TOKYO • Japan's Tokyo metropolitan government yesterday confirmed 67 new Covid-19 infections, the highest number of daily cases since the state of emergency was lifted on May 25.

The number, up from 54 on Tuesday, came amid growing concern over a second wave of infections in the capital of 14 million people after business and social restrictions were eased in stages, Kyodo News reported.

The figure topped 50 for the sixth straight day, taking Tokyo's cumulative total to nearly 6,300.

The Nikkei Asian Review quoted Governor Yuriko Koike as saying "most of the patients are in their 20s and 30s".

Yesterday, Tokyo Disney Resort welcomed visitors for the first time in four months, with fans practising social distancing.

Visitors in face masks queueing on floor markings clapped as the gates of the Magic Kingdom reopened, and were encouraged to clean hands, pay without cash and avoid screaming, Reuters reported.

The resort will operate at 50 per cent capacity for the foreseeable future, while parades and shows remain suspended.
