The long-term impact on Zensho’s shares will depend on whether the rodent incident leads to a significant fall in customers, the report quoted Shoichi Arisawa, an analyst at Iwai Cosmo Securities Co, as saying.
“I don’t think the incident reflects a structural problem with the business," he added. "But Sukiya can’t just dismiss it as a one-off accident.”
