The 46th Tokyo Motor Show slated to kick off Thursday will not just focus on futuristic, cutting-edge vehicles, such as self-driving cars, it will also shine a light on unconventional mobility devices and exhibitions for children aimed at reversing flagging attendance.

The show once enjoyed a reputation as one of the world's five biggest auto expos along with the Frankfurt, Geneva, Detroit and Paris shows. But it has recently lost its position as Asia's top venue to the Chinese expos in Shanghai, Beijing and Guangzhou.

The 46th biennial exhibition, to be held at Tokyo Big Sight convention center and its vicinity through Nov. 4, will be attended by 192 carmakers and organizations from eight countries, down from a peak of 361 in 1995, according to the Japan Automobile Manufacturers Association, the nation's largest auto lobby and the show's organizer.
