The Sea Alms tradition or what is called the Lomban Festival is carried out by the Jepara community as a form of gratitude for the abundance of marine products by the fishing community. This tradition has an interesting element for the community, especially in the procession of throwing the buffalo head as an expression of gratitude and accompanied by traditional fishermen's dances. The sea alms procession in Jepara depicts Islamic culture. This procession has similarities with the sea festival in East Asian countries (Japan), namely the Hamaori Festival which is identical to Buddhism. This study has a scope of two regions in two countries, namely Jepara, Indonesia and Kanagawa, Japan. In short, the concept of the Jepara sea alms tradition means bringing agricultural products to be thrown into the sea, while the Hamaouri festival in Kanagawa means carrying a temple stretcher to be taken to the sea containing agricultural products as an expression of gratitude. The method used in this study is the historical method, namely heuristics, criticism, interpretation, and historiography. The results and conclusions in this study show that based on the two traditional ceremonies based on the sea, namely the sea alms, Jepara, Indonesia and Hamaori, Kanagawa, Japan, they show the same goal, namely expressing gratitude for the abundance of marine products, even though they have differences in culture, religion and the processions behind them, and both have the potential to become international tourism destinations.
