The morning chill causes mist to rise in the mountains, forming clouds that flow through the valley like silk

The “Sea of Clouds” is a spectacular natural phenomenon that occurs in the mountains of western Tokushima Prefecture. Here, the morning chill causes mist to rise in the mountains, forming fluffy clouds that flow through the valley like streams of silk. The best time to chase the Sea of Clouds is in the fall, and it is recommended that you set off as early as 5 a.m. to capture the iconic view. Weather is also a factor. Rainy days are no good, but the clouds do not always form even after a long stretch of sunny days. Local residents say you are most likely to witness the phenomenon following rain on a day forecast to be sunny. But even if you can’t catch the mists, you’re bound to see a gorgeous sunrise, so the view is always well worth the early wake-up call.
The Sea of Clouds is most often visible between October and early December, and the best views can be found at the Awashi Sea of Clouds Viewpoint, the Mine no Kubo Viewpoint, and the Shiozuka Highlands. Be sure to check the weather forecast in advance. Try to arrive at the viewpoint at least ten minutes before sunrise, and wear warm clothes, as it can be chilly in the early morning.
How to get there
From Shin-Osaka Station, take the JR Sanyo Shinkansen to Okayama Station, then take the JR Limited Express to Oboke Station (about 1 hour and 20 minutes). The Awashi Sea of Clouds Viewpoint is about 15 minutes by taxi or car from Oboke Station.
