It's time to stop drinking with the boss after work.

That's the message of Mitsubishi UFJ Financial Group Inc. banking unit executive Saiko Nanri, who wants to change Japan's long-standing culture of drinks between managers and employees.

Companies have long encouraged such parties to give workers the chance to break down barriers with their bosses in an informal setting. Some see the alcohol-fueled bonding sessions as a way to relieve stress and advance their careers, while others feel obliged to attend. The practice is so ingrained that it sparked the term "nominication" — from "nomu," the verb for "to drink," and "communication."
