Since the LY Corporation merger, LINE and Yahoo! Japan inventory live inside a single advertising ecosystem — the most powerful Japanese consumer reach available to a foreign brand. Deebo is an active LY Corp partner agency. We run the messaging, the search, the display, and the Smart News supply as one engine.
LINE has 97 million monthly active users in Japan — a national infrastructure layer for messaging, payments, news, and increasingly for buying. Yahoo! Japan remains the dominant Japanese portal, search engine, and Q&A community. The 2023 LY Corporation merger collapsed both into one ad stack: a single buying platform, shared first-party data, and a unified set of audience products. Foreign brands underweight both because they're invisible from outside Japan; we operate them as the foundation of every serious Japanese growth plan.
"Japanese consumers don't switch between apps. They switch between rooms inside LINE. The brands that understand this win the decade."
Official Account setup, friend-acquisition campaigns, segmented broadcast, rich menus, automated message flows, and the always-on CRM rhythm that turns a friend list into a real revenue line. We also operate LINE shopping and gift integrations where they fit.
Full-funnel campaigns across LINE Timeline, LINE NEWS, LINE Today, LINE VOOM, and the LINE Network's syndicated apps. Creative built for vertical, sound-on, mobile-first Japanese consumption — not exported social ads.
Yahoo! Japan search ads, display network, premium properties (Yahoo! News, Yahoo! Shopping, Yahoo! Auctions), and the Yahoo! Audience Discovery products. Account architecture, daily optimization, and integration with the LINE side of the same buying stack.
Audience targeting against the merged LINE + Yahoo! first-party signal — search intent, commerce behavior, app usage, news consumption — modeled into seed and lookalike audiences that no other Japanese ad platform can match.
Activation across Smart News, the dominant Japanese news aggregator, plus a curated set of premium Japanese publishers reachable through LY Corp supply. Native, video, and brand-safe display formats, not the open programmatic mess.
LINE Pay enablement, LINE Gift, LINE Shopping, and product-feed integrations that make LINE a transactional channel — not just a content channel. The work that quietly turns retention into a revenue compounder.
We map your category's behavior across LINE and Yahoo!, audit any existing OA or Yahoo! account, and recommend the right entry point — usually a coordinated LINE OA + LAP launch with a Yahoo! search baseline running underneath.
Official Account configuration, rich menu and message-flow design, LAP campaign architecture, Yahoo! Search and Display account, audience setup, and Japanese-language creative production with our Tokyo studio.
LINE friend acquisition, LAP performance campaigns, Yahoo! Search live, Smart News native rolling, all under one weekly operating rhythm. Reporting that treats the stack as one channel, because it is.
Monthly OA broadcast calendar, ongoing LAP iteration, quarterly Yahoo! creative refresh, and progressive expansion into LINE commerce and Pay where the funnel supports it.
A Korean clean-beauty brand was already strong at home but invisible in Japan. We launched with a coordinated LINE OA + LAP friend-acquisition program, layered a Yahoo! Search baseline against branded and category queries, and ran a Smart News native campaign for top-of-funnel storytelling. Inside fourteen months the LINE Official Account had crossed 1.4 million friends, the Yahoo! search account was profitable on first-purchase ROAS, and LINE accounted for the brand's largest Japan repeat-purchase channel.
"Deebo is the only foreign-friendly agency we've found that operates LINE the way a Japanese DTC team would. The LY Corp stack as one channel — that's the unlock."
— Global Brand Director, Korean K-beauty group
Direct partner support across LINE and Yahoo!, early access to new ad products, and the operational depth to run both sides of the stack as one — which is the entire point of the merger.
Account managers, copywriters, and creative leads who actually live in Japan, write in Japanese, and understand LINE's idiomatic communication norms — not translators sitting elsewhere.
The mistake foreign brands make is buying LINE friend-adds and then doing nothing with the audience. We engineer the full retention loop — broadcast, segmentation, automated flows, commerce — so the friend list becomes durable revenue.
Thirty minutes, no pitch deck. We listen, ask the questions that matter, and tell you what we'd actually do — even if that means recommending you don't hire us.
