The sightseeing center above Oyonggu, Yuzi Tea House, has a lot of hands for sale and the products are very rich. Since Oyonggu is the hottest attraction in Hakone, there are many tourists, and the densest is this place, crowded with people. I looked around a little and left. There are black eggs selling the most distinctive local characteristics at the door, 500 /5. Basically no queue, the action is very fast. The packaging is good, and I ate two on the spot. Anyway, this black egg is very good for the body, it is the practice of boiling eggs, because the local environment egg is boiled outside is all black, the inside is boiled eggs, the eggs are still quite fragrant.
