Vegan and Vegetarian restaurant finder HappyCow

I am not vegetarian or vegan, but sometimes people who are ask how to find restaurants that serve that category of food, especially when traveling.
I’ve recently come across HappyCow, which has a website as well as Android and iOS apps which would seem handy for the food fan on the go.

For example, they list 4450 places in Japan.

I haven’t tested it much, so if the TOS is onerous or it sucks overall, etc. I preemptively apologize, but it seems like a good resource.
