Is Hachijojima the world’s northernmost breeding area for humpback whales?


The number of humpback whales has been increasing around Hachijojima. Surprisingly, according to the survey by Tokyo University of Marine Science and Technology and Hachijomachi, there is a possibility that Hachijojima is their northernmost breeding area in the world! The survey is still underway. If you see a humpback whale, please tweet with hashtags “#Hachijojima (八丈島),” “#humpback whale (ザトウクジラ),” and “#discover (発見).” We are looking forward to hearing from your witness report!
