Welcome to Nico
What I woud of done if I were you to ask the Japanese dealer who sold you the car to take care of it. If they need your business they can probably do it lot easier.
Here in Canada we have 3 languages available to the G. You can switch on the screen. Spanish, French and English. Europian infiniti's going to have even more languages for sure. I'd say German, Russian and maybe few more. I don't think Nissan is that stupid to make it special for each country. Not cost effective at all. Should be just a software update. I would imagine it is possible. Only matter of finding the right place and the right person.
We have a regional forum with quite a few members from Japan. Maybe they can help you out with this. Try to post there too.
If nothing else try a japanese nissan forum or Nissan HQ Japan. I am sure you are not alone with this situation.
Here is our regional forum.

Good luck. If you have any info please get back to us with it. So we can help others also.
Andy might can help you too. He is located in Australia and I believe his car is from Japan. Not sure tho. You might want to pm him.
Here is his profile.
