I am located in the New York State.
Thank you for providing your state name, KuroDubs.
Under both Japanese copyright laws and US copyright laws, most fandubs will violate the law if they are made without the authorization of the copyright holders. Copyright laws in both countries protect copyrighted works from being reproduced or distributed or displayed/performed by others and both countries give the copyright holder the exclusive right to prepare derivatives (like translations).
To acquire permissions, you would need to contact each of the copyright holders whose work you wish to use and inquire about licensing rights in their works. For the works you are considering, there are many copyright holders (writers, illustrators, publishers, developers ...) and you would need to make sure that you have contacted any and all who hold rights to what you want to use.
There are some uses of copyrighted material that can fall within the US Copyright Act guidelines for "fair use" but rarely would commercial uses of another's works be considered a fair use. In addition, fair use is an affirmative defense to a copyright infringement action and not permission to use copyrighted works. This means that if you are having to defend your use as a fair use, you have probably been sent a settlement demand letter by a copyright holder or you have been sued by a copyright holder. You want to avoid this.
You can have your plans reviewed by an IP attorney in New York. Personal reviews are often necessary to better determine whether a specific use of rights-protected material could be viewed as infringing on anyone else's rights.
Good luck.
