Bitchu Matsuyama Castle Sea of Clouds Observatory Two alarms, one castle above the mist
In photos of the sea of clouds, the castle looked as if it were floating alone above a blanket of white mist. I wanted to see it for myself. I was curious what the mountain looked like on a clear day, too. So I drove to Takahashi 4 times in different seasons. The Sea of Clouds Observatory gives you a view of Bitchu Matsuyama Castle on Komatsu-yama from the ridge opposite. The keep stands 430m above sea level. It’s about 15 minutes by car from Kayo IC.
In 4 visits, I saw a sea of clouds just once. Even so, each time I stood on that same deck, something different caught my eye.
SpringMay
I’d memorised all 4 peak names, but…
A 1-night trip to Okayama in May. The day before, I drove from Tokyo along the expressway in my red convertible and stayed in Okayama City. At the inn, I practised saying the name of the mountain with the castle out loud. Gagyūzan is the name given to a group of 4 peaks: Ōmatsu-yama, Tenjin no Maru, Komatsu-yama and Mae-yama. The castle keep stands on Komatsu-yama. I’d only seen the observatory in photos of the sea of clouds, and I wanted to see what it looked like under fresh green leaves, without the mist.
The next morning, on the way to the observatory, I spotted a blue Route 484 sign. 4, 8, 4. The numbers lined up so neatly that I caught myself saying, “That’s a nice number.” I couldn’t take a photo, but I memorised the sequence. From there, I followed the signs up the mountain road. The bends kept coming, so I slowed down early and looked ahead to each exit. With the top down, I climbed slowly beneath the fresh green canopy. The smell of new leaves drifted through the car.
I arrived at around 9 am. There’s room for only about 4 cars by the observatory, so I parked in the larger car park about 200m farther along and walked back to the entrance. The morning air was still chilly, and I was glad I’d worn my hoodie. The deck, built on log pillars, suddenly came into view through the trees. I’d come to see the castle, but the first things I looked up at were the steps and the little roof. I rested my left hand on the rail and placed my white sneaker on the first step. I kept my phone in my right hand, but lowered it. First, I wanted to see everything for myself.
The wooden deck has 2 levels. When I stepped onto the upper one, a tiny roof sat above the trees on the opposite mountain. “There it is!” I said—but then came the tricky part. I’d studied those 4 peak names so carefully the night before, but from here I couldn’t tell where one ended and the next began. Fresh bright leaves and deeper green trees spread in patches, and the ridgeline looked like one long, unbroken wave.
I stopped and thought it through. The keep was on Komatsu-yama. So the mountain with that little roof on top had to be Komatsu-yama. Using it as my landmark, I traced the ridge with my finger at the log fence and counted each rise, one by one. Maybe this one, maybe that one. There was no one to tell me if I was right, but as I followed the line with my fingertip, the ridges I’d thought of as one long mountain range began to look like separate peaks.
The roof looked so tiny in my phone photo. I had to zoom in just to make out its shape. But I’d found it myself, so I wanted to keep a photo of it. One day, I’ll climb up to the castle and see if my guess was right from beneath that roof.
On my way back, I drove down to Takahashi and bought yubeshi at Tennindō in Higashimachi. They say Takahashi yubeshi began as a sweet presented to Lord Katsutsune Itakura, the 6th-generation lord of Matsuyama Domain. Thinking this was once a treat for the lord of the castle I’d just been admiring made me handle the packet a little more carefully. Back in the car, I opened the wrapper made of washi paper, and the scent of yuzu filled the cabin. The chewy cake was mildly sweet, and the yuzu aroma lingered after each bite. I reached for another, then another, and before I knew it, I was opening my third packet in the driver’s seat.
SummerAugust
I looked down on the town the mist had hidden
I kept wondering what lay beneath that white mist on mornings with a sea of clouds. The question stuck with me every time I saw a photo, so I decided to find out in summer, when there wouldn’t be any mist. It was the second day of my 2-night trip to Okayama in August. At around 10 am, I drove up the mountain road from Kayo IC—about 15 minutes away—in my convertible with the top down. Then the wooden steps and the grove beside them came into view.
The moment I got out of the car, the summer air clung to my arms. I’d come in a white tank top and khaki cargo miniskirt, and I was still hot. In the shade at the foot of the steps, I took a sip of water and looked up along the handrail to see how far I had to climb. The woods were full of cicadas. It felt like a completely different place from the quiet spring morning.
