転向(てんこう)

do an about-face ★★★☆☆ CCW
(roll over) + (turn to face) = 転向 (do an about-face)

convert to new ideology, do an about-face. This is important because most of the freaky looking kids you see on the street will all become housewives and salarimen the exact second they turn 23. - making TENKOU what we call a "cultural code word."

転勤(てんきん)

transfer ☆☆☆☆☆
(roll over) + (be employed at) = 転勤 (transfer)

when a salariman gets transferred to another office, that's tenkin.

I only mention this because most of the Japanese you meet who speak good English, probably one of their parents got tenkin-ed to America / UK, so it tends to come up in conversation.
