If you have an interest in Japanese but can't commit to learning it, you can have a lot of fun by just learning Katakana (the alphabet used for foreign words like this). You see english words like this all the time, I used it multiple times a day there and it's a neat party trick to read them. I still catch lots of words in the wild even here in Aus.
Surprisingly useful if you travel there! Want some coffee? Well gosh, that's コヒ (kohi). Need a bathroom? Look for トイレ！(toire). Worth noting these are more than annotations, they are loan words and are part of the language in daily life.
It's easy to know if you are looking at katakana, and if it is you can expect to be able to sound it out to a foreign word, commonly english. It's very different stylistically to the other two scripts, hiragana and kanji. Much sharper, more masculine but still simple looking.(kanji) 漢字, (hiragana) ひらがな、 (katakana) カタカナ.
Katakana is also a useful skill in shopping situations. You can often confirm that a product is what you want by reading the katakana on it. This is helpful not only in Japanese stores, but some Chinese situations where Japanese products are popular (eg: health related products).
I always think of this as the dirty little secret of Japanese - that it includes so many English words "hidden" in katakana. If you learn katakana and walk around Tokyo you can probably read about 25% of the text ^_^