The deck has 2 levels, so I compared the view from the lower and upper ones. Just a slight change in eye level changed how the foreground trees overlapped with the castle keep. I went up and down the steps over and over, looking for the clearest view. I wanted to check my spring guess, too, but the summer leaves were thicker, so it was even harder to tell where one peak ended and another began.
I lowered my gaze and caught my breath. The Takahashi River ran below the deck, with the rooftops of Takahashi stretching along its banks. In photos of the sea of clouds, this whole view is hidden beneath the white mist. From up here, a sea of clouds looks like a dream—but for the people in town, is it just a misty morning? Somewhere in town, someone might be eating breakfast under one of those rooftops. Someone else might be heading to work along a road where the fog hides whatever lies ahead. Thinking of that made the photos of the sea of clouds look a little different to me.
Bitchu Matsuyama Castle is the only mountain castle among Japan’s 12 castles with original keeps still standing. When I looked at that little roof across the way, I couldn’t stop wondering how they’d carried stone and timber all the way up there. How many trips did that take, hauling it all on their shoulders? By the time I’d thought it through, the mountain road I’d driven up seemed incredibly easy by comparison.
I took a photo of the roof, then retook it in portrait orientation to include the river and the town. Castle at the top, river and town below. If I took the same photo on a morning with a sea of clouds, the mist would fill the lower half of the frame. I decided to save this one for my autumn comparison.
Looking down at the riverside road from the deck made me want to drive it myself. I went down the mountain and followed the Takahashi River. The rooftops I’d just seen from above passed by my window in the same order. It felt like driving through a map I’d just seen from above. A breeze from the river drifted into the open car, and I turned the music down a little.
For lunch, I ordered Bitchu Takahashi Indian Tomato Yakisoba in town. It’s a local fried-noodle dish with curry flavour and Takahashi’s specialty tomatoes. The tomato’s tartness cut through the curry and cleared my head, which had gone fuzzy in the heat. By the time I finished my plate, I’d stopped sweating. I’d already bought yubeshi in spring, so I was only going to drive past today—but before I knew it, I was turning the wheel toward Higashimachi.
AutumnMid-November
Each time the mist shifted, the lower part of the castle keep appeared and disappeared
I set 2 alarms. By the time the first one rang, my eyes were already open. It was mid-November, and I’d booked a room in Takahashi, close to the observatory, for a 1-night trip so I could catch the sea of clouds at dawn. The night before, I checked the forecast over and over. They say a sea of clouds is more likely when the skies are clear, there’s no wind, and the difference between morning and midday temperatures is large. The forecast called for clear skies and light winds. All I could do now was leave it to the mountain.
It was still pitch-black as I drove about 20 minutes from the area around Bitchu-Takahashi Station to the observatory. The headlights of my red convertible swept across the autumn-coloured slopes, one bend at a time. There wasn’t a single oncoming car. The mountain road was dark, so I drove even more carefully than usual. In the mirror, the lights of the riverside town glimmered through mist in the valley below. I hoped that mist would climb all the way up to us.
I parked in the observatory car park, fastened my grey coat and adjusted my pink scarf. Two people with tripods were already on the deck. I bowed and said a quiet “Good morning.” An older man pointed toward the opposite mountain with his chin. “There’s a sea of clouds this morning,” he said.
I rested my arms on the log fence and looked where he’d pointed. The gap between the mountains was all white. Above that white sea, a little roof floated, surrounded by autumn leaves. I’d seen that scene in photos countless times, but in person it was completely silent. I forgot to breathe and stood frozen for a while.
The mist looked still, but it was moving slowly. The lower part of the castle appeared for a moment, then disappeared under the white again. Each time, I leaned on the fence and compared how much more I could see. Knowing the view would disappear when the mist cleared, I couldn’t bear to take out my phone just yet. First, I wanted to take it in with my own eyes.
The castle I was looking at stands on Komatsu-yama, 430m above sea level, and this observatory is on a different peak. That’s why the castle looks as if it’s floating above the mist when you see it from here. The ridgeline I’d traced with my finger in spring was almost all hidden now, with only its highest part rising above the clouds. The river and town in the bottom half of the portrait photo I’d taken in summer had vanished beneath a white sea. Just as I’d expected—and still, I could hardly believe it.
