Interesting Fact

⚫🥚 At Owakudani, a volcanic valley near Mount Fuji, eggs are boiled in sulfur-rich hot springs until their shells turn completely black. According to local legend, eating one black egg adds seven years to your life. Many visitors happily line up to test their luck. 🎁 Bonus Kanji Fact The ancient form of 黒 originally represented a window or opening with smoke rising from a fire beneath it. As the smoke darkened the surface above, the character came to represent the color black itself.
