Undocumented mark that's similar to WP #31 'Chohokei' or 'Ichi' except that it has 3 Dots aligned along one of the sides of the rectangle plus 2 Dots that are located on the edge of the seal button.

Since the primary symbol is Ichi in a Box, I'm assuming it was produced by the Nichiro Fishing Company on Hokkaido Island, Japan.
