For five years I have wanted to purchase the 3,000 Yen melon ($33.73 USD), but have not. On the way to Ōji Station across from Asakuyama Park an old man on a bike with white hair, a pink shirt, and a green sweater rode towards me. Signs are increasing in frequency. If he dyes his hair from white to black I will go to the market immediately. But there is a slight complication in that I have found a store in Shinjuku that sells 25,000 Yen melons ($281.07 USD), the new gold standard regardless of the bike rider's hair color. What signal will notify me when it is time to go shopping for expensive fruit in Shinjuku?
