locale.Error: unsupported locale setting

If I set my $LANG to the following:

LANG=ja_JP.UTF-8

the following error will occur

Traceback (most recent call last):

If I use LANG=en_US.UTF-8, everything's OK.

Is ja_JP.UTF-8 installed on your computer?

$ locale -a | grep ja_JP

I was able to replicate the error on my Arch laptop and had to go through this process (link) to get it working. We could improve RTV to catch the exception and print a more descriptive error message, but this sounds more like a system configuration issue to me.

You're right. When I do locale -a, ja_JP.UTF-8 is not there. I forgot uncommenting this line in /etc/locale.gen

ja_JP.UTF-8 UTF-8  

After I uncomment it and rerun sudo locale-gen, rtv starts without any error.
