Chief Cabinet Secretary Yoshihide Suga told reporters in a routine briefing on Wednesday that the ruling party and its coalition partner the Komeito were still hammering out details of the plan. Japan's economy, the world's third largest, has stagnated for years, and massive monetary and government stimulus have so far failed to jolt it into a sustained recovery. [...] the aging and shrinking of the Japanese population has discouraged companies from investing much in the home market, and wages have not risen significantly enough to drive a spending boom, despite a very tight labor market.
