If there are Roman Catholics, are there Japanese Catholics, Israeli Catholics, Sudane

If there are Roman Catholics, are there Japanese Catholics, Israeli Catholics, Sudanese Catholics & the like?

You're playing with words: all Catholics are Roman Catholics.

Umm...yeah...there are Japanese people who are Catholic, but they don't call themselves "Japanese Catholics" and I'm sure that goes along with the others you have listed.

Nope, they are called Roman catholics because the Catholic faith is based in Rome.

I dunno.

All Catholics are most certainly NOT Roman Catholics.

Roman Catholics follow the Pauline doctrine and are cent red in Rome.

Coptics follow a Catholic path from out of Egypt.

The Celtic faith (once the largest of the Catholic faiths) is making a comeback in Scotland.

Plus there are Greek Orthodox, Russian Orthodox, Ukrainian Orthodox, and most would say Anglicans.

All are Catholic without being Roman.

There are American Roman Catholics, Japenese Roman Catholics, Israeli Roman Catholics and Sudanese Roman Catholics..... Then there are Catholics of the Eastern Rite and such which are considered part of the Catholic Church.

The Catholic Church is comprised of Patriarchal Sees, which belong to a specific Rite, and each of these Sees are in union, both in terms of Faith and Temporal Structure, with the Patriarch of Rome who functions as the Servant of the Servants of God and the Successor to Peter as the head of the Bishops of the Church.

A Rite is the form of Liturgy used as well as particular cultural aspects of that Church that developed out of the culture that was evangelized as well as the specific apostle who went to them.
