JPY negative interest rate i.e. the inflation tax!

JPY holders are now experiencing the negative real interest rate steadily depreciating our real income, sigh. 

Interest rate r_US > r_Jp. ∴ Money Demand: MD_US > MD_JP
Furthermore, I detest the current Japanese interest rate policy. Usually, the nominal interest rate  is supposed to rise to offset the price inflation rate (ΔP) to keep the real interest rate (r - ΔP: what actually influences the money value held by the savers and the national debt investors) zero at lowest to make it fair and functional. 

The severe problem of Japan is that the current real interest rate for JPY is "negative (-)" which substantially discourages the money demand as well as reduces the real income value (income value depreciated by the price inflation). This is called the inflation tax because the price inflation works as though it were the tax imposed by government allowing the central bank to issue the excess money supply causing the price inflation depreciating the income. Because the inflation rate equally affects all individuals holding JPY, this is indeed a regressive tax (taxing proportionally more to the poorer but less to the rich)!!!!!

The reason why JPY interest rate has neither been raised nor seemed to rise soon is that the Bank of Japan (BoJ) is neglecting the interest rate rise despite this inflation. Actually, the Japanese government reject raising the interest rate because it is more likely to trigger the potential bankruptcy caused by their national debt interest payment overwhelming their budget. ......... thus, JPY holders are now literally experiencing the negative real interest rate steadily depreciating their real income.

Some very rich famous people must have predicted this world economic situation since ages ago. He's accumulated physical gold ingots in his own safe. The current world situation is really dodgy! ... under such a chaotic world situation, I'm thinking of you, my dear friends. Praying for safety of you and your family.
