that a Japanese diver has maintained a friendship for over 30 years with a fish under the sea?
In Tateyama Bay, Japan , diver Hiroyuki Arakawa has developed an extraordinary bond with Yoriko, a Semicossyphus reticulatus (giant wrasse). This friendship began more than 30 years ago when Arakawa rescued Yoriko, who was injured , and cared for her by feeding her crabs until she recovered. Since then, they’ve been meeting regularly at an underwater Shinto shrine that Hiroyuki lovingly protects.
What makes this story even more amazing is that Yoriko recognizes Hiroyuki and swims towards him every time she hears his familiar underwater tapping . Scientists have documented this behavior and recorded videos showing how Yoriko even allows Hiroyuki to give her a gentle “kiss” on the head , a beautiful sign of trust and affection .
Giant wrasses like Yoriko are known for their long lifespans and intelligence . Scientific studies have shown that some fish species can recognize human faces and remember relationships for many years . For example, researchers at the University of Oxford demonstrated that certain fish can distinguish and recall human faces with surprising accuracy.
Now in his 70s, Hiroyuki continues to dive regularly to greet his friend , showing us that loyalty and kindness aren’t limited to land animals . Their story has inspired documentaries , attracted visitors , and become a symbol of empathy and connection between humans and marine life .
