Meet the Giant Salamander—Kyoto’s surprising local superstar.

In the heart of Kyoto Aquarium, you’ll find a massive creature that barely moves and looks like a mossy boulder: the Japanese giant salamander (Andrias japonicus). It may not be cute or flashy, but this gentle giant is one of Kyoto’s most iconic—and mysterious—residents. This species is endemic to Japan, and particularly associated with the Kamo River in Kyoto. It's been around for over 20 million years, making it a literal living fossil. The giant salamander can grow up to 1.5 meters long, breathe through its skin, and live quietly for decades. Kyoto Aquarium has one of the largest public displays of giant salamanders in the country, and it’s taken seriously: their habitat is carefully temperature-controlled to mimic cold mountain streams. Some salamanders here are over 30 years old! But there’s also a lighter side. The aquarium sells cute giant salamander plushies, and even Kyoto’s manhole covers feature their squishy little faces. Locals call them “Hanzaki-san” with affection. So whether you’re a wildlife nerd or just love weird-looking animals, don’t miss Kyoto’s most ancient resident—you might even say he's the real emperor of the aquarium.
