In the final year of his incarceration, JD was sent to  a Mitsubishi copper mine in northern Japan.  There the old mine's conditions had  deterioated so badly, they made the physical site of the miracle-like, but  happily-avoided mine disaster in Chile pale in comparision.  
 There, because of Merritt's uncooperative attitude, he  was put to work on a detail led by the toughest Hancho in the mine, a sumo-sized  Japanese giant named Fukuda.  To "correct"  JD's  B.A., (bad attitude) he  was made to work alone in a basho no batsu. (an old, abandoned lateral nearing  collapse} When Fukuda accosted him one morning, JD's  Irish temper overcame his  good sense and he roughly cursed The Monster in fluent Japanese.  
 Dumfounded by JD's blasphemy, Fukuda screamed "Yattsukeru  omae no horyo." (roughly, "I'll kill you, slave.")   Then the man-mountain  charged  Merritt, his ridiculously short legs churning his body forward as his  long, gorilla-like arms swung like  blades on a windmill.  When JD glimpsed his  ham-like hands clenching, grasping and reaching, he knew this was a battle to  the death - no quarter given or expected.  Read the miracle-like ending in  "Adapt Or Die."
