An online survey by ad behemoth Dentsu Inc. says domestic travel will be the most popular way to spend this year's summer bonus for the second consecutive year.

The survey said 30 percent of 667 respondents, who were aged between 20 and 69, plan to use their bonuses on travel in Japan, up from 22.2 percent last year, when many curbed spending after the March 11 calamity. The survey was held in late May.
