We're actually creating new unique and diverse cultures by adopting and remixing parts of the various cultures we encounter. Just looking at photos from other cultures (as you have done today) is a part of that process. This is a good thing. Some of my favorite things are different takes on a thing that came from another culture. Diversity really does make us stronger and it makes our lives richer. While it might be neat to see what results from cultures being totally isolated, I think it'd be much more interesting to see what results from bringing those cultures together.
The truth is that none of those "unique and diverse cultures" you're mourning the loss of came from anything different. Even japan's culture, although it was one of the more isolationist nations, was still massively influenced by other people/places. Technology accelerates the process, but the process itself is unchanged. It made 19th century japan what it was then, just like it made japan what it is now. It's just what humans do and always have done. There's no reason to feel sad about it.
To be fair though, these photos are breathtaking. Pre-industrial era Japan is a place I'd love to visit and the history of this transformation is steeped in fear, modernizing in response to Western powers (look up Matthew Perry—naval officer, not the actor lol).
It hasn't changed much; in theory everyone has a camera in their pocket now to record the mundane, but in practice a lot of it is "content", where people put on a show for the camera.
My grandpa was an amateur photographer, he'd go out and make photos of local events, scenes, people, etc. His work has been donated to a regional museum and digitized, because there was little other visual records of these old (well, 50's) traditions.
I can't find them though. Some were uploaded to a Facebook page but that's a really poor platform for archiving / displaying works. I should reach out to my dad and start a project to build a website for this collection or something like that.
The alternative is a sort of re-enactment/cosplay approach where people consciously try to keep local traditions and minority languages (e.g. Gaelic, Sami) alive.
How you do that without being outright racist is the tough part.
And I say this as a migrated child of migrants.
But is that a good thing?
And if it is, should we be trying to promote it elsewhere where immigrant imposition does occur? And how?!
A big aspect of authenticity is uniqueness and modern culture and political thought are absolutely counter-aligned to this idea.
Poor people were not hidden away, it's just their lives weren't that beautiful to be shown and paraded around.
But over the years I have come to realise that I'm very odd.
When you go on holiday, how many photos do you take of regular people, vs. tourist attractions? Or, in reverse, do you know regular people[1] who often find tourists visiting their area like to take photos of their homes?
[0] When I visited Nairobi a decade back, one of my photos was along the lines of this Google Street View image: https://www.google.com/maps/@-1.2811367,36.9148575,3a,75y,17...
[1] This site being what it is, there's a decent chance you know someone world-famous and people do actually want photos of their home. They're not "regular people".
What does "defend" mean?
> against immigrants imposing their cultures
How can a minority "impose" its culture?
> How you do that without being outright racist
You can start by not saying "defending" and "imposing". There's no attack. "Defending" only means enjoying and promoting all the elements of your existing culture - language, music, entertainment, food, dress, architecture, religious and other traditional celebrations.
Immigrants like to be part of the mainstream so most of them will participate, unless made to feel unwelcome, usually bringing some of their own food to the party (always a plus).
And it used to be partially done by empires, wiping out local traditions. And powerful warlords would do it, too. Monarchs, etc. Hard to say Western Europe doesn't look the way it does in large part because of this multicontinental, millennia-old institution called the Catholic Church!
He'd import culture from other places he was stationed. He adopted the German custom of an after-lunch nap, which I still do.
The same during the Korean War he was a pilot in.
It isn't like we don't have records of ordinary people, even the homeless, or criminals. It's more like people like you claim the existence of a whole another kind of "poor people", who were supposedly the absolute majority, who suffered somewhere, completely ignored by everybody, and worked long hours every day on... being poor? It just doesn't seem to add up.
> What does "defend" mean?
Keep it from being replaced by another culture. I think we all understand that.
> How can a minority "impose" its culture?
By being locally dominant. By catering to people from their own community who prefer not to join the local culture. By providing cheaper/better/more profitable things to the locals than the local culture does.
For that matter, how did those coffee shops displace tea rooms?
