Activities by Skill Level
🟢 Beginner-Friendly (No Experience Needed)
1. Stand-Up Paddleboarding (SUP)
SUP is the most accessible marine activity on this coast. The sheltered waters of Zushi Beach and Isshiki Coast provide calm conditions ideal for first-timers.
| Rental Shop | Location | Price | Hours | Gear Included |
|---|---|---|---|---|
| Zushi SUP Club | Near Zushi Beach | ¥3,000/2hr | 9:00–17:00 | Board, paddle, life jacket |
| Hayama Paddle | Isshiki Coast | ¥3,500/2hr | 9:00–18:00 (summer) | Board, paddle, leash, dry bag |
| Beach House KAI | Zushi Beach (east) | ¥4,000/2hr (with lesson) | 9:00–17:00 | Beginner lesson included |
Best conditions: Calm mornings (8–11 AM) before the sea breeze picks up. Summer weekdays offer glassy water with minimal boat traffic.
📍 Pro tip: Start at Isshiki Beach — the water is shallower and the bay is better protected than Zushi Beach’s open stretch. Paddle east along the coast for views of the Imperial Villa’s forested grounds.
2. Kayaking (Sit-on-Top)
Sit-on-top kayaks are the most popular rental option and require no previous experience. The short crossing between Zushi Beach and Morito Bay is an ideal 30-minute route.
| Rental Shop | Location | Price | Duration |
|---|---|---|---|
| Zushi Marine Sports | Zushi Beach | ¥3,500 (single) / ¥5,000 (double) | 2 hours |
| Hayama Water Club | Hayama Marina | ¥3,000 (single) | 1.5 hours |
Recommended route: Paddle from Zushi Beach south along the coast toward Morito Bay (2 km, ~30 minutes). Stop at Morito Beach for a break, then paddle back. The coastal views of the Miura Peninsula hills are excellent.
3. Snorkeling
Snorkeling is best at the rocky edges of Shibasaki Beach and around the Chojagasaki promontory. Water visibility ranges from 5–10 metres on calm summer days.
Best spots:
- Shibasaki Beach — Rocky shelves with small fish, hermit crabs, sea anemones. Go at low tide for the warmest, clearest pools.
- Chojagasaki — Rocky coves with better fish variety but stronger currents. Stay close to shore.
- Morito Shrine island — The channel between the shrine island and mainland has some marine life but limited visibility. Rental: Snorkel sets are available at Zushi Marine Sports (¥1,000/day). Bring reef shoes — the rocks are sharp.
4. Beach Swimming
| Beach | Swimming Quality | Lifeguards | Facilities | Best For |
|---|---|---|---|---|
| Zushi Beach | ⭐⭐⭐⭐ Good | ✅ July–August | Beach houses, showers | Families, casual swimmers |
| Isshiki Beach (Hayama) | ⭐⭐⭐⭐⭐ Excellent | ✅ July–August | Blue Moon beach club, showers | Best all-round beach |

8. Open Water Swimming
The Zushi–Hayama coast is a training ground for open water swimmers, particularly the 2 km crossing between Zushi Beach and Morito Bay. Route: Zushi Beach → Morito Bay (2 km, ~40–60 minutes depending on conditions)
⚠️ Important:
- Swim only on calm days with no offshore wind
- Wear a brightly colored swim buoy for visibility
- Go with a buddy — currents can be stronger than they appear
- Check tide tables: outgoing tide creates a slight north-to-south drift
- Best conditions: June–September, early morning (6–9 AM)
9. Scuba Diving
Diving in Sagami Bay is limited by visibility (typically 5–12 metres) but offers interesting macro life and easy shore access.
| Dive Shop | Type | Price (2-tank) | Tanks Included | Best Season |
|---|---|---|---|---|
| Shonan Dive Center | Shore diving (Chojagasaki) | ¥12,000 | ✅ Air fills | June–October |

Marine life: Octopus, lionfish, sea slugs, moray eels, and occasional sea turtles. The rocky reefs at Chojagasaki are the most reliable shore diving spot.

Experienced kayakers can paddle the full 6 km stretch from Zushi Beach down to Chojagasaki and back. This is a 3–4 hour trip requiring good fitness and awareness of wind conditions.
Route: Zushi Beach → Isshiki → Morito → Chojagasaki (round trip: ~12 km)
Best conditions: Calm mornings with forecast wind under 10 knots

Frequently Asked Questions

Q: Are there changing facilities and showers at the beaches?
