I would never ever understand Japanese and their obsession with mixing raw egg with hot rice. First, that just disgusting both appearance and smell. Second, SALMONELLA, DUDE!!!
"But, Japanese egg is safe to eat because the Japanese egg is bla bla bla."
That's also what they said with Korean enoki and yet people still get food poisoning even with proper cooking.
It's not safe, but it's delicious
Chances of actually getting salmonella is pretty low, and the most recent 'outbreak' is like only arond a hundred, with only half confirmed, and about only a dozen requiring hospitalization.
Is the risk worth it? Seeing how it's so low that it's practically a once in a lifetime chance it's basically nothing at all.
Keep your egg refrigerated, get it from ones that pasteurizes them, prepare it responsibly.
If you have digestion issues then probably think more, but for everyone else it's basically, if not perfectly, fine.
