@Masahiko_Nagata, a Japanese translation template file is now available on Github.
Thank you!
If possible, can you get an English version QM file too?
I want to edit with linguist and check how the display will be displayed with SimuCUBE Configuration Tool on my PC.
I hope downloading from DropBox etc …
All the dialog text fields should scale if the translated text is shorter/longer, so there should be no need for checking if things fit or not.
In Qlinguist the qm files would not help, we would need to share dialog UI files, which we will not do.
