japanese ui is often more dense and information rich. there are left to right and right to left cultures. tonnes of difference between cultures and understand of the world.
On the one hand, there are people who deeply understand the technical intricacies of Unicode BiDi yet can’t actually read Arabic or Hebrew
On the other hand, if the business doesn’t view Arabic markets (or Israel) as viable to pursue, it doesn’t matter how much you are aware of those languages, it is irrelevant to the product
And what about backend developer roles, where UI concerns like BiDi are largely a non-issue?
