TOKYO — Brendan White, a senior at Temple University’s Japan campus, says he has it all figured out. He is dressed in his “job hunt” black suit, accessorized with shiny leather shoes, a crisp white shirt — plain, no stripes and no wrinkles — and a black briefcase, for which he ponied up $20, just for this job-hunting season.

He also knows how to finesse his way into an interview room, Japanese style: You must knock three times, etiquette experts say — not once, not twice. Once in the room where interviewers are seated, “you close the door without turning away from the interviewers,” said Mr. White, a Massachusetts native. “You are not supposed to show your behind.”

Every move thereafter, including sitting down, should follow the interviewer’s cue, he noted.

All of this used to be a preserve for Japanese college students, who go through an arduous search process, lasting five to eight months, to land the job of their dreams. But, in a sign of changed times, a recent job fair in Tokyo, where Mr. White was scurrying around to meet officials at different corporate booths, was aimed exclusively at foreigners. Japanese companies are gearing up for an extensive international student recruitment campaign — a human resource strategy supporting a larger game plan to deploy their businesses more globally.

Isao Ogake, director of global career and education at Disco, a job fair organizer that hosted the international job bazaar in Tokyo, said corporate Japan’s appetite to engage more non-Japanese has been soaring, reflecting a growing desire to go global and to add diversity to the workforce.
