Exchanging Contact Details in Japanese

Asking socially

LINE is the default and the exchange is usually done by QR code, which removes the need to spell anything. The asking phrase is short and casual, and the moment for it is as the conversation is ending rather than in the middle.

Give a reason if there is one. Offering to send a photo, a restaurant recommendation, or event details makes the request concrete and easy to accept, which is why it is the most common shape.

The business card exchange

Meishi kōkan has a fixed choreography and it is worth doing correctly, because it happens in the first thirty seconds of a business relationship. Stand, present with both hands with the card facing the recipient, say your company and name as you offer it, receive with both hands, and read the card before setting it down.

The junior person offers first. If cards are exchanged simultaneously, offer with your right hand and receive with your left, then bring both hands to the received card. Keep cards on the table for the length of the meeting, arranged in seating order if there are several.

Asking how a name is read is a compliment rather than an embarrassment. It shows you intend to use the name correctly.

Apps, QR codes and the practical mechanics

Most exchanges now happen through a screen, and the vocabulary is short. LINE dominates socially, and work increasingly uses chat tools alongside email. The QR method removes the whole spelling problem, which is a genuine advantage for a foreign name.

Set your display name in a form that is recognisable. A profile with only a nickname in Latin script makes it hard for a new contact to place you a week later, which is a common reason contacts go unused.

The first message decides everything

An exchanged contact is not a relationship, and the message that follows is what determines whether it becomes one. Send it the same day, keep it to three lines, and refer to something specific from the conversation.

The specific reference is the whole technique. Anything generic reads as a mass message; one detail from the actual conversation shows you were paying attention and gives the other person something to reply to.

For business, send the follow-up email the same day or the next morning. It is the expected courtesy after a first meeting and its absence is noticed.

Keeping a contact from going cold

Japanese social contacts often go quiet not through disinterest but because neither side wants to be the one imposing. A light message with a reason, once every few weeks, is enough to keep a connection alive, and the reason can be very small.

Seasonal messages do this work efficiently. New Year greetings, a note when it turns cold, or a message about something you know they were doing all provide a reason to write without asking for anything.

Declining politely

You are allowed not to share, and there are graceful ways to do it. Offering a narrower channel, such as a work email instead of a personal app, declines the request while keeping the relationship intact.

A soft refusal with chotto and a trailing pause is also understood immediately and does not need explaining. As with any Japanese refusal, one is enough and it will not be pressed.

Reading the setting

Whether asking is appropriate depends almost entirely on the setting. A shared event, a mutual friend, a class or a hobby group all make an exchange ordinary. A service relationship, a large power difference, or a one-off encounter make it less so.

When unsure, offer rather than ask. Putting your own contact forward and letting the other person choose whether to reciprocate removes any pressure and is the safest form in an ambiguous situation.

Offering rather than asking is the general solution to every ambiguous row in this table. It costs nothing and puts the choice where it belongs.
