    Between 1 & 2 (the highest two levels).  Although it's sometimes 
simpler than regular Japanese conversation because of the limited word & 
topic set you'll often need, and the ability to cut & paste many set 
phrases into letters, conversations, etc.  However, the ability to 
negotiate, discuss product specifics, etc. all require specialized 
knowledge of the product/industry and words required - thus, it's not 
quite the same as having even a Level 1 JLPT.
