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.

At Bitchu Matsuyama Castle’s Sea of Clouds Observatory, a woman in a grey coat and pink scarf rests her arms on the wooden fence and looks toward the castle. The keep stands on the opposite mountain among autumn leaves, while white mist fills the valley between the mountains.

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.

With a sea of clouds and an autumn-covered mountain behind her, a woman in a grey coat pulls her pink scarf up over her mouth with both hands and smiles as her breath fogs the air. The dawn sky is pink and pale purple.

Takahashi before dawn

Before dawn in mid-November, a red convertible with its headlights on rounds a bend on a mountain road lined with autumn leaves. Below, lights from the town stretch along the river, with a bridge, white mist and stars in the sky.
Before dawn in November, I drove up the mountain road to see the sea of clouds. Down in the valley, the riverside town’s lights blurred through the mist.

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.
