This may not be well known outside of the two respective countries, but there are pretty strong historical and cultural ties between Japan and Brazil. There was a wave of emigration from Japan to Brazil in the early part of the 20th century and later on around the '50s and '60s. And in the last 30 years, many Brazilians of Japanese descent (people of Japanese descent born in another country are called nikkei-jin) have in turn emigrated to Japan to fill labor shortages. Perhaps because of this, a few years ago one of the staples of the Brazilian diet, pao de queijo, little cheese breads, became very popular. While their popularity may have descended a bit from their peaks (Japan tends to be periodically swept up by big food or fashion trends, which after a time get dropped without warning when people move onto the next thing, but that's another story), they are still made by bakers throughout Japan.
I think that pao de queijo appeals so much to the Japanese palate because they are small, round and cute, and have a distinctive gooey-sticky-glutinous kind of texture inside. This texture is called mochi mochi, after mochi, the very gooey-glutinous rice cakes.
