ELI5:Why are there so many English words in Japan?

Watching a video of the New 3DS review recently, the guy had a Japanese model.  In the shortcut settings, there's a setting to turn Wireless and NFC on/off.

On his version the option was called ワイヤレスのための/NFC (no idea if that Japanese is correct, but it'll do for an example).

My questions is why is it labelled <some Japanese text>/NFC (where NFC is in English)? Why not <Japanese word for wireless>/<Japanese word for NFC>?

And now I think about this, I've seen loads of other examples on TV, etc, over the years.

Why do English speakers use the words schadenfreude (German), hors d'oeuvre (French), piñata (Spanish), al fresco (Italian), in absentia (Latin) and karaoke (Japanese)? Because often different languages will have words that don't have direct translations, and in those cases it's common to just "borrow" the word as is.

In technology, it would be more common for other languages to "borrow" English words/phrases as the most commonly used international language in technology industries is English. **N**ear **F**ield **C**ommunication probably doesn't have an existing direct translation in Japanese, and people who would even know what it is can probably read some basic English, so they've kept it as an English acronym.
