Japanese curry

I want to introduce about Japanese curry. Many Japanese like curry, so we often eat it. My friend’s family eats curry once a week. There are specialty stores of curry in Japan. This is “cocoIchibannya”. There are 1,186 stores in Japan and 44 stores in foreign countries. We can choose spicy levels, there are 12 levels. Also, we can choose what put on curry , for example eggs, natto, chicken cutlets, shrimps and so on. There are 40 toppings. These stores deliver to our home or office. Are there specialty of curry in Thailand?
