How to Say Date of Birth in Japanese: Formal and Informal Ways

Learning how to say “date of birth” in Japanese can be useful in various situations, whether you’re visiting Japan or just looking to expand your language skills. In this guide, we’ll explore both the formal and informal ways to express this phrase in Japanese. Additionally, we’ll provide useful tips, examples, and address regional variations if necessary.

Formal Ways to Say Date of Birth in Japanese

In formal settings, it’s important to use appropriate language and honorifics. Here are some phrases you can use to state your date of birth formally:

1. Tanjoubi – This is the most commonly used term, which translates to “birthday.” The formal full phrase is “Tanjoubi wa nan-nen- nan-gatsu-nan-nichi desu ka,” where “nan” represents the day, month, or year you are specifying.

2. Seinen gappi – “Seinen” means “birthdate,” and “gappi” translates to “when” or “which day.” So, this phrase directly asks for someone’s birthdate in a formal manner. For example, you can ask “Seinen gappi wa nan-nen- nan-gatsu-nan-nichi desu ka?” to inquire about someone’s birthdate.

Note that in both formal phrases, it’s crucial to replace “nan” with the specific day, month, or year you want to mention. This specificity adds clarity and precision to your question or statement.

Informal Ways to Say Date of Birth in Japanese

When talking casually with friends or peers, you can use more relaxed language. Here are a couple of informal phrases to express “date of birth” in Japanese:

1. Tanjoubi – Just like in formal situations, “tanjoubi” can also be used casually. You can directly mention the specific day, month, or year, such as “Watashi no tanjoubi wa nan-nen- nan-gatsu-nan-nichi da yo,” which means “My birthday is on…”.

2. Gappi – “Gappi” is a casual abbreviation of the formal phrase “seinen gappi.” It is commonly used when conversing with friends and peers. Using this term, you can ask questions like “Gappi wa itsu?” to ask “When is your birthdate?” informally.

These informal expressions are best suited for friendly conversations or when interacting with people you are close to. Remember to adjust your language based on the level of formality appropriate for the situation.

Regional Variations

While the formal and informal phrases mentioned previously are widely understood throughout Japan, it’s important to note that regional variations exist as well. Here is an example of a regional variation:

1. Tanjoubi omedetou – In some areas of Japan, instead of mentioning “tanjoubi” or “seinen gappi,” people will often express “happy birthday” with “tanjoubi omedetou.” Although this phrase does not directly mean “date of birth,” it is commonly used to congratulate and wish someone a happy birthday.

Remember that regional variations can sometimes lead to differences in vocabulary and expressions, so it’s always helpful to familiarize yourself with the local customs and language norms of the specific region you are in.

Tips for Using Date of Birth in Japanese

Here are some tips to help you effectively use the phrases discussed above:

1. Be mindful of politeness: When communicating in Japanese, it’s important to consider the level of politeness necessary for the situation. Using formal language with strangers or in professional settings is generally considered the safest approach.
2. Practice pronunciation: Japanese pronunciation can be challenging for beginners. Make sure to listen to native speakers and practice repeating the phrases until you feel comfortable with the correct pronunciation.
3. Use appropriate body language: When speaking Japanese, body language and gestures can greatly enhance communication. Showing respect by bowing slightly or maintaining a friendly demeanor can help create a positive impression.
