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 ShopLocationPriceHoursGear Included
Zushi SUP ClubNear Zushi Beach¥3,000/2hr9:00–17:00Board, paddle, life jacket
Hayama PaddleIsshiki Coast¥3,500/2hr9:00–18:00 (summer)Board, paddle, leash, dry bag
Beach House KAIZushi Beach (east)¥4,000/2hr (with lesson)9:00–17:00Beginner 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 ShopLocationPriceDuration
Zushi Marine SportsZushi Beach¥3,500 (single) / ¥5,000 (double)2 hours
Hayama Water ClubHayama 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.

6. Windsurfing

Windsurfing is popular at Isshiki Beach and Zushi Beach, where the afternoon seabreeze (12–16 knots in summer) creates good planing conditions.

Best for: Intermediate to advanced windsurfers who want consistent afternoon wind without the crowds of Enoshima. Beginners should book a lesson.

7. Fishing Charters

The waters off Zushi and Hayama are rich fishing grounds, with the Miura Peninsula's underwater topography attracting a variety of species.

CharterTypePriceDurationTarget Fish
Zushi FishingShore + boat¥8,000 (half-day boat)4 hoursSea bream, flounder, horse mackerel

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 coloured 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 ShopTypePrice (2-tank)Tanks IncludedBest Season
Shonan Dive CenterShore diving (Chojagasaki)¥12,000✅ Air fillsJune–October
Hayama DiveBoat diving¥18,000✅ Air fillsJuly–September

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

10. Offshore Kayaking (Sea Kayak)

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 Rental: Hayama Water Club offers sea kayaks (¥5,000/half-day) for experienced paddlers
