I fear I have no expertise with a Japanese keyboard layout. I do understand that typingb in a language (e.g. English) in a keyboard made for, or using a different locale (e.g. Japan) will couse headaches.
So, it is good you asked this question as I realise my answer above isn’t in aTbRef but really ought to be. I ewas gpoing to point you as a reference in aTbRef only to find the information wasn’t there. 
I’ll address that.
Meanwhile:
- setting the OS setting may help in your case, e.g. in your more-than-one-language/locale scenario, but I don’t think it applies to everyone (thinking of other readers of this thread)
- if in doubt, check the Unicode values of your quote characters. The OK ones are as listed above.
