An annual oceanic memorial service took place in Japan, during which family members said their final heartfelt goodbyes to their departed fathers. Sailors took vessels filled with mourners out to sea, where they released mementos into the ocean as part of the cultural mourning rite. This event continues to maintain its tradition each year, drawing significant attention within the Japanese society for its display of familial respect and remembrance.

In Japan, memorializing the deceased is a crucial part of their cultural and religious customs, and it involves various practices and ceremonies. Oceanic memorials are prevalent, particularly among families of sailors, fishermen, and others who spent their lives at sea. These intricate rites give the families a chance to pay their respects and remember their loved ones in a significant and sentimental way.

In comparison to the United States or the European Union, oceanic memorials are less common, though maritime communities in these regions also have specific ceremonies related to loss at sea. For example, the U.S conducts the ceremonial "Burial at Sea" for deceased military personnel, with similar respect and reverence dedicated to lives lost on the water.
