Never knew about Michiko and Hatchin, I'll watch it later, it seems interesting.
And the only media thing I know that shows a little bit about Brazilian-Japanese culture, is a short tv series that was transmitted here on 2008, as part of the 100 years anniversary of Japanase immigration to Brazil, Haru to Natsu todokanakatta tegami or as in Portuguese: Haru e Natsu, as cartas que não chegaram.
Offtopic fact, the author of No Game No Life, is Brazilian.
