What to know
Takeda Castle (Takedajō-seki) is a ruined hilltop fortress in Asago City, Hyogo Prefecture. It is often called the "castle floating in the sky" because on foggy autumn mornings it appears to drift on a sea of clouds.
Built in 1411, the castle later fell to Toyotomi Hideyoshi during his western campaigns to unify Japan. Its forces fought against the Tokugawa clan at the Battle of Sekigahara in 1600, and the castle was abandoned soon after. Over centuries it crumbled, until restoration work in the 1970s and 80s opened the site to tourists.
No original buildings remain, but the stone foundations are largely intact, revealing the castle's layout: a central fortress with three wings. Visitors follow a one-way walking course and enjoy panoramic views of the surrounding mountains and town below.
The best time to see the floating castle is in October and November around sunrise (6:00–6:30). On average, a sea of clouds appears one out of three mornings. The most popular viewing spot is Ritsuunkyo on the opposite mountain slope. You can drive to Ritsuunkyo's parking lot, then take a steep dirt trail with several observation decks. The lower decks are just steps away, but the best views are from viewpoints 1 and 2, a 10–40 minute hike. A 300 yen environmental cooperation fee is requested.
Takeda Castle lies halfway between the Seto Inland Sea and the Sea of Japan, about 70 km north of Himeji on the JR Bantan Line. The nearest station is Takeda Station at the foot of the hill. It is easiest to reach from Tokyo, Kyoto, or Osaka via the Tokaido/Sanyo Shinkansen to Himeji, then transfer to the JR Bantan Line.
The JR Bantan Line runs roughly one train per hour between Himeji and Takeda in each direction. The one-way trip requires a transfer at Teramae Station, takes about 90–110 minutes, costs 1,170 yen, and is fully covered by the Japan Rail Pass, JR Kansai Wide Pass, and JR Kansai Hiroshima Area Pass.
From Kinosaki Onsen, take the JR Sanin Line to Wadayama (55 minutes, 1–2 trains/hour) and transfer to the JR Bantan Line for Takeda (10 minutes, one train/hour). With good connections, the one-way journey takes about 80 minutes and costs 860 yen by local trains, or around 2,000–2,500 yen if using a limited express between Kinosaki Onsen and Wadayama. It is fully covered by the Japan Rail Pass, JR Kansai Wide Pass, and JR Kansai Hiroshima Area Pass.
Two steep nature trails lead from behind Takeda Station up to the castle. The strenuous ascent takes about 40 minutes and can be slippery after rain.
