A flavorless candy appeared briefly in Japanese convenience stores and may never be sold again. We consider this news.

It had no taste by design. Even its name, Flavorless (?) Candy ¡ª yes, with a question mark ¡ª suggested more of an absence than a presence. But people in Japan are still talking about it, and in some cases missing it. That has given the product a sort of mystical allure.

The candy was manufactured by Kanro, one of Japan¡¯s major candy companies, and test-marketed in some stores last fall by Lawson, a convenience store chain. It appeared again for a few weeks this summer in most of the company¡¯s 14,600 stores.
