Why don't the Japanese believe in the documentary "The God of Sushi"?

I believe everyone has heard of the documentary "The God of Sushi". Even if you haven't seen it, you should be able to imagine what this film is about. This film tells the legendary life and efforts behind the success of Erlang Jiro Ono, the world's oldest Michelin three-star restaurant. In this movie, every step of making sushi seems almost harsh.

The learning process of sushi for several years is even more common. However, nowadays, more and more people think that what these sushi chefs claim is actually just a scam. When talking about why there are no female sushi chefs in Tokyo, Jiro Shouhiqiao, Yoshikazu Ono and his father Jirooono (the protagonist of Sushi God), he said: The reason is that women have menstrual periods. To be a professional sushi chef, your taste needs to be stable, but because of the menstrual cycle, women's taste is unstable, and women's hands are too small to handle sushi warmly. Cosmetics and perfumes will spoil the taste of meat. To put it more vividly, some people are born with a gift from heaven and have a keen sense of taste and smell.

Over the years, revolving sushi restaurants have become more and more popular in Japan, and they are also widely welcomed by Japanese foodies. Some sushi chefs call these restaurants "fake sushi".

Netizens think it is a joke that sushi chefs say it will take three years to learn how to prepare rice and eight years to learn how to put sushi into sushi rolls.
