Japan is extremely different from the US. If you're looking for "the 4% rule can be applied safely to all things forever," the answer is of course not. To your situation? The answer is probably.
However, Japan is not particularly welcoming of immigrants, who are a huge source of energy in the US economy.
Japan is having very few children. The US still isn't even sure how it feels about the birth control it invented.
Japan's territory and natural resources are finite and may be more finite with climate change. The US is in a better position and has much more land.
Japan's culture has become very pro-saving. The US obviously doesn't have this feature.
Japan's culture is not pro-invention. They tend to perfect goods and processes that others invented, but their ability to do that cheaply was weakened as they reaped the rewards and raised standards of living. Inventors, however, often are so averse to receiving credit that they lie about it entirely or try to get others to claim inventions for them when faced with the press. Meanwhile, the US has Kanye, who hasn't invented anything, and wants credit for all the things. We also have Google, Amazon, Facebook, Microsoft, IBM...
Japan has housing rules that actually make it cost-effective to let a house rot than to do anything with the space it occupies (a loophole not understood when they first made development incentives that greatly favor "a thing built on a spot" vs "an open spot," which has exacerbated urban blight and housing values.
Inventors' capacity to create wealth is also not an immediate export requirement - your new and old inventions can make money all over the place. Frozen potato flakes are still pretty respected in places like Nigeria for preventing waste, and they're "newer," so to speak. Elsewhere, like Algeria, technology might be upgraded overnight with new cellphones, skipping the landline step entirely. An awful lot of global development helps American companies. I love to point out to people complaining about apple pickers sending money home at $2 an hour and "draining" the economy that the Wal Mart in Argentina is sending a lot more back.
