In Japan, customers expect to find you on LINE

Email and Instagram are not where Japanese shoppers go to hear from a brand they like.

It is the everyday app. People use LINE for messages, bookings, coupons and repeat purchases, all in one place.
It is where brands stay in touch. Shoppers follow brands on LINE for restock news, offers and support.
It is the way back to a buyer. A brand that is not there loses the easiest way to bring a first-time buyer back.

What we do for overseas brands

Strategy, Japanese copywriting, design and setup sit with one team, so nothing is lost between a translator and a builder.

What LINE has done for our clients

Jewelry brand moving from wholesale to direct sales

12xmonthly retail revenue in three years, to 25 million yen

100%of live-commerce buyers became LINE friends

The problem. Sales came mainly from wholesale and stores. Few Instagram followers moved to LINE, and repeat purchases were low.

What we did. Rebuilt the LINE account with L Step, connected Instagram and live commerce to LINE, automated shipping and post-purchase messages, and ran point-based quizzes to keep customers engaged.

Weekly quiz and point program

Facial salon in Tokyo

900LINE friends in the first year, starting from zero

1.4xaverage spend per customer

1.6xmonthly cosmetics sales

The problem. Customer records and bookings were handled by hand, and the salon wanted existing customers to visit more often.

What we did. Moved customer records into LINE, automated messages before and after each visit, and sent two broadcasts a month with booking campaigns, a member's card, coupons and skincare recommendations matched to each customer's skin type.

Booking campaign and member's card

Global electronics brand entering Japan

15,000new LINE friends in one three-month campaign (approx.)

551verified purchase applications

70customer inquiries handled in Japanese (approx.)

The problem. The brand wanted to step up its marketing in Japan but had no LINE know-how. It needed a partner who could start by proposing the campaigns and ads that bring people to LINE.

What we did. Proposed the campaigns and ads, managed the LINE Official Account, built purchase campaigns inside LINE with L Step, and ran the campaign support desk.
