A few Things to know:
1. You can only get your tickets through an onsite agency or NOW a specific online agency offered on their site
2. You would need to pick your day in advance and there is only a set amount of people who can go on that day
3. You need to be prepared to do a lot of walking, (Unless you are in a wheelchair which they do have available) there is no parking to discourage cars
4. They make it clear that there is no Photography allowed
There are a few other things, but you are welcome to check them out in more depth:

For anyone curious I had done a conversion to get an idea of the base prices before taxes and fees
Adults (19+) = ¥1,000 about $8.86 ($9.00)
Teens (13 - 18) = ¥700 about $6.20 ($7.00)
Pre Teens (7 - 12) = ¥400 about $3.54 ($4.00)
Kids (4 - 6) = ¥100 about $0.89 ($1.00)
younger (3 and under) = FREE
