Hikashop Not Displaying Japanese Tab with Falang

-- url of the page with the problem -- : www.notavailable.com
-- HikaShop version -- : 2.3.2
-- Joomla version -- : 3.3.3
-- PHP version -- : 5.4.4
-- Browser(s) name and version -- : doesnt matter
-- Error-message(debug-mod must be tuned on) -- : Falang / Hikashop

So I bit the bullet and installed Falang in order to set up our multi-lingual site.

For products in Hikashop, the German Tab is displaying correctly, however Japanese did not appear, even though it is an installed language.

Thanks Nicolas! That did it.
