Is ラップトップ the same as ノートパソコン? Do Japanese people even say ラップトップ?

Rei

They refer to the same device, but ノートパソコン (or ノーパソ for short) is the standard everyday word in Japan. ラップトップ is understood but rarely used in natural conversation — it sounds like translating from English!

What Is ノートパソコン?

ノートパソコン is the standard Japanese term for a laptop computer. It combines ノート (note/notebook) + パソコン (personal computer). The “notebook” image comes from the clamshell design resembling a notebook. パソコン itself is short for パーソナルコンピュータ (personal computer).

• ノートパソコンを持ち歩く。 — To carry a laptop around.
• 新しいノートパソコンを買った。 — I bought a new laptop.
• ノートパソコンのバッテリーが切れた。 — My laptop battery ran out.
• ノーパソ、貸して！ — Lend me your laptop! (casual)

What About ラップトップ?
