Sunday we went to Yoyogi Park to try to see cosplays, but we failed to see it. Fortunately, to make up for it we saw a Festival of Saint Patrick. The festival was held on March 20 for a festive St. Patrick normally on the March 17. This is probably to have more people on a Sunday. Otherwise it's work / work ;)
You can buy lots of goodies, hats, head ribbons, pins, etc ...
You can enjoy the atmosphere and Celtic music to dance, drink a beer or eat a sheep chili with tacos.
We were a little disappointed not to see cosplays, but the festival was very nice. It's worth going there. One thing is certain is that this is only a postponement. We will try again seing colsplays ! :D
