First, allow me entertain you with some context: https://np.reddit.com/r/japannews/comments/1atis9u/japan_drops_to_26th_globally_in_annual_pay_for_it/kqy29kl/?context=10000

It will never happen unless japan finds huge natural resources of gas/petroleum. Or anything that directly contributes to the national wealth.

Once the currency depreciates, there's no turning back. 150 yen becomes the new 110 yen.

As someone half Turkish, I'm familiar with this topic.

All Turkish people love to go to the econometrics hell and back, I see. I love my Turkish friends, as well as my colleagues in my econ department, but I don't think my friends outside of the department studied econ.

The government benefits from deliberate currency weakening, allowing market-driven price increases without criticism

Depends on the situation, and right now one of the headlines is being unable to afford certain imports e.g. 'why import if there are no buyers?'

boosting tourism and exports

True, except Japanese government restricted travels in 2022

reducing foreign debt

Such debt contracts typically include inflationary currency exchange rate variations

For instance, the Turkish government intentionally weakens the lira to cut high-tech labor costs, lower foreign debt (31.1% compared to the EU's 117.4% of nominal GDP in 2022), and enhance tourism (tourist numbers grew from 9.6 million in 2016 to 50 million in 2023).

Well, this is the first time I hear someone supportive of Turkish econ policies. I don't think they're doing themselves much of a favour though.

The reason why the USD/JPY or EUR/JPY exchange rate is the way it is now is partially due to the central banks' interest rates. The US Fed and the ECB recently peaked interest rates, while Bank of Japan has had -0,01% for some years now.
