An annual summer event for beetle viewing that is popular with families and children will kick off later this month at a commercial complex around Tokyo Skytree, the world's tallest broadcasting tower, in the capital.

During the event from July 20 to Sept. 1, visitors will be able to observe close-up and touch over 300 beetles released in a space designed to simulate a forest environment, according to the organizer.

From August, a further 50 to 100 stag beetles will be added to the exhibition at Space 634 on the fifth floor of the Tokyo Solamachi commercial complex, it said.

With Tokyo due to host the Olympic and Paralympic Games next year, this year's event also introduces "champion" insects, such as the best jumper and the fastest swimmer.

Visitors can also learn about edible insects and insect dishes on Friday nights, the organizer said.
