Happy Taiku no hi

As we Americans were celebrating our politically-incorrect holiday today, the Japanese appeared to be celebrating an equally banal holiday - taiku no hi, or Sports Day.  I was completely unaware that the Japanese had a holiday today until I took the kids and Stevie (on his first outing in four days) to a Japanese park.  It was crazy busy!  The kids all playing at the playground, families paddling in paddle boats, playing basketball, riding bikes, etc.  So I asked the Japanese guard on the gate as we returned home, what holiday is it?  In his limited English he tells me what sounded like "walk-out day".  Walk out day?  Does everyone walk off their jobs???  Nooo, he was trying to say "work-out day"!  So I promptly came home to Google it and discovered it is actually "Sports Day".  No wonder the Japanese are so thin, they actually have national holidays that promote physical fitness!
