ASB scenario - Japan ISOT'ed 100 years in the past right after Hiroshima detonation

What if immediately after the Hiroshima detonation of August 6th, 1945, Japan, including all its people and all objects and waters within its 12 nautical mile limit into the ocean, and encompassing the Homelands, the Kurils, southern Sakhhalkin, the Bonins north of American-captured Iwo Jima, and the Ryukyus north of American captured Okinawa, is sent back in time to August 6th, 1845. None of the other Japanese overseas territories or protectorates or occupied territories like Korea, Taiwan, Manchukuo, occupied China or Indonesia are coming with them, north the military forces there, north the Japanese civilians and officials abroad.

Japan is now in the mid-19th century, with no one trying to invade it, just curious westerners trying to trade with it. It is heavily burnt, damaged, and food insecure, with possibly a female-skewed gender ratio. It's inland waters are mined. But at least the Japanese soon find the sky won't be raining bombs. Although back on it's here's, with damaged infrastructure and urban housing stock and low fuel supplies, it's people possess the most state of the art technical knowledge and weapons in 1845.

One of the first things the Japanese notice, in addition to the end to the bombing, submarine attacks, and shore bombardments, is the sudden absence of anyone's radio traffic but their own. And furthermore, the absence Japanese overseas radio traffic.

How will Japan go about surviving, rebuilding, prospering, and reshaping the new neighborhood and world it finds itself in?

....meanwhile...

In a dimension of the multi-verse next door, where all this Japanese territory vanished in an instant on 6 August, life goes for the world of 1945, but those Japanese lands are replaced by their equivalent lands from 6 August 1845.

Later on August 6th, Americans notice the sudden 'radio silence' of the Japanese home islands, which is inexplicable.

American reconnaissance flights overfly to inspect damage and look for further targets. Their reports are uniformly...strange.

Their finding nary a factory, a ship, an airfield or metal weapon.

Close-flyboys show fields and urban masses, with pilots and navigators saying the landscape "doesn't look built up, it doesn't look knocked down, it just looks...pretty as a picture"

How do the Americans, and the world community, deal with a Japan 100 years behind, not actually responsible for the late war, and war crimes, yet which they want to never become a warlike state, and is the only place to deposit a over million Japanese overseas (overwhelmingly servicemen) from the 20th century who need to be repatriated from countries the Japanese empire conquered and occupied during the late war or even earlier?

Hmm well the Japanese who are sent back in time, after they recover the smart thing for them to do is to break the United States so that it never rises as a super power and threatens them.

Potentially as bad as your other scenario, especially since Japan is more isolated here with no great powers nearby to check any recovery once it gets back on its feet.

In the 1945 world hopefully the US will realise what's happened fairly quickly and stop the bombing as well as make the following occupation less bloody than it might otherwise be. Could be a complication if Stalin tries occupying parts of the Japanese main islands as well as the Kurils and S Sakhalin.

One other complication is that there's now no emperor, or at least one they recognise to prompt the surrender of the Japanese forces outside the affected areas. As such they likely to have to be taken down the old way, which is probably going to mean several months at least further fighting and Korea at least is going to be united under communist rule.

To be honest the smart thing to do with 1845 Japan is to leave them alone like we do the Sengalese Islands. Let the Japanese maintain Sakkoku and stay in the medieval period without the outside world interfering. After all if the U.S. did not fuck things up by wanting to open Japan to the outside world in the 1800's then Japan would never have become a problem in the 1930's and 40's.

You mean the Sentinel Islands?

I could see a fun argument for keeping it isolated and treating it with the Star Trek "prime directive".

But I would also ask where else would you put all the modern Japanese PoWs and civilian repatriates at the end of the war?

Of course, you may have limits a high percentage of Japanese forces overseas fight to the death which will reduce PoW #s. This causes its own problems, as Stevep noted:

I suppose the Soviets are cool with holding on to captured Japanese PoWs and civilians in the northern isles, Manchuria, and Japan as lifelong slave labor. Unless the Americans jump onto the mainland with both feet in support of the Chinese Nationalists, the Soviets will also be in the better position to keep on overrunning Japanese forces in northern and eastern China in the remaining months of 1945.

Japanese in areas further south will be the responsibility, generally, of the western allies and local resistance forces. Is Okinawa big enough to host all the survivors of this "cleaning out" process plus the Japanese of Micronesia and Taiwan?

Indeed.They could take send small force on small ship to help Mexicans in 1845 - it would be enough to stop USA.Then take Malaya and Dutch india/oil and rubber/ and wait one generation without scharing technology.
After 1865 go conqest Pacyfic schore of USA and Canada.Take Siberia from tsar.Take Australia/coal and gold/ And it would be enough - Japan do not wonted bigger empire.
Taiwan and Manchuria,too.

1845 Japan - soviets would try conqer them.Sachalin is lost,but USA could hold Kuriles and Japan islands against them.
Best scenario - keep shogun.Do not made any changes.
made Ryukus island independent again.
But,american being american,they would try made all there good democrats.
