Children Who Chase Lost Voices streaming for free March 15th-17th
Children Who Chase Lost Voices is streaming for free over the weekend (Fri March 15th to Sun March 17th) over at Crunchyroll for those who have membership. Not sure if it's available for non-members, so for those who aren't you can try the free trial, or take out a month subscription pretty cheaply.
This is part of Global Shinkai Day, and includes the back catalogue of other Shinkai titles. This takes place every year, so for those who see this after the weekend, make a date in your diary for next year!
