You step off the minivan at Shioya Station and the slope of Maruyama rises before you, a green shoulder meeting the blue of the Sea of Japan. The trail moves through mixed spruce and birch, switches into steeper fir-scented sections, then opens on ledges that frame Otaru’s rooftops and the distant cone of Mt. Yotei.

You step off the minivan at Shioya Station and the slope of Maruyama rises before you, a green shoulder meeting the blue of the Sea of Japan. The trail moves through mixed spruce and birch, switches into steeper fir-scented sections, then opens on ledges that frame Otaru’s rooftops and the distant cone of Mt. Yotei.
Geology here is recent—coastal terraces carved by rising and falling seas and volcanic soils drained toward the sea—so footing alternates between packed dirt and rocky steps. Culturally, the route skirts older fishing hamlets; look for weathered sea markers and simple shrines that signal local ties to both ocean and mountain. Guides often point out World War II-era coastal watch sites and the role these slopes played as common day-hike terrain for Otaru residents.
At the summit the sea dares you to linger: Yoichi, Otaru, and the distant silhouette of Yotei lay out like a living map while your guide pours a warming tea and hands out local snacks.
Practical guidance: the round-trip takes about four hours with moderate elevation change suitable for beginners with steady pace. Trails can be muddy in spring and slippery after rain, so carry traction-conscious shoes and bring 1–1.5 liters of water. Start mid-morning for stable weather and clearer views; summit snacks are provided but pack extra calories if you plan photos or slow sections. Transport from Shioya Station and hiking poles are typically included—confirm pickup time and weather cancellation policy before you go.
