Sony’s new handheld, the PlayStation Vita, is selling extremely poorly in Japan, and slowing down.

According to Andriasang, Sony shifted a meagre 8,250 PlayStation Vita units in Japan last week, down on an already alarmingly low 8,931 the week prior. Compare that to Nintendo’s 3DS handheld which sold 63,796 last week and 72,115 the week before. Even the older generation PSP is more popular than its successor, having sold 13,116 units last week.

Japan is traditionally a market that embraces new technologies faster than others. Sony Computer Entertainment New Zealand has declined Gameplanet’s request for local sales data.
