The growth is perfectly timed to help Klook carve out an even bigger niche in the Japanese tourist market in advance of the 2020 Summer Olympics in Tokyo, where an estimated 40 million smartphone-wielding visitors will descend upon the city hungry for tours and fun.

Like with almost every other market, mobile-first companies are taking over the travel industry. Tourists booked so many tours and travel activities via their mobile devices that in 2018 trip bookings on mobile devices tripled. Bookings on mobile devices accounted for more than 75% of total bookings, according to Klook.
