Nagasaki is a port city on Japan's Kyushu island with a uniquely layered history — centuries of trade with China, Portugal, and the Netherlands left behind temples, cathedrals, and Western-style mansions, while August 9, 1945 marked it as the second city struck by an atomic bomb. Today Nagasaki blends solemn peace memorials with lively Chinatown streets, hillside tram rides, and some of Japan's most distinctive cuisine.

Beach safety
Hard-earned guidance — read this before you swim, especially if you’re unfamiliar with the coast.
Critical
Swim where lifeguards are posted and follow flag warnings — green is safe, yellow is caution, red means no swimming. Rip currents are the leading beach hazard worldwide.
Caution
Watch for tide changes and marine life — jellyfish blooms, sea urchins on rocky entries, occasional shark or stingray advisories. Don’t swim alone, especially at dawn or dusk.
Tip
Reapply sunscreen every 90 minutes and after every swim. Take shade between 11 am and 3 pm — the sun is harsher than people expect, even when the air is cool.
Practical
Keep valuables out of sight or back at the accommodation. Beach theft is a small-but-real risk at busy beaches; never leave bags unattended while you’re in the water.
Common questions
Quick answers to the questions we get asked most about Nagasaki’s coast.
How do visitors get to Iojima Beach?
The only way to reach Iojima Beach is by the Iojima Ferry from Motofuna Pier in Nagasaki, a roughly 25-minute crossing costing about ¥340 ($2.21) one way.
From the Iojima Beach editorial.
Is Iojima Beach suitable for young children?
The cove is sheltered from major swell and generally calm, making it reasonable for supervised family swimming, though there is no lifeguard on duty.
From the Iojima Beach editorial.
Is Mogi Beach a good spot for swimming?
The water is calm and sheltered, suitable for casual swimming, though the shoreline is modest and partly rocky near the pier rather than a long sandy stretch.
From the Mogi Beach editorial.
What is Mogi known for besides the beach?
The area is a working fishing district, and its seaside restaurants and fishing pier are as much of a draw as the beach itself.
From the Mogi Beach editorial.
How long does it take to reach Nomozaki Beach from Nagasaki?
The bus from Nagasaki Station takes about 75 minutes and costs approximately ¥820 ($5.33) each way; there is no direct rail option.
From the Nomozaki Beach editorial.
Is Nomozaki Beach crowded?
It is generally quiet, drawing far fewer visitors than city-adjacent beaches, since it sits at the remote tip of the Nomozaki Peninsula.
From the Nomozaki Beach editorial.
How do visitors get to Kashiwajima Beach?
The route is a high-speed jetfoil from Nagasaki Port Terminal to Fukue Island (about 1 hour 50 minutes, ¥4,400/$28.60 one way), followed by local transport to the beach itself.
From the Kashiwajima Beach (Goto Islands) editorial.
Is Kashiwajima Beach good for snorkeling?
Yes, the clear, calm water and rocky points at either end of the cove make it one of the better snorkeling beaches in the Goto Islands.
