Are There any unique local food around Mt.Fuji?

Trying special local food is one of the most enjoyable things when we travel. Since Japan consists of islands spreading vertically from north to south, the condition of climate and geography has lots of diversity throughout the country. Thus almost any area in Japan has some local special products, dishes, or cooking styles.

Then, are there any "local special" food around Mt. Fuji? Of course there are several very famous local dishes as in Fuji-no-miya fried noodle, Yoshida Udon-noodle, and Houtou (a kind of thick Udon-noodle hot pot). However, today I'd like to introduce a local style grill we can find in this area.

The lower photos above were taken at a local restaurant near Kawaguchiko-Lake in Mt. Fuji area. The grilling way may not look special or different from usual grill, but actually the hot plates in the photos were made from a big lava rock from Mt.Fuji. This style of grill is called "Yougan Yaki (Lava Grill)" and there are several restaurants which provide "Lava Grill" dishes in the area.

Apparently lava rocks generate infrared when they are heated therefore they are good for grilling. I'm not sure if it scientifically true or not, but surely it is an interesting local food especially in the area around a volcano!
