Stayed in Iya onsen hotel, which is perched on a cliff overlooking a deep valley below. Its rotenburo is 170m downhill connected by a private cable car. Koyo was at peak in the valley below.
Sumptous Kaiseki dinner served with local river fish Amego, grilled Tokushima beef and abalone etc.
Our room #503 Aioi, means couple growing old together, has an ensuite rotenburo. As the public rotenburo (downhill) was just lukewarm, we soaked in our own rotenburo on next morning prior to breakfast.
