Yen hits 162 against the dollar, anyone else concerned about the rising cost of living in Tokyo?

I remember in February or March of this year, some finance bro posted here saying that the yen would hit 180 by the end of the year and everyone laughed at him. He continued to say that the yen could hit 250 within 2-3 years…

Well, yen just hit 162 and it's only July. I know that we get paid in yen, but sliding this much against the dollar does impact us greatly since Japan is such an import intensive nation. I mean surely everyone must be feeling the inflation by now too, right? Everything is at least 10-20% more expensive AND the portions are smaller now too.

I'm seriously wondering if the move is to transfer back to America for a few years to save up some money and come back once things stabilize. But WILL things stabilize? Why is Japan getting hit so much harder than Korea or Taiwan? Japan is America's strongest ally in Asia and 4th largest GDP in the world (formerly third), doesn't make sense that the yen would hit 250 but it really seems to be going in that direction at a fast rate.
