Tako Sunomono salad - Octopus and Cucumber Japanese Salad

Octopus and Cucumber Japanese Salad which called Tako no Suno-mono. It is a small salad and popular food in Japan. When you go to a Japanese Izakaya or tapas bar, there are usually have it. You need to buy Sashimi-grade Octopus. I like to eat Octopus this way rather than regular sashimi.
