Baseball and softball topped the shortlist of sports competing for a spots as additional attractions at the Tokyo 2020 Summer Olympics along with homegrown favourite karate, organisers said on Monday.
Bowling, roller sports, sport climbing, squash, surfing and wushu were also included among the final eight, whittled down by a committee from the original 26 sports which applied for inclusion earlier this month.
As part of reforms initiated by International Olympic Committee (IOC) president Thomas Bach last year, Games hosts have the chance to bring in one or more sports popular in their country to boost ratings and attract greater sponsorship.
"The additional events will serve as a driving force to promote the Olympic movement and its values, with a focus on youth appeal," organisers said in a statement.
Organisers had previously said they would also prefer sports that are already popular in Japan so new venues would not need to be built and add to already ballooning costs.
Baseball and softball, united under the World Baseball Softball Confederation (WBSC), are strong favourites to return to the Olympics for the first time since Asia last hosted the Summer Games, in Beijing in 2008.
"This is a great day for our sport," WBSC president Riccardo Fraccari said in a statement.
"Today baseball and softball -- and the millions of athletes and fans who call it their sport -- reached first base."
Karate has never been contested at the Olympics. Judo, its fellow homegrown martial art, first joined in 1964, when Tokyo last hosted the Summer Games, and has been included on every programme since 1972.
Squash officials, who have been snubbed three-times in their bid for inclusion at the 2012 Games in London, next year's Olympics in Rio de Janeiro and Tokyo 2020, are delighted to have another opportunity.
"We are confident that squash would bring something special to the programme of the Olympic Games," World Squash Federation president Narayana Ramachandran said.
"Squash is a fine gladiatorial sport played all over the world and featuring great athleticism, competition and broadcast output."
Shortlisted sports federations will now make presentations to Tokyo 2020 organisers, with a decision on which sports will be presented to the International Olympic Committee due at the end of September. A final decision will come in August 2016.
Other sports bidding to take part had included tug of war, bridge, chess, sumo wrestling, billiards and orienteering.
