After a sun-kissed day on the beach or before heading home, there’s nothing quite like soaking in a warm onsen to restore body and soul. Here are three handpicked hot springs—each with its own charm—located within a short 15–20 minute drive from Aquaholic Iritahama. Perfect for adding a touch of relaxation to your seaside getaway.
① Sennin-buro Kanaya Ryokan (Shimoda Onsen)
Step into history at Kanaya Ryokan, a beloved inn that has been soothing travelers for more than 150 years. Its legendary “Sennin-buro”—a vast bath made entirely of fragrant cypress—is said to be one of Japan’s oldest wooden baths. As you sink into the gently steaming water, surrounded by the soft scent of hinoki, the world outside simply fades away. The slightly hot, mineral-rich sulfate spring is pure and natural, flowing straight from the source and leaving your skin beautifully smooth.
