Costa de Uradome

**Kayaking tour selection:** Their 3-hour morning tour (9:00–12:00, ¥7,000) includes cave exploration, cliff-base paddling, and a private beach stop for swimming and snorkeling. The afternoon tour (13:00–16:00) encounters rougher sea conditions — beginners should take the morning slot. Maximum 8 participants per guide ensures personalized attention. **Cave exploration:** The highlight is Ajiro Cave (網代の洞窟), a 50-meter sea cave that penetrates completely through the cliff headland. Kayaking through in near-darkness while waves echo off basalt walls creates a genuinely thrilling moment. The cave is accessible only 2 hours before/after high tide — tour timing coordinates with tidal schedules. **Snorkeling conditions:** Bring your own mask and snorkel (rental available but basic). The coves host rocky reef fish — black rockfish, sea bream, schools of juvenile sardines — plus occasional encounters with jellyfish (harmless moon jellies). Water temperature: 18–24°C May–September. Visibility best in June–July before summer plankton blooms. **Photography from water:** Most phones are not waterproof enough for kayaking splashes. Bring a simple waterproof camera or GoPro. The most photogenic moment: paddling beneath the Sengan Matsushima rock arch with the cliff face towering 40 meters overhead, backlit by morning sun. **Combine with coastal trail:** The Uradome Coast Trail runs 6 km from Iwami Station to Cape Ajiro with clifftop viewpoints overlooking the kayaking route. Hike in the morning (2 hours), kayak in the afternoon for two perspectives on the same landscape. The Uradome Visitor Center (free entry) explains the volcanic geology with excellent English signage.
