Takunggu is a very famous sightseeing spot in Hakone area, is the remains of the crater formed by Hakone volcanic activity about 400,000 years ago, the air is filled with the smell of hydrogen sulfide rotten eggs, which is a very special landform. The black eggs in Oyonggu are famous, the eggs are steamed in hot springs, the eggshells turn black, and the name of the black eggs comes from this. There is a legend in Japan that eating a black egg can extend the life of 7 years. Of course, this is a beautiful legend. The egg in the Yuzi tea house is 500 yen, and there are 5 eggs in it. A bag of salt is included in the bag. The eggs are super fragrant when they are hot, and the salt is delicious. After all, eating one can extend the life of 7 years, and you must eat more! The store also intimately set up a small table where you can stand and peel eggs, so that everyone can eat while it is hot. There are many specialties in the Yuzi tea house, such as black mask, black bread dry, black jade chocolate, etc., bought Tang Xinzi fried cakes (a spicy seasoning) and black bread dry, the bread dry sweet crispy is very delicious, Tang Xinzi fried cakes are slightly spicy, open a pack of instant can not stop directly to the bottom (laughs) Their chocolate ice cream is also quite popular, this time I went late and didn't buy it, a little regrettable.
