Shirahama Beach (白良浜, Shirarahama), in the town of Shirahama, Nishimuro District, Wakayama Prefecture, takes its name from the colour of its sand: "shirahama" literally means "white beach." The crescent-shaped bay is made up of more than 90% silica sand, giving it an almost dazzling brightness under the sun. It sits on the Pacific coast of the Kii Peninsula, roughly two-and-a-half to three hours by train from Osaka. The town has functioned as a resort since the 1920s, once known chiefly as a honeymoon destination in the post-war decades before becoming more of a family resort after Adventure World opened nearby in the 1990s.
Coastal development and natural erosion steadily wore the beach down through the 1960s and 1970s. To restore it, Wakayama Prefecture began importing sand from the Perth area of Western Australia in 1989 — local seabed sand was too dark to keep the beach's characteristic white colour. According to Japanese Wikipedia, the cumulative volume imported reached around 74,500 cubic metres by 2005. A shark net has also been in place offshore since 1992 for swimmer safety, and in 2000 Shirahama became a sister beach to Waikiki in Hawaii.
The swimming season traditionally opened as early as May 3rd — the earliest of any beach on Honshu — though in recent years the opening has shifted to early July because of a shortage of available lifeguards. Japanese Wikipedia reports that the beach draws more than 600,000 visitors during the peak summer season and close to one million across the year — figures as reported by that source, not independently confirmed or necessarily current. Shirahama was named among Japan's 100 best beaches in 1996 and among the Ministry of the Environment's 100 best swimming spots in 2006.
The beach sits inside Nanki-Shirahama Onsen, one of the country's oldest hot spring resorts. Its waters — chloride and hydrogen-carbonate springs ranging from 32°C to 85°C — are recorded in the eighth-century Nihon Shoki chronicle, which describes visits by Emperor Saimei in 658, Empress Jito in 690 and Emperor Monmu in 701; the Man'yoshu refers to the springs by their old name, "Muro no Yu." For centuries, Nanki-Shirahama was counted among Japan's "three great hot springs," alongside Atami and Beppu. One of its best-known baths, Sakinoyu, is an open-air rock pool facing directly onto the Pacific — tradition holds that Emperor Saimei and Crown Prince Nakanoe bathed there in 658, and the Edo-period feudal lord Tokugawa Yoshimune later did the same. Because of its exposure to the sea, Sakinoyu occasionally closes when waves are rough. For travellers who want to stay close to both the beach and the springs, the Yanagiya ryokan is one of the lodging options in the area.
Close by are some of the most photographed spots on the Wakayama coast: the Sandanbeki cliffs, roughly 50 metres of basalt rising straight from the sea; the Engetsu-tō natural arch, a small rocky island pierced by the water; and Senjō-jiki, a tiered sedimentary rock shelf at the water's edge. Families often combine a beach day with Adventure World, a nearby safari park and aquarium. The area is served by Nanki-Shirahama Airport and the JR Kisei Main Line to Shirahama Station, which has connected the resort to Osaka by rail since the 1960s — the direct journey from Shin-Osaka Station takes around two-and-a-half to three hours.

Yes. Since 1989, Wakayama Prefecture has imported sand from the Perth area of Western Australia to offset coastal erosion; according to Japanese Wikipedia, the cumulative volume reached around 74,500 cubic metres by 2005.
The swimming season traditionally opened on May 3rd, but in recent years it has typically started in early July because of a shortage of lifeguards — worth confirming exact dates before travelling.
By train on the JR Kisei Main Line, with a direct connection from Shin-Osaka Station (roughly 2.5 to 3 hours); the area is also served by Nanki-Shirahama Airport.
Yes — the beach sits inside Nanki-Shirahama Onsen, one of Japan's oldest hot spring resorts, which includes the historic open-air Sakinoyu bath facing the ocean.
