Because it's a good 800 km from Tokyo, and 4 hours one-way even by bullet train. And because, A-bomb sites and Miyajima aside, there's not all that much of interest in the city of nearby.

On the other side of the coin, I also find it a bit odd to describe Hiroshima as a cliché. Quite the opposite, it's near-unique: Hiroshima and Nagasaki are the only cities ever attacked with nuclear bombs, and you can't get the experience of visiting them anywhere else.

Yeah 4 hours by bullet train, and $185 each way. Plenty of people haven't been there.

Tourists would at most spend $267 for the seven-day JR pass.

Just as a reminder for people interested in buying JR pass: 1) not all trains all included (fastest Shinkansen Nozomi is not for example) 2) can't be bought in Japan 3) valid for 7/14/21 days from the first use