The sky shifted from pale purple to pink, and the morning light spread across the clouds. The autumn leaves on the castle mountain slowly emerged from the white mist. The tip of my nose was cold, so I pulled my scarf up over my mouth with both hands. My breath escaped through the gap in the fabric. I gave myself a little credit for getting up after setting 2 alarms.
As I was leaving, I bowed to the man and thanked him. Then the end of my scarf caught on the fence and nearly came loose. So much for a graceful exit. By the time the mist thinned and the foot of the mountain came into view, I was back at the car park. Thanks to the early start, I still had the whole day ahead of me.
WinterEarly December
Through the bare branches, I made out the keep and the two-storey turret
The season for thick morning mist lasts until early December. I figured this might be my last chance to catch it this year, and that made me want to go one more time. I took a red 4WD sedan in case there was snow on the roads. I drove from Tokyo to Okayama and stayed in Takahashi for both nights.
On the second day, the mountain road was still dim at dawn, and the surface was slightly damp. The 4WD responded smoothly to every turn of the wheel. Even so, I didn’t hurry. I slowed a little before each bend, watched the road ahead in my headlights, then gently pressed the accelerator again. I like driving on mornings like this. I can feel my breathing and the car’s movement gradually falling into step.
At around 7 am, I stepped onto the deck. The mist wasn’t as thick as it had been on the autumn visit. It had only pooled in white patches in the valley—not enough to call it a sea of clouds. Honestly, my shoulders sank. I held the thermos of hot tea I’d brought from the inn against my ivory coat with both hands, letting its warmth through my gloves steady me as I looked toward the opposite mountain.
Then I noticed: a large roof on the left, and another, smaller one to its right. The castle keep and the two-storey turret. Last autumn, I’d only found one roof. Maybe the leaves had fallen, leaving a gap in the branches for the second one to peek through. The thin mist and bare trees should have been disappointing, but they’d shown me something new. I gently clenched my hand into a fist inside my glove.
When I looked for the roofs through the branches, shifting half a step made them appear and disappear behind the branches. I went back and forth across the deck, searching for the clearest view. It was cold enough that my breath turned white, and I kept tightening my grip on the thermos. Still, I’d decided I wasn’t leaving until I found the spot where the 2 roofs lined up just right.
As the morning sun reached the upper slopes of the opposite mountain, the trees it touched began to stand out. The edge between the valley mist and the hillside grew clearer, until I could make out the bumps and hollows I hadn’t seen before. In spring, I tried to sort out the names of the peaks; in summer, I looked down at the town beneath the mist; in autumn, I watched a roof float above the sea of clouds. On my fourth visit, there were 2 roofs. I’d stood on the same deck 4 times, and each time I took something different home with me.
When the mist thinned, I went back to the car and turned on the heater. Once I could move my fingers inside my gloves again, I looked through my photos. I’d managed to get one with the keep and the two-storey turret side by side. I’d barely touched the tea in my thermos. I decided to buy yubeshi in town on the way back and have it with hot tea at the inn, then started down the mountain road.

Local treats to try on your trip
Takahashi yubeshi
A mochi sweet made with local yuzu. In Takahashi, you’ll find wrapped yubeshi shaped like narrow rectangles, as well as sliced yubeshi. One spring, I opened a washi-paper wrapper in the car, and the yuzu scent got the better of me—I ate 3 in a row.
Bitchu Takahashi Indian Tomato Yakisoba
A local Takahashi dish of curry-flavoured yakisoba topped with the area’s specialty tomatoes. I had it for lunch on a hot summer day, and the tomato’s tartness snapped me back to attention.
Highlights
A morning when the roofs float above the mist
On a morning with a sea of clouds, only the upper part of Komatsu-yama, at 430m above sea level, rises above the mist, making the castle roof look as if it’s floating. The observatory is on another peak, so you can see the castle above the clouds from the side. The mist never stands still; it shifts to reveal the lower part of the castle, then hides it again.
The only mountain castle with its original keep still standing
Bitchu Matsuyama Castle is the only mountain castle among Japan’s 12 castles with original keeps still standing. Its mountaintop setting is what lets you see it floating above the mist.
