Lightroom completely ignores the Microsoft IME for Japanese typing on a qwerty-keyboard.
Normally one should be able to type in hiragana or katakana by typing in the characters as if romanized. The IME then converts them to kanas in automatically and suggests kanji. That's how in works in every application... Except Lightroom.
In Lightroom, you can only ever enter alphabetic characters on a qwerty-keyboard. It doesn't seem possible to enter hiragana at all, with the Japanese IME enabled, active and working beautifully in every other application.
First, I'd like to know why Lightroom ignores the IME.
Secondly, please fix this VERY soon. This is a real crapjob for Japanese customers. And whomever incidentally has to enter some japanese text into their descriptions, such as myself.
Tested on Lightroom 6.7 on Windows 10. UK English display language, UK English locale, Japanese IME on a Lenovo T450s laptop with US keyboard layout.
