What does it mean that this is a "Japan Spec" unit?
Honestly, I had to Google it. This is the answer I received:
"A "Japan spec" Nintendo Switch OLED means it's the version sold in Japan, primarily differing in its power adapter plug (Japanese Type A/B) and often defaulting to Japanese language, but it's still fully region-free, so it plays all worldwide game cartridges and eShop games; you might need a simple plug adapter for US outlets, but the console itself works globally, often with language settings easily changed".
