Mt. Shiraiwa Forest Trail (Kobayashi)

The Mt. Shiraiwa forest trail starts near Shiraiwa in Kobayashi City, about 70 minutes by car from Miyazaki City, or reachable via Kobayashi Station followed by a 20-minute taxi ride; no permit is required. The 5 km loop climbs about 200m from the trailhead to the 850m summit and takes roughly 2 hours at a steady pace. The path is packed dirt through forest for most of its length, well-marked and shaded by tree cover, with no technical sections or significant exposure; a short, slightly steeper stretch near the summit is the only notable change in gradient. The main landmark is the summit clearing itself, which opens onto views across the Kobayashi basin and, on clear days, toward the Kirishima range, making it the natural high point and turn-around before the loop descends back through the forest. There are no water sources or shelters along the route, so the modest 1L recommendation for water is generally sufficient given the trail's short length and shade cover.
