More than half of municipalities in Tokyo and neighboring prefectures will disclose the names of missing people in a disaster despite concerns about personal information protection, a Kyodo News survey showed Saturday.

Ahead of Disaster Prevention Day on Sunday, the survey was conducted in July and August with all 212 municipalities in Tokyo and the prefectures of Saitama, Chiba and Kanagawa, with a response rate of 100 percent.

Some 56.1 percent of the respondents in and around the area said they will disclose the names of people unaccounted for, or do so if conditions permit, according to the survey.
