At the time when he turned twenty-three he came to suffer from a bad headache.
Though he consulted a doctor, the doctor could not find out what the cause of headache was.

Kaneo Kohara said:
"He often complained of a headache.  Looking back on it now, I think he was filled with frustration and was suffering from neurosis. He probably was caught in a dilemma of choosing about his career advancement.  In the meantime, someone advised him to switch his job and he jumped at the advice.

He quitted the ironworks and got a job at a seafood shop at Kanasugi, Tokyo. It seemed that he did an about-face in his career.  In addition to tending the shop, his job included buying from a fish market and going the rounds of customers.

Oddly enough, his headache vanished.  He worked there diligently until he met Old Jack Frost.
