Emergency kits are a must-have in earthquake prone Japan, but a survey by The Japan Times has found that a number of people did not use theirs when a deadly quake rocked Osaka Prefecture and its vicinity last week.

The June 18 quake, which affected 30 percent of the approximately 250 people who provided valid responses to the online questionnaire conducted in its wake, prompted many to re-examine their preparations amid fears of a possible follow-on temblor, it found.

And while 42 percent of respondents said they have emergency kits both at home and at work, several revealed the need to better plan for earthquakes and other disasters.
