Counting the waves…
Counting the waves…
The name promises gemstones; the reality delivers geology. A dozen volcanic plugs, some narrow as chimneys and others broad as garden sheds, stand in the shallows like a giant's forgotten game of Go. Wave action has carved windows and arches through the softer layers, creating frames within frames when you line up your shot. At low tide you can walk the sandbars between them, shoes squelching, and run your hands over basalt pocked with air bubbles frozen mid-escape millennia ago. Photographers arrive two hours before sunset and stake positions, tripods sinking slightly in damp sand. The light goes honey, then persimmon, then arterial red. The stacks turn to pure silhouette, black cutouts against a sky doing its full repertoire. Couples pose in the foreground; someone's always flying a drone. You'll want the spectacle despite the crowd—the way the sun catches in the rock windows, the sudden flare when it drops behind the offshore stack, the afterglow that turns the wet sand into a mirror. By full dark the beach empties fast. The rocks become vague shapes, blacker than the water, marked only by the white froth where swells fracture against their bases. The sodium lights from Mihama town glow orange two kilometers down the coast. You leave footprints the tide will smooth by morning.

Diamond Beach is generally safe for swimming during calm weather, but be mindful of the unique rock formations that give the beach its character. These rocks can create unpredictable currents in certain areas. Swimming is most recommended during summer months when lifeguards are typically present. Always check local conditions before entering the water, especially after storms or during high winds. The rocky areas are best appreciated from shore rather than navigated while swimming.
Diamond Beach is renowned for spectacular sunsets, with the best viewing periods from late spring through autumn (May to October). Summer evenings offer the longest daylight, while autumn provides clearer skies and more dramatic colors. Arrive at least 30 minutes before sunset to secure a good position and capture the changing light on the rock formations. The beach faces west, making it ideal for sunset shots. Golden hour during these months creates particularly Instagrammable moments that justify the beach's reputation.
Diamond Beach is located in Mihama, Fukui Prefecture, along the Wakasa Bay coast. The most convenient access is by car, as public transportation options are limited in this coastal area. If using public transport, take the JR Obama Line to Mihama Station, then a local bus or taxi to the beach. Driving from Fukui City takes approximately 90 minutes. Parking is available near the beach, though it can fill quickly during peak summer weekends and sunset hours.
Mihama offers various accommodation options ranging from traditional Japanese inns (ryokan) to modern hotels, many featuring fresh Wakasa Bay seafood. Several guesthouses and minshuku provide budget-friendly stays with home-cooked meals. The town has local restaurants serving regional specialties, particularly seafood caught from Wakasa Bay. For more dining variety, the nearby Obama City offers additional choices. During peak season, booking accommodations in advance is strongly recommended, especially if you want beachfront or sunset-view rooms.
The dramatic rock formations at Diamond Beach create distinctive silhouettes against sunset skies, making them the beach's signature feature. These naturally sculpted rocks have been shaped by wave action over thousands of years, creating photogenic formations that appear to sparkle during certain light conditions—hence the "diamond" name. The rocks provide excellent foreground subjects for photography and add character that distinguishes this beach from other sandy stretches along the Fukui coast. They're particularly striking during golden hour.
