On June 23, 2011, Japan Post issued a sheet of 10 stamps marking the 50th anniversary of the start of the Antarctic Treaty. Ratified on December 1, 1959, the treaty went into force on June 23, 1961. The sheet from Japan contains five map 80JPY denomination stamps, of a common design, shown on the left. The continent of Antarctica is shown with a group of snow flakes, along with text at the top of the stamp marking the 50th anniversary of the start of the treaty. The map stamps share the sheet with five unique stamps of penguins.
