Following the deal, Pocket Concierge will carry on providing services to its current customers and restaurant partners for some time.

Pocket Concierge founder and CEO Kei Tokado said: “Pocket Concierge is a service which was created on the back of the passion and inspiration I received while working as a chef, paired with the experience of my childhood around my family’s restaurant.

Venture capital firm 500 Startups Japan made its first investments in Pocket Concierge after its launch.

In the past five years, tourists to Japan have increased from under ten million to more than 30 million, according to James Riney, the head of 500 Startups Japan.
