Default GS4 - SC-04E (Docomo) - Osaifu Keitai installation

Hello,

I'm planning to root the phone and install a custom ROM on my Docomo GS4. But I'm worried that I might not be able to use the Osaifu-Keitai application. This is one the most used purposes of my phone.
I heard that it is not possible to install Osaifu-Keitai in other deivces, although they have NFC, like Nexus 5.
Has anybody installed and used Osaifu-Keitai on a custom ROM?

Cheers.
