The Olympics have the power to turn obscure sports into much bigger attractions once they've been included on the program for the global sports extravaganza.

So the announcement two years ago that sport climbing — which combines bouldering, lead climbing and speed climbing — would be included on the program for the 2020 Tokyo Olympics was a good day for fans of the sport. Especially for those in Japan.

On Saturday and Sunday, the 13th Bouldering Japan Cup was held at the indoor arena of Komazawa Olympic Park. The event nearly drew a full house on the final day, with a record crowd of 1,661.
