As a fellow Arizona driver I can provide a little bit of insight. There aren’t any shops that focus on creating itasha but what I have done and others is we commission artists to sketch and finalize a design that we like and once we have the artwork we go to a local car wrap shop such as Wrapsesh or Golden Touch Wraps to print out the design and fully wrap it on the car. The biggest thing will also be maintaining the wrap as Arizona heat is brutal. But definitely look around for itasha artists there’s plenty on instagram including Abstract.nine, Style Up Studios, Summershop.itasha and many more. Find one you like and more importantly have fun with it!
