Sumo is a very famous and historic sport in Japan, which has become a "national sport" by the Japanese, equivalent to a national sport and plays an important role in Japan. Therefore, sumo wrestlers will be well paid and have a high social status. When the Japanese people mention them, they will also have worship views.
Many Japanese born in poverty were sent by their parents to practice sumo when they were young, hoping to become famous sumo athletes one day, so as to get rid of poverty and honor their ancestors.
So it is normal for Japanese women to want to marry Japanese sumo wrestlers. Marrying sumo wrestlers is equivalent to entering a higher social class, eating, drinking and living a rich life. If you really love each other, it is the best destination for Japanese women.
What's more, sumo wrestlers have high demands on their bodies. They must be more than 1.75 meters tall and weigh more than 240 kilograms, and they can't lose weight as athletes. So sumo wrestlers are really "tall and burly", so women will feel that they are safe and willing to marry them.
