This is a funny video but far too cherry picked to be worth much of substance. Going to Shibuya (the Las Vegas of Tokyo) and interviewing unmarried women in their 20s and 30s it's no surprise you get very skewed results. It's very important to get data from a wider age range, relationship status, and geographical distribution. Anonymity also plays a factor, as not everyone is comfortable on camera, particularly to discuss such a topic.
Actual data from studies and polls usually show that, in marriages, it's more likely for men to cheat compared to women. Lower estimates put it at around a 20% rate, while higher estimates can cross the 50% range. That big margin shows how complicated this type of data is to gather in and of itself. For married women the rate seems to hover between 10% and 30%. This is based on my own cross-referencing work between several sites and polls, but I'm still not happy with my findings and am trying to find more reliable estimates.
A lot of this data is primarily skewed by what people even view as cheating as well. For example, a lot of folks do not consider using paid sex services as cheating, whether they're men or women. There's also what counts as cheating in terms of what you do with another person, some say a kiss is cheating, some say only sex is cheating, etc. (

Though one major difference between men and women is the reason for cheating. From one poll I saw, most married women who have cheated tend to give "marriage problems" as their primary reason (poll I say put it as high as 45% of the answers), while for men the reasons are more spread out, ranging from daily stress, to marriage problems, to lack of intimacy in the bedroom, to finding someone more attractive.

Then there's actual views on is cheating okay or not.
One of the polls I found (500 people sample size) had the following data
For married men:
6.2% said cheating is completely okay
30% said cheating is okay as long as it doesn't get found out
38% said cheating is not okay, but it can't be helped that it happens
26.9% said cheating is never okay
For married women
0.8% said cheating is completely okay
9.4% said cheating is okay as long as it doesn't get found out
31.5% said cheating is not okay, but it can't be helped that it happens
58.3% said cheating is never okay.
So from this we can conclude there is a massive gap in how married men and women perceive how okay it is to cheat, and also that there is at least sizeable chunk of people who, despite condemning cheating, still view it as "it is what it is."
There's also data distinction between unmarried and married men/women but for the purposes of this story I was trying to focus primarily on married couples.
And again these are just some preliminary numbers I dug up online, it's not very deep research and I don't want to present it as such. I'll only write a tl note on it if I can have a higher degree of confidence in the data.
