Using Naruto word on game?

Hi guys, I’ve plan to make Naruto guessing character game, but I still not sure about Naruto’s trademark.
Naruto is one of the biggest manga, it has a lot of fans.
is it save if I using “Naruto” word? I see other publisher using “Naruto” word on google play store. How to find information about copyright and trademark of the product?

Thanks
