Monster Zero x SciFi Japan - Archive Only

I don't know if they count as product placement because they were a bit subtle but those are that i can recall:

Nikon: Mark's camera when taking pictures of wolves.
AOC: Big monitors on submarine base.
Dell: monitors on Monarch Boston outpost (Emma's videoconference)
Dunkin' Donuts: billboard destroyed by Godzilla.
Fenway Park and Boston Red Sox?

Any other product that you spotted?

I spotted all the products placement that you mentioned Ultraseven. I didn't spot any more.

I noticed that Madison had Rick & Morty stickers on her laptop, although I don't recall what brand of computer it was.
