uzumaki = whirlpool
naruto = food u get in ramen that looks like a whirlpool
mostly all names in animes/mangas resemble items or food. take dbz as example.
though in dbz names are also underwear.
the names have always meant something translated into japanese...it is a manga, a lot of the time the names can be a link to the character for example people who have something to do with water can have sui in their names like the uchiha that drowned shisui (dead water) or suigetsu or otherwise it could be a reference to an ability or just a coincidence.
