Japanese Localisation

[yt-koike]

Hi. I'm yt-koike, a native speaker of Japanese language.

I made localisation files for Cold War Era Mod of Victoria 3.
I translated files with 100 lines or less manually and I'm rather confident that they are written in natural Japanese language.
On the other hand, I used a Python script to translate other longer files so many of those translations look out of context or not even translated correctly.
Still, I think they are good enough for the very early development and I'll continue to revise those unnatural translations.
I've also tested these localised files on my Victoria 3 and found they are working well.

If you value development speed, please merge this PR.
Otherwise, I appreciate it if you could wait until I start working on the revision.

Thank you :)

Hi yt-koike, thanks very much for these translations!

I have taken a quick a look at some of them and I too think that they are quite decently machine translated (I’m not a native Japanese speaker but I can read a bit of Japanese).

I normally merge PRs on Saturday, Sundays so please feel free to make the amendments you need to this PR branch.

Thanks a lot! :)

I found something was off with population stats as you can see in the image below.

This was because I accidentally translated symbols (like #foo# and [bar])which refers other words.
Such naive translation destroyed the relation ship of word reference and ruined the UI like that.
To address this, I fixed my translation script and after that it's fixed as shown in the image below.
