My own experience has been that the average quality, and especially the like floor of the quality of food here in Japan is pretty high compared to Australia. What you get compared to what you pay for is especially high in Japan’s favour. But perhaps you’re right that the hype is not deserved, if you’re coming here expecting a heavenly experience then you’re probably going to be disappointed purely because of unrealistic expectations. I would say tourists from wealthy western countries should expect decent food for a great price. Touristic places might have higher prices though.
