Blame tourist for all your countries problems
Refuse tourist into many Izakayas for decades
Fail to capture the tourist market for decades
Prices rise and force out much of the native population
Try to pivot to the same tourist you told to GTFO and never marketed to
???
FORECLOSURE!
Literal pottery.
Not a smart marketing decision to gatekeep Izakayas from people with money. Many tourist out earn even the most skilled of salarymen by a wide margin. Not marketing to this group has been a massive mistake, foolish.
The OP’s text is pretty close to how Tourism is killing all sorts of Mom & Pop businesses in Lisbon as its impact (mainly via the transformation of residential housing into AirBnBs) is pushing out the local businesses that cater for residents.
This means businesses like little grocery stores, taverns, hairdressers, even cobblers.
Now, if one takes the viewpoint that Tourists are more important than anybody else, then it’s all the fault of the small mom & pop grocery stores, taverns, hairdresses and cobbler for not having proper strategies to market themselves to tourists or at least not pivoting their businesses to sell more knick-knacks to tourists.
An alternative view is that Tourism has negative externalities (its version of “polution”) and has to be controlled so that it doesn’t destroy the very ambience that attracts tourists (in my example that would be things like the Traditional Lisbon neighbourhoods).
If indeed Tourism in Japan is pushing out the locals who frequented Izakayas be it directly (because those people don’t live there anymore) or indirectly (realestate prices going up because of Tourism, making everything more expensive including Izakayas), then this is a problem with Tourism rather than the Izakayas.
If that is not the case, then there is some other problem in Japan (maybe a falling real purchasing power or the slow change of habits as newer generation replace the older ones), in which case that’s unrelated to Tourism. Maybe Tourists could make up for it, but what I can tell you from my experience in growing up in a place which over my lifetime was “discovered” and became very touristic (and then incompetent politicians thought it was a silver bullet to the country’s problems and went full blown insane on it by which point all the negative externalities of Tourism really started to hurt, especially the realestate bubble), traditional business which morph to cater to tourists tend to become over time a bland parody of the local traditions rather than the real deal, plus a lot of supposedly “traditional” businesses popping-up to cater for tourists are a lot more like the versions you would find in an airport than the real traditional thing. Certainly the restauration business in Lisbon which cater to tourists are a lot more like the cookie cutter glitzy but bland continental food restaurants serving “universal food” you see in airports all over the World than the traditional restaurants in Portugal.
I live near a big city. I like tourism for the city because it has the infrastructure to handle it. Some tourists come farther out and that is fine but you don’t want the same numbers as downtown go to some smaller town in the vinicity because it simply does not have that level of infrastructure. Also organized things are easier like concerts or such.
