Introduction

Japan is no longer only a story about deflation.

For decades, Japanese data were read through one question: could the economy escape low inflation and weak wage growth? That question has changed. The new question is whether Japan can sustain a wage-price cycle strong enough to support policy normalisation.

The central question is:

Can Japan move from deflation management to normal monetary policy without damaging consumption, the yen or the government bond market?

Three data groups matter most.

Wages show whether inflation can become domestically sustained. Consumption shows whether households are gaining real purchasing power. The yen and Japanese government bond market show whether policy normalisation is orderly.

For Japan, data analysis is ultimately about transition.
