I am wondering --- nevertheless my language-setting is "Japanese", why "Pinyin" input appear.
"Pinyin" input is not necessary for almost all of the Japanese people.
It is not really a problem. But I am eager to know the reason. Please clear up my doubt.

I love Japanese people and the sound of your name! Nevertheless, I'm not sure why this is showing up for you. You should be able to disable it in apps though (Settings--Apps--All), locate and then select disable. That may get it out of your way.

Good luck!!
