The 30,000-seater facility, which opened in 1978 and is the home of Japanese Central League side the Yokohama DeNA BayStars, could host matches at the Games in four years’ time.

A joint bid from men's baseball and women's softball is one of five new sports set to be added to sport's biggest stage, along with karate, skateboarding, sport climbing and surfing, subject to approval at the International Olympic Committee (IOC) Session in Rio de Janeiro.

The WBSC has denied reports that the facility in Yokohama is their preferred option, who are keen to cement plans for where baseball and softball games will take place if they get the green light from the IOC as expected.

insidethegames understands the WBSC are due to have meetings with Tokyo 2020 in the next few weeks, with venues expected to be high on the agenda.

"WBSC will meet unofficially with Tokyo 2020 following their feasibility study on potential venues," a WBSC statement sent to insidethegames read.

"At this stage of the process, WBSC is fully open to reviewing any potential venue plans with Tokyo 2020 and the IOC, and WBSC already has detailed venue reports on the crown jewel Tokyo Dome, the Sapporo Dome and Iwaki Green Stadium, as well as other venues, due to our past or upcoming events. 

"In Tokyo and across Japan, there exist millions of baseball/softball fans and many world-class baseball stadiums, which are homes to clubs of our Associate Member, Nippon Professional Baseball. 

"We are looking forward to further discussing ways to apply IOC President Bach’s Agenda 2020 vision ahead of the vote in Rio."

The 55,000-capacity Tokyo Dome, a multi-purpose arena which is predominantly used by the Yomiuri Giants baseball team, and the Chiba Marine Stadium have also been considered.

The Tokyo Dome is seen as one of the most iconic venues in the country and would perhaps be the favoured choice of the Japanese public.

Kyodo News has reported that Nippon Professional Baseball, the highest-level of the sport in the nation, will look to change its season to accommodate the Olympic tournament at Tokyo 2020 should baseball and softball be formally accepted.   

Earlier this year, Tokyo 2020 Olympics Minister Toshiaki Endo claimed they may look to stage baseball and softball events in disaster-hit Fukushima.

Endo met with IOC President Thomas Bach to discuss the idea.

The region was struck by one of the worst natural disasters to ever hit the country in 2011 when a devastating earthquake and tsunami caused a nuclear accident at the Fukushima Daiichi Nuclear Power Plant.

A total of around 16,000 people lost their lives in the disaster.

The damage caused by the tsunami produced equipment failures and as a result, three nuclear meltdowns occurred, prompting the release of radioactive materials.

It is considered the largest nuclear incident since the Chernobyl disaster in 1986.
