The importance to know the culture of your own country

I was asked to teach sushi making by American friends 3 years ago.
At that time, I said “I don’t know how to make sushi.”
Then, he said “Are you really a Japanese?”
I realized it’s important to know the culture of my own country so I decided to learn sushi making.
This is the beginning of Tokyo Sushi-making Tour.
Do you know a lot about the culture of your own country?

実は、これがTokyo Sushi-making Tourの原点だったりするんですね。きっかけっていうのはどんなタイミングで現れるか分からないものですね。
