I really respect and love works of Japanese director Kawase Naomi. I saw her works in beginning of 2000 in Helsinki Ateneum. I was stunned to hear about her adoption (she was adopted when she was two, just like me). It could be because of this reason that I am so moved about her work.
My personal favorite is Mogari no Mori (Mourning Forest 2007) but I also love her earlier work Katatsumori and Embracing. She is fearless and honest documentarist.
