Curry in retort food It is a rare blue-colored curry that was first released in Wakayama Prefecture. Yura Town is home to Shirasaki Marine Park, also known as the "Aegean Sea of Japan" I wanted to express a world view that matches the blue sea and blue sky that shine on the white rocky mountains. I made the curry blue. It is recommended for children and women because it uses soybean meat and has a sweet taste with nectar juice.
