**Introduction** Arai Coast Embankment, located in the picturesque Tosa region of Japan, stretches gracefully with its moderately lengthy shores clad in subtle shades of beige sand. The coastline lacks traditional beach activities like surfing due to its unique geological attributes but remains a serene spot for walking, photography, and soaking in the tranquil atmosphere. Arai Coast Embankment has few amenities, so plan your trip accordingly, although it does not permit dogs, lacks facilities for disabled visitors, has no restrooms, and does not allow camping or nude beaching. This makes it essential for visitors to come prepared for a more natural and untouched beach experience, bringing their necessities and ensuring to leave no trace behind to preserve its pristine condition.
