All of these changes are incorrect. You damaged Tokyo's boundary relation. And you added fountain tag to the wrong features in the 9/11 memorial in NYC. Fountain is already tagged there. You tagged incorrect element.
In the future, please, pay closer attention to what you are mapping, *especially* such high-profile places as NYC and Tokyo.

All of these changes will be reverted in full.
