The number of adults traveling abroad with their parents nearly doubled in five years amid a growing number of those in their 20s and 30s taking such trips to show filial piety, industry data showed Wednesday.
The number of those aged over 19 years and their parents traveling overseas together on group tours surged 91.5 percent to 274,000 last year from 143,000 in 2012, according to Hana Tour, South Korea's biggest travel agency.
Their proportion of the total number of group tourists stood at 18.6 percent last year, up from 16.6 percent in 2012.
The ratio of people traveling with children under 12 years old, meanwhile, fell to 16.5 percent last year from 19.3 percent in 2012.
The number of those in their 20s and 30s traveling with their parents has risen in recent years, while those traveling with children dropped due to the falling birthrate, a Hana Tour official said.
Japan was the most popular destination among adults traveling with their parents at 31.3 percent.
Vietnam came in second at 13.2 percent, followed by China at 8.9 percent, Thailand at 8.3 percent, Europe at 7.7 percent and Taiwan at 6.6 percent.
