Sea to Summit — Hatsukaichi, Hiroshima
One hour north of Miyajima's famous floating gate, the same city rises into the Nishi-Chugoku highlands. Pray at a thousand-year-old shrine on a sacred island. The next morning, draw a bow in the forest and light a fire with your hands.
Begin the ascentOne city, two worlds
Once the day-trippers board the last ferries, the island belongs to those who stayed. Stone lanterns are lit. You hear only waves and the footfall of deer. A thousand years of prayer, and no one to share it with.
The following day, a thousand metres up. You kneel, you breathe on an ember, and the moment it catches you look up — and someone is watching with you. Here, the mountain is something people do together.
The ascent — one hour, vertical
0 m — Miyajima
Salt in the air, the vermilion gate standing in the sea, a thousand years of worship. This is where the journey starts. Leave the World Heritage shoreline behind; the road turns north.
+30 min — Saiki
Thirty minutes north of the coast lies Saiki: rice terraces, clear streams, cedar shade. Children wade in the shallows while woodsmoke drifts through shafts of light. This valley is also the birthplace of Hiroshima salmon — the Banko Gorge fishing grounds are here.
+60 min — Yoshiwa, 750–1,000 m
Thirty minutes further. At 750 to 1,000 metres, Mominoki Forest Park opens across roughly 400 hectares — named one of Japan's 100 finest forests for shinrin-yoku (forest bathing). Ahead stands Mt. Kanmuri, at 1,339 m the second-highest peak in Hiroshima Prefecture. Launch from a platform 14 metres up a tree, glide 150 metres through the canopy, and the seaside feels like another country.
Raising a bamboo frame — the forest is a playground, and a classroom.
What makes it adventure
Nature
Old forest, mountain streams, and Hiroshima's second-highest peak. A designated heavy-snowfall zone where the average temperature runs more than 5°C below the city — real mountain weather, an hour from the sea.
Activity
Forest archery. A zipline over 150 metres long. A 6.18 km highland cycling road. Stream fishing in summer, snowfields in winter. The same forest changes its clothes four times a year.
Culture
Hand to hand, person to person. And an hour down the mountain: Miyajima, an island worshipped as a deity itself. Adventure inside a thousand-year-old sacred landscape — that is what makes Hatsukaichi unlike anywhere else.
Adventure tourism is defined as travel combining at least two of three elements: nature, physical activity, and cultural experience (per the ATTA/JNTO definition). Hatsukaichi holds all three within a single hour's drive.
A day in the forest
This is not a day of visiting attractions. It is a day of using your hands, touching fire, and spending hours in the company of others. One hour from a World Heritage island.
Four seasons, one field
Green & autumn
Treetop courses 8 to 14 metres up, ziplines through the canopy, a highland cycling road, and over 100 camping pitches. One of Japan's 100 finest forests for forest bathing becomes, in its entirety, a field of play.
White season
In winter this designated heavy-snowfall zone becomes a white plain. Snowshoeing, snow play, silence. An hour from the mild Seto Inland Sea, you arrive in snow country — a fact most visitors to Hiroshima never learn.
Stay in the highlands
Spend one night on the island; the next, go up. Stars overhead, birdsong at dawn. The lodge sits within the forest itself — open your eyes and you are already in the field.
One night on Miyajima, one or two in Yoshiwa. Sea and mountain, prayer and adventure — a single journey.
For seasoned adventurers
You have hiked the northern wilds and the alpine towns. What is different here is not the forest — it is the doorway. In the morning you stand before a thousand-year-old shrine that floats on the sea. By noon you are a thousand metres up, coaxing a flame out of cedar. At night you sleep in a quiet mountain valley. Sea and summit, prayer and fire, in one itinerary. Only in Hatsukaichi.
First night on the island. Second night in the forest.
From sea level to a thousand metres — begin here.
Archery, forest craft, ziplining, guided walks — bookable online.
For the travel trade
We work with tour operators and DMCs on the Sea to Summit itinerary — a night on Miyajima paired with one or two in the highlands. Product sheets, rates and FAM trip enquiries welcome.
Deep Miyajima
Once the day-trippers leave, Miyajima belongs to those who stayed. An island worshipped as a deity — cherished, we hope, for a thousand years more. Read the island's side of the story.
