You Already Know a Lot of These
Japanese borrows heavily from English, and those loanwords are written in katakana. That means a beginner who has just learned the katakana syllabary can already read — and often understand — a surprising amount of real-world Japanese signage, menus and packaging.
The catch is that the pronunciation has been reshaped to fit Japanese sound patterns, and some meanings have drifted. Learn the patterns, and the vocabulary arrives almost free.
Three sound habits to expect
Consonant clusters get broken up with vowels (strike → ストライク), final consonants often gain a vowel (cake → ケーキ), and l/r sounds map onto the Japanese r row (hotel → ホテル).
Food and Drink
Technology
Note パソコン: a contraction of personal computer that no longer sounds like English at all. Loanwords regularly shorten — smartphone becomes スマホ, convenience store becomes コンビニ.
Places and Transport
Clothes
Sport and Leisure
カラオケ and アニメ are Japanese coinages that have travelled back into English — useful reminders that loanwords can be bidirectional.

Where Meanings Drift
Some loanwords look like English but mean something narrower or different. These are the ones that cause misunderstandings.
Read it aloud
When you meet an unfamiliar katakana word, read it aloud and listen to yourself. Most of the time the English original appears, sometimes after a syllable or two of adjustment.
How to Practise
Katakana is best learned from the world rather than a list: menus, packaging, shop signs and app interfaces. Photograph signage and decode it later, and say each word aloud so the sound-to-meaning link actually forms.
If you are still mastering the syllabary itself, start with learn hiragana and katakana, then move on to sentence structure so you can use these words in sentences.
FAQ
Why are English words written in katakana?
Katakana is the script for foreign loanwords, onomatopoeia, emphasis and some brand names. Words borrowed from English are conventionally written in katakana, which is why katakana knowledge unlocks so much vocabulary so quickly.
Do Japanese people understand English loanwords spoken in English?
Often not immediately, because the Japanese pronunciation is adapted to Japanese sounds. コーヒー is understood as coffee, but saying "coffee" in English may not be recognised as quickly as the katakana pronunciation.
How many katakana loanwords are there?
Thousands are in everyday use, and new ones appear constantly. The hundred here are the highest-frequency core — enough to read menus, packaging, signage and app interfaces with reasonable confidence.
Why does ケーキ have a long vowel?
Because Japanese syllables usually end in a vowel, so the final consonant of "cake" is resolved by adding one. The macron-like ー marks a long vowel, matching the pronunciation of the English word.
