Using "ha" instead of "wa" with QWERTY keyboards


Why is it standard practice to use "ha" when you are translating は{wa} to
Romaji? This has always confused me. これは... is pronounced "Kore wa" but when
you write it out you write "Kore ha". Hiragana は{ha} when used as a particle
is pronounced "wa" so why do we not write "wa"?




Because computers cannot read your mind. When you type "wa", the computer
cannot decipher whether you mean わ or は, so it was decided that わ would be the
only way. You could argue that you could develop a system to perform 変換 based
on context, but I would imagine that any attempt would fail. Also, if you
don't like this system, you can always use かな入力 (mainly used by people who
don't understand ローマ字), so when you hit the は key, you will always get what
you want.
