Japanese Killer Bee or not killer Bee?

Do you think they were Japanese Killer Bees?

I had noticed whenever I open Net door to go to the balcony some very big bees started flying near door. I thought it could be by chance. But those bees were not normal they were very Big/Long that worried me. In short, one day I found out they had nest on the metal(a bracket used to hand cloth in Japan). In a protective way, I pushed that nest with a bar and that nest fell down on the floor.

Guess what? so many bees appeared out side of the (Net) door as they were angry at me. And many were coming out from the broken nest. From inside I used Bees killer spray but some did not die rather flew away. Next day they were still coming out of the nest so I used Bleach on the nest and forget them. After 3 weeks when today I wanted to take photos, some bees appeared from distance that is why I had taken very few photos.

Please take a look and inform me if they are Killer Bees? Do they remember if I am the one who messed with them?
