot of hard work and the most important is love. Because some where along the line you will be face a very big challenge. Such as a customer comment and co-worker. Because sushi chef is the kind of job the all the customer can see the way you work and it extremely require a lot of multi- tasking skill. But nothing is impossible if we try hard enough. I'm still keep trying everyday I would said that be a sushi chef is not that easy but it the same as try to be a good chef that is not easy either. It does had a school to attend and learn a basic knowledge. Like the one that I graduated from " sushi chef institute" but still after graduated you will feel like you got a basic down. And when you start working in the sushi bar it all about speed, clean, and the quality of your final product. My experience when I got a job interview they will look at the quality of your sushi, how fast you can make it, the cut of the fish, and finally how you skill at " fillet fresh fish". I think if you love sushi go for it. But if you want to do it because you learn from somebody that this path going to earn a lot of money. Then don't because it not going to be a lot of money when you start ^^ so god luck
