The octopus and shellfish was harvested Friday during trial fishing off Fukushima prefecture by a local fishermen's cooperative in Soma and Futaba, The Mainichi Shimbun reported.
The products were put on sale after they passed radioactive tests conducted by the prefecture's fishing association. The test results were also displayed in the stores.
"It's soft and very tasty," said Hitomi Kamata, who tried some Pacific giant octopus at one store. "It's not that I'm not worried [about radioactive contamination], but because there was no radioactive material detected I think I can feel safe."
Another round of trial fishing is set for Wednesday, and those catches will be shipped outside the prefecture as well.
