Because of the state of the world I wanted to watch an old series called Jericho. It's a show from 2007 about nuclear bomb attacks on the US and the aftermath in a small town in Kansas. https://www.imdb.com/title/tt0805663/
It got me thinking, how bad would a nuke be if it hit Tokyo. There are a lot of variables like the yield of the device, kiloton, megaton, the altitude it's detonated at, etc. Luckily someone created a web based tool that can calculate the devastation by inputing a lot of those variables or use their auto variables. Looks like I would survive a blast in Tokyo as long as they don't hit the air force base near my home.
Give it a try yourself and pray.
