Windows 10: Japanese IME input buggy?

I use Japanese input a lot and it's always been somewhat buggy in my opinion.Often times when I switch to Japanese from English, it defaults to Half-width alphanumeric mode instead of my preferred Hiragana mode. So I'm constantly having to switch back and forth.Often times when I'm in MS Edge, the Japanese language will act strangely in that it will "finalize" my individual inputs before I have time to type in the next character/letter to complete a two-character/letter hiragana.If I do it quickly, I can get ta, but if I type normally or pause, I'll get t t+individual "a".This goes furt

Japanese IME disable alphanumeric input

Sorry if this is in the wrong section. I have not been here in like almost 5 years now.

I have the IME setup such that I can switch from English to Japanese with a keyboard shortcut, but there is one major annoyance: alphanumeric input is always on until I switch it with clicking the toolbar, which defeats the convenience of using the keyboard shortcut. Is there any way to disable the alphanumeric input in the Japanese IME mode? It is literally useless since I can just instantly switch between the two modes.

 

IME Japanese input

So, set up Japanese as my second input. Each time I hit alt + shift, it will switch to Japanese. However the annoying issue I am dealing with is when it switches to Japanese mode, it is in alphanumeric not hirigana mode, which is extremely annoying because
if someone switches to Japanese mode, of course, they want to start typing in Japanese, not English, so to switch to hirigana I have to hit CTL + CAPS LOCK, which is annoying to have to do two keyboard shortcuts, why can't I have it default in hirigana mode
when I hit alt + shift, instead of alphanumeric?? Is there a way to make hirigana the default option when switching to Japanese IME? Let me know thanks.

 

Can't switch input methods for Japanese Microsoft IME

Not to be obtuse, but do you know Windows 10? This person is talking about the Windows 10 IME for Japanese, the one that gets installed when you add Japanese as input language. I have the same problem: alt-shift toggles between languages just fine, but by
default the Japanese IME lets you type in latin characters ("romaji") and while we SHOULD be able to switch that input mode to hiragana, katakana, or even direct input, those options do not work. Even using the mouse to click the "A" and then selecting "hiragana"
(written in Japanese for whatever reason all of a sudden, it used to be in English unless you were running in full Japanese locale mode) does _nothing_

So: how do we fix that? What do we do in order to get the Microsoft Japanese IME to change input modes (not input languages) when Japanese is active?
