The Japanese government's digital agency apologized on Tuesday for shortcomings in a new COVID-19 vaccine passport application that drew criticism from opposition lawmakers and online users for its inability to handle maiden names.

The smartphone app, downloaded more than 250,000 times since its launch on Monday by Japan's Digital Agency, works only for those who have received the so-called MyNumber identity cards held by about 40% of the population.
But it proved unable to upload data from those using a maiden name or an alias, prompting the apology in a Twitter posting by the agency, which promised to fix the issue in the "near future."
The vaccine passport app is part of Japan's plan to re-open the economy and resume travel amid concerns of a rebound in coronavirus infections and new variants.
Social media users complained about the late debut of the app, and the inability to cope with maiden names revived a long-simmering debate about Japanese laws against married women retaining their last names after marrying.
