Total debt outstanding: about 1 quadrillion yen, of which 821 trillion yen consists of bonds as of March 31 (the end of the 2012 fiscal year). For those of us without Ph.D.s in large numbers, 1 quadrillion is 1 followed by 15 zeros. Budgeted bond issuance for fiscal 2013 is 170 trillion yen. A reasonable estimate would be 1.2 quadrillion yen in total debt by the end of fiscal 2013.
Total national debt service (interest payment): 22 trillion yen, or 24% of government revenue (90 trillion yen), as of fiscal 2012.
Given that the average maturity of outstanding Japanese debt is about eight years, a 1% increase in the yield of eight-year Japanese government bonds translates into 1.7 trillion yen in extra cost in new issuance for fiscal 2013, and an 8% capital loss (or 80 trillion) for bondholders, 69% of which are domestic banks, insurance companies and pension funds.
The yield on the eight-year JGB increased from a recent low of 0.305% on April 4 to 0.797% on May 28. That's a mark-to-market loss of about 40 trillion yen for bondholders in less than two months.

The increase in JGB yields has been quite furious, as you can see from the chart below. Note that the increase in the immediate aftermath of earthquake/tsunami/nuclear-meltdown disaster of March 2011 was buried in the noise in the chart.
More important than the fast rise is that this is happening after the Bank of Japan announced unprecedented qualitative and quantitative easing, as part of three-arrow Abenomics, including an estimated JGB purchases of 80 trillion-plus yen.

When the market doesn't want to front-run you, despite your public announcements over every loudspeaker in every corner of the globe, you ought to be worried.
Why doesn't the market want to front-run the Bank of Japan? There are two possible reasons:
- Inflation expectations are higher. This would be exactly what the Bank of Japan wants. Unfortunately, as Goldman Sachs research recently showed (via ZeroHedge), the inflation expectation remains mostly flat, at less than 1% out to 2016 after taking into account the planned consumption tax increase in April 2014.
- The market is worried about the risk of BoJ losing control of the yield curve. This is nonsensical at first glance: They'd just print more money and buy up JGBs. But in reality there's another limit to how much BoJ can buy: the repo market. As recently happened in the U.S., banks may run out of Treasuries as collateral if the central bank monetizes too much. This severely disrupts banking and money market operations.
Unless the Bank of Japan manages to stop the yield surge soon, a positive feedback loop may kick in and push things out of control: The major JGB holders, Japanese banks, insurance companies, and pension funds, would be hit with a triple whammy of:
- massive mark-to-market losses,
- sharply increased risk reserve requirements heavily dependent on JGB volatility, and
- collateral squeeze.
If/when forced selling starts, it would become a chain reaction.

I'm not saying this would happen soon. Systems with such great nonlinearity are extremely hard to predict and particularly difficult to time. The point is that the situation is very unstable and warrants close attention.
