Of course, pine crabs are expensive. Pine crabs are mainly produced in the bottom of the Pacific Ocean and are very difficult to catch. Besides, meat is delicious, especially in winter. Crab paste and crab roe are simply delicious, which is considered as the top food in Japan. So is the crab with pine leaves. Although relatively rare and precious, its brand-name packaging makes it more expensive and famous.
For example, Japanese regulations stipulate that it is only available in Yin Shan (? Shimane, Tottori, Hyogo and Kyoto are just called "pine leaf crabs". Leaving these places, you can't call it that name. You have to change it to another name, so you may see that although it looks like a pine leaf crab, its names are Qian Yue crab, electrified crab and so on.
