For some SE Asian scripts oblique and slanted fonts would be a separate
font family rather than an oblique style of a font family.

Don't know either, but a page[1] says:

  Hebrew doesn't have them. But people want and would use them.
  It is not true that "italics that are leaning right is acceptable". Left
  leaning italics are actually preferable.

The first sentence applies to Japanese too; professionals think "Japanese
doesn't have Italics," but people want and actually use them. We can't find
the right answer from the history but need to invent the most appropriate
answer.
