Thai tourists took advantage of a weaker yen and relaxed visa restrictions to flock to Japan over the three-day Songkran holiday ending Wednesday, but a temporary freeze on Thai flight increases to the country was likely to impact numbers.

Japan's popularity among Thais as a holiday destination has skyrocketed since the government waived tourist visa requirements for Thailand in 2013, with traffic spiking in April during Songkran, the Thai New Year holiday.

According to the Japan National Tourism Organization, 657,570 Thai nationals traveled to Japan in 2014, up 45 percent from the previous year.
