Wondering how to say I love you in Japanese after a few dates? Say suki desu rather than aishiteru: suki signals romantic interest, while aishiteru is typically reserved for serious, committed relationships.
The misunderstandings below are the ones that most often trip up learners who translate English directly. For broader habits that make phrases like these stick, see our guide on how to learn slang in a new language.
Why aishiteru is not the everyday phrase
The most common mistake is treating aishiteru as the Japanese twin of English “I love you.” Language Drops calls it the closest equivalent but notes it is not used as casually as in English, and that it is typically reserved for serious, committed relationships such as married couples or deeply devoted partners. Spirit Japan goes further: it is not commonly said, even between couples.
So is aishiteru too strong? It depends on the relationship. For early dating or casual affection it is too heavy. For a committed partner, once you are certain, it is the right word. Ling App reports that native speakers cautioned its author to use it only when 100% sure of their feelings. Busuu describes the related verb aisuru in similar terms, as a deep expression of emotion usually reserved for the most romantic or heartfelt moments of a person’s life.
| Phrase | Intensity and typical context | Planning use |
|---|---|---|
| Aishiteru | Closest equivalent to “I love you”, but less casual than in English; serious, committed relationships | Save it for a partner when you are certain; skip it on early dates. |
| Aishitemasu | Formal form; rarely heard in conversation, more common at weddings or similarly serious occasions | Recognise it when you hear it; you are unlikely to need it in conversation. |
| Daisuki | Stronger than suki; can mean “I really like you” or, playfully, “I love you a lot” | A warm, light-hearted step up once affection is established. |
| Suki desu / suki da | “Like”; used at the start of a relationship or for casual affection; desu is formal, da is informal | The safest default for a first confession. |
Figures and descriptions in this table draw on Language Drops and Ling App.
Read down the table and the pattern is clear: intensity rises from suki to daisuki to aishiteru, and formality is a separate dial.
What suki and daisuki really signal
Many learners assume “like” must be a downgrade. In practice, Busuu says suki translates best to “like” but is used in Japan to express that you are romantically interested in someone. Spirit Japan adds that the simple suki or dai suki is used more often than aishiteru. For a learner asking how to say I love you in Japanese in everyday life, those two words are the realistic answer.
- “Like” means lukewarm. Not in a romantic setting. Suki is often used at the beginning of a relationship, and Ling App says it is commonly used at a confession after a series of dates, with the third official date suggested as a typical moment.
- Daisuki is just a longer suki. It is formed by adding dai, meaning “big”, at the start to make daisuki desu, according to Busuu. Ling App calls it a whole lot stronger than merely saying suki, while Language Drops notes it can be playful and lighthearted.
- Saying “love” is the goal. Busuu points out that it is more common to say “I like you” or “I really like this” than to use a word for love. Choosing the milder phrase is not shyness; it is normal usage.
Politeness levels, pronunciation and writing
Adding politeness
Politeness is a separate choice from intensity. Ling App notes that most of these phrases are casual by default, and that adding the word desu makes them sound formal or polite. That is why suki desu is the formal confession and suki da the informal one among people who are close. Moving to the formal aishitemasu does not make aishiteru an everyday phrase, because that form is rarely heard in conversation.
Saying the phrases aloud
- Aishiteru: Ling App gives the pronunciation as aye-shee-teh-ru.
- Suki desu: Busuu gives skee dehs, so the u in suki is barely voiced.
Practise the whole phrase at an even pace instead of stressing single syllables, and check it against native audio.
Seeing it written
Spirit Japan says aishiteru can be written with the kanji characters for “love” and “to exist,” or with hiragana characters. Busuu notes that the Japanese symbol for love is technically the one for ai (愛). Hiragana spellings are common in casual messages, which suits a phrase that is casual by default.
Showing love without saying it
Another misunderstanding is that a partner who rarely says the words feels little. Language Drops observes that in Japan emotions are more often conveyed through actions than words. Ling App makes the same point about serious relationships: most people mainly demonstrate their love through actions instead of verbalizing it. Busuu also notes that a lot of Japanese is a little indirect, both out of politeness and just the structure of the language.
For learners, that changes how to read affection and how to give it:
- Read the gesture. Busuu lists small gifts and going out of your way to spend time with someone among the ways love is shown, and Language Drops says people often rely on actions or subtler expressions.
- Match words to actions. A modest phrase such as suki or daisuki, backed by a favor or time together, fits the way affection is usually expressed.
- Do not wait for the big word. If a partner never says aishiteru, that fits the general pattern and is not a sign of coldness.

Frequently asked questions
| Question | Answer |
|---|---|
| Do younger Japanese speakers say “I love you” more often? | According to Ling App, younger Japanese people are starting to say it more often, but they mainly use the casual form. |
| What is the difference between ai and koi? | Learning sites draw the line slightly differently. Busuu says koi as a noun refers specifically to romantic love, while ai is more about love in general. Ling App says ai refers to romantic love, while koi describes the feeling of being in love. |
| Should I use anata for “you” in a love line? | Usually not. Busuu says the pronoun anata is rarely used in regular speech, so a line that avoids it will sound more natural. |
| What do -chan and -kun add to a name? | They express closeness. Busuu says -chan is typically added to the end of girls’ names and -kun to boys’ names. |
