Klook is adding a further US$225 million to its Series D round, bringing the total raised in this round to US$425 million.
The D+ funding is led by Tokyo-based SoftBank Vision Fund, while existing investors Sequoia China, Matrix Partners, TCV and OurCrowd also participated.
The tours and activities segment has received huge investor attention recently, but this investment is the largest funding to date by some distance.
According to a statement, Klook plans to bring its service to new geographies as well as continue expansion in existing Asian markets.
It highlights Japan as one of its “most important markets,” saying it plans to “deepen its investments ahead of the 2020 Summer Olympics in Tokyo.”
Lydia Jett, partner at SoftBank Investment Advisers, says:
“We believe Klook is a leader in taking a mobile-first approach to the travel activities and services industry.
“The company has seen great success in scaling its business across different geographies and cultures, and we are excited to help them drive further innovation in the global travel industry.”
Klook, which was launched in Hong Kong in 2014, has raised to over US$520 million across four rounds.
In its initial announcement of the Series D round last August, the company said it was eyeing Europe and the US for expansion.
Earlier this year, it announced a partnership with RailEurope for Klook users to access European rail products while customers of the rail distribution service can buy tours and activities products.
