Tokyo and six other prefectures entered their first weekend under a state of emergency on Saturday, with authorities strengthening calls for people to stay home and for nonessential businesses to temporarily shutter to curb the coronavirus' spread in Japan.

Areas around Shinjuku Station in Tokyo that are normally packed with shoppers appeared semi-deserted with department stores and restaurants closed for business.

"I came to the office because my work is piling up. It's the first time I've seen Shinjuku so empty on a weekend," a Shinjuku Ward office employee in her 50s said.
