Tokyo stocks soared Thursday to a three-month high on optimism over the gradual reopening of virus-hit economies worldwide, as investors also kept a close eye on US-China tensions over Hong Kong.
The benchmark Nikkei 225 index ended up 2.32 percent, or 497.08 points, at 21,916.31, while the broader Topix index was up 1.80 percent, or 27.87 points, at 1,577.34.
"Japanese shares are supported by US rallies" with traders bullish on the reopening of the US and Japan, said Toshiyuki Kanayama, senior market analyst at Monex.
Concerns, however, for a simmering row between the US and China over Hong Kong's special status are putting a brake on the euphoria, analysts said.
"A sense of overheating in the market and worries over the US-China row grew in later trade," said Daiwa Securities.
