LINE reaches more than 100 million monthly active users in Japan — the country's strongest channel for loyalty and repurchase. Next Level runs LINE end to end in Japan, with bilingual reporting throughout. For the strategy layer, read our guide: LINE for Luxury & Fashion Brands in Japan.
We build and run your Official Account: profile, rich menu, greeting and auto-reply flows, broadcast planning. Japanese copywriters produce every message, adapted from your global assets or created locally. GA4 and GTM integration ties LINE into your analytics from day one.
Since February 2026, LINE Ads runs inside LY Ads — the unified platform combining LINE and Yahoo! Japan inventory. Our strategists run cost-per-friend (CPF) campaigns across both networks.
Once your base reaches critical mass, broadcasts drive loyalty and store visits.
Every Mini-App interaction returns the customer’s LINE uID — the persistent identifier behind segmentation and 1-to-1 messaging. We build LIFF-based Mini-Apps that open inside LINE with no install: registration, booking, in-store check-in. Each uID goes into the CRM of your choice, ready for segmentation, triggered flows, and revenue attribution.
LINE Hub, our proprietary marketing platform built on the Messaging API, adds what the standard account manager lacks: audience segmentation, automated messaging scenarios, and multi-tab rich menus.
We configure the Official Account’s built-in chat for a single boutique, or connect external chat tools for multi-store operations — one inbox for store associates, full history attached to each customer’s uID.
Our dashboards analyze LINE OA and LY Ads metrics alongside the KPIs that decide account health: open rate, block rate, click rate, and message timing. Reporting comes in Japanese and English, so global headquarters and the Japan team read the same numbers.
What is Next Level LINE Hub? Next Level’s proprietary marketing platform on the LINE Messaging API: audience segmentation, messaging automation, and multi-tab rich menus.
How long does it take to launch a LINE Official Account? Verified account screening takes two to four weeks (estimate). The full setup is usually live within the first month.
Which CRM platforms can LINE connect to? Any system with an API — Salesforce, HubSpot, Klaviyo, and others. The link runs on the LINE uID, collected via the Messaging API and Mini-Apps.
Do you have case studies on luxury LINE accounts? Yes. Repossi gained 18,000 LINE friends in the first year after launch, block rate held low, reporting in three languages — read the case study.
Can we run LINE without a physical store in Japan? Yes. Segmented broadcasts, Mini-Apps, and CRM sync all work for online-only brands; stores add an O2O layer.
