Taxes and social security in J-land are a bit complicated: budget on 25% for the first year and for about 33% for the following years (residence tax and some other payments kick in 2nd year). Salaries are pretty much unchanged since pre-covid, but it's around 135 yen for a dollar at the moment as opposed to 105 yen back in 2019. VAT has increased too, inflation is knocking on the door. Not competitive anymore.
