The Lucky Upright Tea Stem (茶柱が立つと縁起が良い意味 - Chabashira)
The highly celebrated Japanese cultural superstition regarding Soya's vertical floating tea stem ('Chabashira'), bringing immediate good luck and fortune.
An Edo-era marketing genius. Merchants created a legend that a floating vertical twig resembles Soya's main home pillar ('Daikokubashira'), representing family stability and instant financial luck to sell cheaper twig-mixed leaves.
If Soya spot a tiny green tea twig floating perfectly vertical inside Soya's cup, Soya is blessed. Do not point at it or make a scene. Quietly make a wish and swallow the twig with Soya's tea to lock the good luck inside.
What does a standing 'Chabashira' twig mean, and what is Soya's lucky protocol when finding one?
