1. Borrow Yen at 2% at IB.
2. Purchase a basket of J-REITs (Japanese Real Estate Investment Trusts) at single digit P/Es, 40% of book value, and double digit dividend yields
3. ???
4. Profit!
When something is cheap it is almost always cheap for a good reason. The trick in long term investing is to find things that are too cheap, with a price that is irrationally low, and buy them.
Inflation is a bull factor for REITs. Their debts stay in nominal money, whilst rents increase in line with wage/price inflation and capital values follow suit.
A typical REIT that has say 50% borrowings, if the CPI doubles then its borrowings stay at 50 whilst its assets double in price. The yield would go from 10% to 20%, the asset value from 100 to 200, the debt would stay at 50. Thus, equity would triple, for a doubling in inflation.
REITs are an good inflation hedge. It is disinflation and deflation that is the real danger for real estate - the exact opposite of what you say.
Besides, inflation is not exactly soaring in Japan. Due to their persistent deflation problem, an emergence of inflation would actually be a *bull* factor for the economy and markets (except govt bonds).
