> In Japan, there's a big issue when a snack raises its price 2 cents
No, there really isn't. You're looking at one company that "apologized" as a marketing play but outside of that prices have been increasing with no fanfare for years now. The annual inflation rate has been 2-3% for the past 4 years. It's a lot less interesting to write a news article about that though.
Yeah, and the price of rice has increased way more than that. Heat is making me too lazy to look it up so I wonder if it's gotten better in the past year. But Japanese people are very used to price increases.
Granted, accommodation is not one of them. Especially if you compare Tokyo to London, Paris or even Geneva.
