How to make a Japanese rolled omelette ( Dashimaki Tamago )
as demonstrated by the Master Chef at the Shunraku Kaiten Sushi Restaurant, Shunraku on Route 36 Eniwa Hokkaido.

材料　Ingredients
玉子 eggs 8
砂糖 sugar 30g
塩 salt 3g
みりん Mirin 1tsp （1パイ）
酒 Sake 1 tsp　（1パイ）
カツオダシ Bonito Stock 180ml

It reminds me of something I was told by an American expat who was living in Japan, you can make any cuisine into Japanese food just by adding sugar.

You can observe the same phenomenon when you order an okonomiyaki with bonito flakes at a Japanese Izakaya.

A lot of food tastes like seafood in Japan, even though it may not be seafood itself. This is because the basis of Japanese cooking is dashi, which is the stock of kombu (kelp) and fish flakes, like bonito. It's called the flavour of the sea and dashi is used to boil vegies, it's mixed with the egg in omelettes and egg rolls, it's the broth used in miso soup, noodles and hot pots and much more. Even rice is boiled with some kombu, so it can have a seaweedy taste.

Dashi is easy to make and very good for you. Most young people in Japan use the instant dashi packs, but older women/men know how to make the real deal. I was fortunate to meet some older talented women who passed on a lot of their knowledge to me.

We eat pretty well, including home-style Japanese cooking about 2-3 times a week. Thanks go out to Kuri sama, Daisy and Mayumi san for their patience and care in teaching me to cook kateika ryori. Arigato gozaimasu! Taihen osewa ni natte imasu yo!

boo hoo for sazae-san......This video has been removed due to terms of use violation.

“nice work, maudlin, but not quite right:

'neko' means 'cat'. 'doraneko' means 'stray cat', and 'dora' (by itself) can also be used to mean 'stray cat' (just like 'tom' for 'tomcat' in english).

doraemon (this guy: http://www.shopro-entertainment.com/doraemon.html) is a cat-type robot from the 22nd century of the future. he's one of the most famous characters (manga/tv/advertising) in japan. he used to have cat ears, but they got bitten off by a mouse (in the future). the word 'dora' in his name is just like above.

many other characters and various items in "doraemon" are named 'dora-something', including the character you found. the reference is to doraemon himself.

"sazae-san" is a different show, also long-running and very popular. everybody watches it on sundays. the theme song starts with a verse about a 'doraneko' carrying fish and being chased by sazae-san. that's the question being answered by this experiment. everyone knows the sazae-san theme song, which is why this is so funny to japanese. they're taking the song very literally.

the experiment title comes from the song and is written in blue writing in the top right corner of the screen.

the conclusion of the clip you posted (starting with the writing against the sunrise over the earth) says:
'in this way a new piece of trivia is born into the world:'
'the [fish-stealing stray cat] that is chased by sazae-san can steal a maximum load of approximately a 2-kg bonito (fish)'

beautiful.
