This is one of the best things anyone interested in one of the most impressive engineering marvels ever can go and visit anywhere in the world. I cannot stress enough how good it is and how involved the tour gets (wearing waders to go waist deep in water to view the jet turbines used to pump water).

I strongly advise taking someone who can help translate Japanese with you as there's a huge amount of information to take in and it's a fantastic opportunity for anyone keen on photography as well.
