Toyama Prefecture sits on the Sea of Japan coast of central Honshu, framed by the dramatic Tateyama mountain range and the deep waters of Toyama Bay. Home to the Tateyama Kurobe Alpine Route, one of the world's great high-mountain crossings, and the UNESCO-listed gassho-zukuri thatched-roof villages of Gokayama, Toyama pairs alpine scenery with a coastline famous for firefly squid and glass shrimp, plus a proud tradition of glassmaking and sake brewing in its historic port town of Toyama City.

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 Toyama’s coast.
Is Amaharashi Coast Beach good for swimming with children?
The water is shallow and calm near the pine grove, making it suitable for young children, but there is no lifeguard on duty so adults should supervise closely.
From the Amaharashi Coast Beach editorial.
When is the best time to see the Tateyama mountains from the beach?
Clear winter mornings, especially after a cold front passes, offer the sharpest views of the snow-capped range across Toyama Bay.
From the Amaharashi Coast Beach editorial.
How do you get to Iwasehama Beach without a car?
Toyama Light Rail's Portram line runs from Toyama Station's north exit to Iwasehama Station in about 25 minutes, followed by a five-minute walk to the shore.
From the Iwasehama Beach editorial.
Is Iwasehama Beach crowded in summer?
It draws mostly local residents rather than tourists, so it stays calmer than more famous beaches even during the July-August swimming season.
From the Iwasehama Beach editorial.
How do you get to Shimao Beach?
Take the Ainokaze Toyama Railway from Toyama Station to Takaoka, transfer to the JR Himi Line to Himi Station, then take a taxi or rental car for the final 15 minutes to the beach.
From the Shimao Beach editorial.
Can you camp at Shimao Beach?
Yes, an adjacent campsite serves overnight visitors, particularly during the summer swimming season.
From the Shimao Beach editorial.
What is special about Miyazaki-Sakai Beach?
It is a 4 km pebble beach nicknamed the Jade Coast, where visitors search for jade and other semi-precious stones washed up after rough seas.
From the Miyazaki-Sakai Beach (Jade Beach) editorial.
Is Miyazaki-Sakai Beach sandy?
No, it is a pebble beach rather than sand, so water shoes are recommended for both swimming and stone hunting.
