You'd have to modify the date format in the APA style to change it, in particular add
<locale xml:lang="ja-JP">
<date form="numeric">
<date-part name="year"/>
<date-part name="month" form="numeric" suffix="月"/>
<date-part name="day" suffix="日"/>
</date>
</locale>
to the other locales towards the top of the style. See
