Japan's government debt climbs to record ¥1.32 quadrillion
My understanding from past reading is that Japan has an unusual situation where the Japanese public basically lends the government a lot of money at fairly unfavorable-to-the-public rates.

Based on a skim of this, it sounds like a lot of the Japanese public basically lends their assets to the government, while getting fairly unrewarding returns for them.
Then the government takes those assets and goes and invests the assets in riskier things abroad and makes a bunch of money by doing so.

First, as of the second quarter of 2024, Japan’s net public liabilities on the consolidated balance sheet amounted to only 78% of GDP. While gross liabilities stood at 270% of GDP, the government also held substantial assets totaling 192% of GDP.

Second, a significant portion of these assets were invested in high-return, riskier assets such as domestic equities, foreign equities and foreign bonds. Liabilities primarily consisted of low-return instruments like bank reserves and government bonds. This resulted in a return spread between government assets and liabilities. Despite having a net liability position, the high returns on riskier assets exceeded the government’s funding costs, generating a substantial positive return on Japan’s balance sheet.
So, I don't know why the Japanese public is so willing to lend to the government at poor rates of return. Maybe cultural, maybe driven by tax law or other policy.
But from the standpoint of looking at the country in aggregate, it doesn't sound so bad. Basically, the Japanese government has a lot of public debt because it's chosen to take out debt from the public, who is willing to lwnd to it and makes a return by investing those assets. It's not because it's just spending beyond its means. High debts but also high assets and those assets have made a solid return.
There's also some other material in the article about how another part of it is due to some unusual financing structure, but I haven't read about that before, and don't have familiarity with it.
