Married in Japan and UK. Divorced in Japan, not yet in UK

Hello,
Firstly, I very much appreciate the opportunity to pick your brains.
I was married in both the UK and Japan. We decided to divorce last summer after being separated (me moving back to the UK in May 2018),
It is amicable. One son lives with me, my other two children live with her. I own the house there and contribute to the mortgage.
Divorce in Japan is very simple. Stamp some forms, agree what you will do, fill them in and submit them. It is done. I'm not saying it's perfect, far from it, but simple it is.
Now for the UK. Will I need a translation of the Japanese divorce documents to proceed, or will this be separate? Do I proceed in a different way? I have no idea.
Any advice will be greatly appreciated.
Kind regards,
Lee

If you were validly divorced in Japan you do not need to get another divorce in the UK. In fact you should not be able to get a divorce in the UK because if you issued a divorce petition here you would have to disclose on that petition that you have previously been divorced in Japan. That would stop a UK divorce in its tracks. No, the fact is that if you ever need to prove you are divorced (by, for instance, seeking to remarry in the UK) you should only need to provide an official copy of the Japanese divorce together with a certified translation. That divorce would be recognised here. There is a specialised office within the structure of marriage registration which checks foreign divorces if a registrar is unsure. There is no reason to suppose your Japanese divorce wouldn't get the necessary tick of approval.

Wow! That is excellent news. So, I am divorced in both countries already. I will just a get translation done to prove it.
Thanks very much for your help. I have searched high and low on the internet and it doesn't state the fact clearly anywhere. I felt that I may need to register the divorce somewhere, but obviously not.
Your help is very much appreciated.
Kind regards,
Lee
