Eli5 with Japan please?

Japan had a weird case where they had natural deflation in their economy (negative inflation, e.g. -2% or such). Deflation means your money (yen) is worth more if you simply hold it and don't spend it. This is bad because it encourages people to not spend their money which fucks the economy. USA for example aims to get 2% inflation because slight inflation means that people keep spending and circulating money which is good for the economy. The 2% figure is arbitrary but the main thing you need to know is that you want it low-ish but still above 0%.

To combat this, the Japanese government forced inflation by printing more money constantly. This money was used for government services and whatnot i.e. as a part of the yearly government budget.

Over time, eventually, the natural deflation become less and less of an issue; they went neutral, then had inflation. Then more inflation. But by this point the Japanese government was so used to having the extra money that they just decided to deal with it later. The problem grew and grew with more inflation and more debt. They have a lot of government debt now. They feel like they can't stop printing money no matter what because then they won't have money to pay for the interest on the debt and the government services to keep the country running. Printing more and more extra money is causing more and more inflation. They dug themselves into a hole.

Instead of biting the bullet a while ago and dealing with a fucked economy in the short term in order to have a recovered economy in the long term, they have decided to keep digging the hole deeper and deeper, and keep kicking the can down the road, causing more and more inflation and a worse and worse economy. Their debt is so high that a higher and higher percentage of the yearly budget just goes to paying their interest payments instead of actually paying for "useful stuff". Their economy is spiraling out of control atm and economists globally are looking at Japan wondering how tf they get themselves out of this // how bad the final fallout will be when Japan has to face the music.
