Do I need to fill out the Kokuseki Sentaku Todoke?

I'm 25 and never choosey nationality (I didn't know I had to do it myself, I thought the Japanese government would contact me).

I've lived in the UK my whole life and never had a Japanese passport. But recently decided I want to get one.

However I've been researching dual nationalitys and find myself in abit of a crossroads.

Can I apply for the passport without filling in the kokuseki sentaku todoke and still get it?

Will the act of me applying for the passport kick off the process in which I need to fill out the Kokuseki Sentaku Todoke.

I should mention I have no interest in actually renouncing my UK citizenship.
