Toward the second stage at B factory

Abstract

The measurement and precision at B physics experiment are reviewed by taking into account of the numbers of B mesons to be produced in the future experimental projects. With $10^9$ or more B mesons we will be able to fix the parameters in Kobayashi-Maskawa matrix elements or find a signal of new physics.
