Fasulo told the Olympic Channel the organisation was "satisfied with the level of conditions we experienced" at Tsurigasaki Beach during the competition, part of the "Ready Steady Tokyo" test event series for next year's Olympic Games.

The start of the event last week was delayed because of weather conditions and small waves, while organisers decided to bring the end of the competition forward by a day to avoid heavy fog.

It allowed Tokyo 2020 organisers and the ISA the opportunity to to see the venue - located 90 kilometres south-east of Tokyo - in similar conditions to the Games and test all aspects of the event, including security, medical, technology, the format, scoring, live scoring, results and sport presentation.

Concerns have been raised in the build-up to surfing's first appearance at the Olympic Games over the waves as it has been claimed between late August and October is the best time to surf in Japan.

Surfing will be held at a slightly later time at Tokyo 2020 than the test event as competition is scheduled to take place in a four-day window between July 26 and August 2.

"We had the opportunity to test a lot of different elements," Fasulo said to the Olympic Channel. 

"We're very satisfied first of all with the level of conditions we experienced here because there’s been a lot of perception that the waves and the conditions wouldn't be sufficient. 

"But we had some excellent waves and in particular the men's final.

"At the end of the day we are thinking about the best conditions for the athletes and the best way to promote and showcase the sport which is why and how we took the decision to finish today.

"For me, the biggest three lessons were that, the event format works, that the waves are absolutely up to standard to run a high quality world class event, and that we can innovate a little bit in the way we present the sport."

Hiroto Ohhara claimed the men's title, while Minami Nonaka won the women's crown at the all-Japanese event.
