Suikawari, or “watermelon splitting,” is a traditional Japanese summer game similar to the Mexican piñata. Players are blindfolded, spun around, and guided by friends as they try to hit a watermelon with a wooden stick or sword. The game is typically played on the beach or in a backyard. Participants take turns aiming for the watermelon. The first to crack open the watermelon wins; everyone can enjoy the juicy fruit together!

This game is a popular activity during Japanese summer festivals and gatherings, providing fun and refreshments on hot days. It’s often placed on a plastic sheet or cardboard to keep the watermelon clean. The excitement from the attempts to follow shouted directions leads to laughter and entertainment! Suikawari strengthens bonds through teamwork and offers a delicious treat at the end!
There are various theories about the origins of suikawari. Traders introduced watermelon, a fruit native to Africa, to Japan via China during the Edo period (1603-1868). Some historians theorize that African traditions inspired the Japanese practice, where people cracked open watermelons to pray for an abundant harvest. Other theories include the legendary beachside duel in 1612 between samurai swordsmen Musashi Miyamoto and Kojirō Sasaki.

Some believe that after Sasaki’s defeat, his ghost appeared as a watermelon, which Miyamoto smashed to drive away his spirit. Another story claims that samurai used watermelons for target practice with wooden swords, closing their eyes to train. Historians claim that Feudal Lord Hideyoshi Toyotomi introduced the game to boost morale among workers during the construction of Azuchi Castle in the late 1500s.

In 1991, the Japanese Agricultural Society established rules for suikawari, creating the Japan Suika-Wari Association. The rules specify the player should stand 5-7 meters (16-23 feet) from the watermelon and use a stick with a circumference of 5 cm (2 in) and a length of 120 cm. (47 in). Players must use a domestic watermelon and wear blindfolds. Each player has a 3-minute time limit, and judges award points with a maximum of 10 points for a clean split.

The JSWA’s rules also stipulate that players must conduct the game on a beach or grassy field. Additionally, other participants must spin the blindfolded player around before they attempt to smash the watermelon. The referee must demonstrate a passion for watermelons by answering specific questions. Although the JSWA is now inactive, these rules helped standardize suikawari, making it a popular and organized summer activity in Japan.
Suikawari has appeared in popular culture. The main character, Ranma, participates in a martial arts watermelon-splitting contest in the Ranma ½ manga. Contestants race to the finish line while protecting their watermelons. They also try to break their opponents’ melons. In another storyline, Tatewaki Kunō trains on Watermelon Island. He smashes watermelons falling from a waterfall. This training boosts his strength and speed when he sees a watermelon

Other examples include Azumanga Daioh, where the cast attempt to split a watermelon on the beach, and the anime Bleach, which features a monster made of watermelon in a beach episode. Video games also incorporate suikawari, such as Super Mario Sunshine, where players can smash giant watermelons for coins, and Wii Sports Resort, which includes watermelon slicing in the Speed Slice game.
