What are the ingredients used in this issen yoshoku video?

Hello everyone :) I'm looking for help to identify the ingredients that go into the preparation in this video:

This appears to be a type of okonomiyaki, however the recipe seems rather different from the ones I can find online. Below I will list the ingredients in order of appearance. Around 1:58 there is a cut in the video but they also show the okonomiyaki up close. I would be grateful if any of you could provide some assistance. :)

EDIT: This appears to be an unusual type of okonomiyaki known as issen yoshoku (壹錢洋食). Using this name I could find this post, where they have a list of ingredients. However I'm not sure if/how they correspond to the ingredients in the video.

1. Okonomiyaki batter Batter: wheat flour and water (?)
2. Just on top of the batter: Katsuobushi (?)
3. Spring onions or maybe leek (?)
4. Eggs
5. White stuff: Some kind of cheese or maybe tempura scraps (tenkasu) (?)
6. Red stuff: Benishoga or sakura shrimp or both (?)
7. Black stuff: perhaps seasoned konnyaku (?)
8. White rings: perhaps kamaboko (?)
9. Meat
10. At the very end, I imagine okonomiyaki sauce or maybe .
