Why Does Official LINE Increase Sales? 5 Reasons You Should Start Right Now

The reasons why Official LINE increases sales and why you should start right now are as follows.

I will explain each one!

1. LINE is the most used SNS in Japan, so its reach is overwhelming

The number of monthly users is 97 million (as of March 2025). In other words, it is calculated that more than 70% of Japan's population uses it. This is overwhelming compared to Instagram or X (formerly Twitter).

Moreover, unlike other SNS, LINE is characterized by the fact that "notifications are always checked."

If you get them to register as a friend, messages are highly likely to be seen, and the open rate is said to be as high as60-80%.

In other words, LINE messages have a higher probability of being seen than flyers or direct mail.

Even without running ads, you can build a list in-house andconnect with those people repeatedly.

This alone is a huge opportunity to increase sales.

2. You can automate "prospect education" and "trust building"

Official LINE has features that allow for so-called "scenario design," such as "step messaging" and "auto-responses."

By utilizing these, you can automatically build a flow like the one below.

In this way, even without a sales representative talking to each person individually, you canautomatically designthe flow of "education to trust building to purchase."

In fact, one beauty salon introduced this step messaging and achieved:

• Increased reservation rates by resolving pre-visit anxiety

• A 30% increase in repeat rates through careful follow-up after the visit

resulting in total sales reaching 160% compared to the previous year.

3. Send sale information and event announcements instantly with mass messaging

Unlike email, LINE's "mass messaging" has a high delivery rate and is real-time.

For example,

• Sales starting tomorrow

• Announcements of reservation slots that suddenly opened up

• Advance reservation information for new products

It is also effective for attracting customers where speed is required.

L-Stepcan also be used to specify more detailed conditions for "segmented messaging." For example,

• People who have not visited in over 30 days

• People who have purchased products before

• People who answered 'interested' in a survey

By segmenting based on conditions like these and delivering messages tailored to each, you can achieve a higher response rate.

4. Deepens relationships with customers, leading to repeat business

The strength of LINE is that it allows for one-on-one communication.

By utilizing the chat function in addition to message delivery, you can smoothly handle individual consultations and inquiries.

Furthermore, by utilizing rich menus, coupons, and stamp cards, you can provide a system that makes customers think, 'I want to go again' or 'I want to buy again'.

For example, at one hair salon,

• introduced a LINE-exclusive stamp card (free treatment after 5 visits)

• easily accepted next appointments via chat

As a result, communication with customers became smoother, and the repeat rate improved significantly.

5. Cost-effectiveness: You can start with zero initial cost and no monthly fees

In fact, you can start an Official LINE account with a free monthly plan (as of 2025).

• Initial cost: 0 yen

• Monthly fee: 0 yen and up (paid plans depend on the number of friends and messages sent)

In other words, there is no cost to start, so you can 'try it out' first.

Moreover, the setup is relatively easy. You can open an account with just a smartphone, and the management screen is intuitive, so even beginners can feel at ease.

For those who are 'anxious about spending tens of thousands of yen on advertising right away,' highly cost-effective Official LINE is the perfect way to take the first step in attracting customers.

FAQ (Frequently Asked Questions)

Q1. How long does it take to open an Official LINE account?

A. It can be set up in as little as 5 minutes.
If you have a computer or smartphone, you can create it for free from the LINE Official Account management screen.

Initial setup is also easy if you follow the guide.

Q2. Is it difficult to operate without specialized knowledge?

A. It is not difficult.
Basic operations are designed to be intuitive, and step-by-step messaging and rich menus can be easily set up using templates.

Q3. What makes it superior to other social media or email newsletters?

A. Its "high open rate" and "two-way communication."

Because LINE notifications arrive in near real-time, the open rate is extremely high at 60-80%, and since one-on-one chat support is possible, it is well-suited for building relationships with customers.

Q4. Is there any point for small businesses or individuals to introduce it?

A. Absolutely.
In fact, even if the sales scale is small, the effect of an Official LINE account is immense for businesses where repeat customers and customer management are important. The appeal is being able to create a "sales-generating mechanism" without spending money.

Q5. How should I increase friends (followers)?

A. It is common to utilize in-store POP displays, social media, and QR codes.
Running campaigns or offering coupons with benefits will naturally increase your registration rate.

Since the design of the registration flow is key, getting professional advice is also recommended.

Now is the time to acquire a "sales-generating mechanism" with an Official LINE account

As introduced so far,

• Overwhelming reach

• Automation of education and trust building

• Mass messaging with high delivery rates

• Relationship building that leads to repeat business

Based on these 5 reasons, I recommend that you introduce an Official LINE account right now.

In fact, many of my clients have told me things like,
"My monthly sales have stabilized since I introduced Official LINE"
and
"I've increased repeat customers without spending money on advertising."
