The crunchy corn snack's producer, Yaokin, blamed the rising price of corn imported from the US for the hike, the first since Umaibo went on sale in 1979. Although the figures involved are tiny, the increase – less than 2c – is symbolically significant in "inflation-resistant" Japan, where firms have been reluctant to pass rising raw material costs on to consumers. Noriko Eda, a 59-year-old Tokyo resident, said she was "surprised" by the news. "Umaibo have been the same price for so long, so a ¥2 increase is a big deal." [...] Celebrity fans mourned the looming demise of the ¥10 price tag and, possibly, the loss of Umaibo's status as Japan's "national snack". "We're witnessing a turning point in history," tweeted rock musician Atsushi Osawa, whose band, Uchikubi Gokumon Doukoukai, referenced the snack and its "miracle" price in a 2010 song. "The price has started to diverge from the lyrics," he said.
