Tokyo bus tour operator Hato Bus Co. celebrated its 70th anniversary Tuesday, with its unique jaunts around the capital continuing to attract many visitors from around the country and also from overseas.

Known for its bright yellow buses marked with its logo of a dove, or hato in Japanese, the company has long offered a variety of routes, ranging from conventional tours of famous tourist spots, including Tokyo Tower and the Asakusa area, to a more quirky night tour of Japanese bars with male companions, known as host clubs, in the Shinjuku area.

The Tokyo sightseeing tours have so far attracted more than 50 million people.
