Tokyo's benchmark stock index ended Tuesday on a 3-decade high after a long weekend in Japan. And it was drug and semiconductor companies leading the charge.
The benchmark Nikkei Average ended at 28,164, up nearly one-tenth of a percent from Friday's close. That's the highest level since August 1990.
Semiconductor shares rose as investors predicted stronger demand for chips.
Pharmaceuticals also pushed the index up after reports of another effective COVID-19 treatment.
The Nikkei 225 added more than 4 percent and extended its winning streak to 3 days.
But some investors were worried by news that parts of western Japan may soon be under a state of emergency.
