But even the judogis "made in Japan" ain't cheap. Pakistani products, however...
"by the weaker yen"
Not sure whether particularly relevant. The terminally debt-laden economy, natural catastrophes, radioactivity scares, rumors of conflict with The Former Colonies of China, Abenomics, and sundry other catastrophes are wont to depress the yen and thus foster "exports on the cheap". On the other hand, Japan is a resource-poor country, so either they are manufacutring abroad anyway or need to import relatively more expensive materials to be assembled locally in the first place.
So I don't see how the yen exchange rate helps in the non-service IT sector.
