Why N1 Exists

Some documents have no margin for "close enough".

JLPT N1 certifies the ability to handle complex, abstract Japanese. For a contract clause, a patent claim, or a safety-critical spec, an N1 translator is the difference between confidence and exposure.

Right nuance. Right intent. Right, with no margin.
