Welcome to BIGCONC

What is

I want to spread the sport "soft tennis" that originated in Japan to the world. I want to develop it into Olympic sports and professional sports like other sports that are revitalized. Why are there so few professional players in the soft tennis world after playing soft tennis for many years? Isn't it originated in global sports? Even if you win the big title of winning the national tournament, why is the way of employment becoming the mainstream in general companies? It's strange and can't be helped. Soft tennis is a great sport. We received a lot of happiness from soft tennis, and as we grew up, we also had the experience of feeling hope and potential for the future. That is why I want many people to know this charm. I want to convey and revitalize this wonderful sport that started in Japan to the world. With that in mind, we established "BIGCONC" as a society to promote soft tennis. This has the meaning of "creating a big (BIG) connection (CONCLUSION) and spreading it to the world." From now on, we will take the initiative in various efforts to spread soft tennis to the world. Would you like to learn about soft tennis together, enjoy it, and spread it to the world?

BIG CONC takes on the BIG challenge of "spreading soft tennis to the world."

What is soft tennis?

Introducing the soft tennis competition promoted by BIGCONC.




Soft tennis is a sport that was born in 1897. It is a sport that uses rubber balls to hit the ball against the opponent across the net and compete for points. Since doubles in pairs are the mainstream, mutual combination and communication are the keys to victory. Therefore, you can learn the importance of compassion for the pair and existence. In addition, team competitions, which are the total war of each team, are also held. From soft tennis, which is an individual sport and a group sport, we will improve not only technology but also mentality and humanity.

Introducing BIGCONC's activity policy




 出場者が、2度目に負けるまで優勝のチャンスがある敗者復活戦トーナメント方式です。決勝戦は一度も負けていないプレイヤー(WINNER SIDE)と敗者復活戦から勝ち上がったプレイヤー(RIVENGE SIDE)の対戦となります。この時一度も負けていないプレイヤーが勝てばそのまま優勝となります。仮に負けた場合には、もう一度同じ対戦をする『プレーオフ』を実施し、その勝者が優勝となります。

​ この方式を採用する意図は次の通りです。





Beauty Education


 "Beauty education" is an education that fosters a rich humanity through the appreciation, creation and experience of beauty . By incorporating "beauty education" into physical education and morals already in Japanese education, you can create an opportunity to develop your mental and physical skills while learning soft tennis. At BIGCONC, we aim to develop human resources who can learn the beauty of Japan and play an active role overseas by holding not only soft tennis classes but also classes in various genres.
Mind and body by picking up garbage
And the place is also "beautiful"
After Japan's defeat at the 2018 World Cup Soccer, many foreigners praised the supporters for picking up trash while shedding the same regrets and tears as the players. Not only will the audience seats be beautiful, but the appearance of picking them up will also be beautiful. By becoming beautiful in your daily life, you can give back to yourself and the people around you. BIGCONC will take the initiative in increasing the number of beautiful human resources through soft tennis. In order to make Japan and the world beautiful, why not make it beautiful from our actions and appearance?
