Monthly budgets for mid-market companies typically range from ¥500,000 to ¥3,000,000 depending on channel mix and growth objectives. Market-testing budgets start at ¥500,000–1,000,000/month for one or two high-intent channels, while committed growth programs investing across search, SEO, social, and email run ¥2,000,000–5,000,000/month. We design every budget around your specific industry benchmarks and ROI targets.
Japanese-language SEO typically takes 8–14 months to reach meaningful organic traffic in competitive verticals. Initial indexing and impression gains appear in months 1–3, momentum builds in months 4–6, and the inflection point — when pages break onto page one for target queries — typically arrives between months 7–12. We pair SEO with PPC from day one so you capture demand immediately while organic visibility compounds.
Yes. While Google holds roughly 75% of Japan’s search market, Yahoo Japan retains a steady 20–25% share with a user base that skews older and more regional. Running campaigns only on Google leaves up to a quarter of your potential audience unreached. Each platform has a separate advertising system with its own auction dynamics, so we manage both with independent keyword research and bid strategies.
Japanese B2B purchases involve 4–6 stakeholders and average 4–8 months from first contact to signed contract — significantly longer than Western markets. The nemawashi process (consensus-building before formal decisions) means your marketing must reach and persuade multiple decision-makers over time. We adapt lead scoring, attribution windows, and nurture sequences to match these extended timelines.
Absolutely. DMPJ operates bilingually at a strategic level — we brief creative teams in Japanese, present performance reports to international leadership in English, and translate campaign strategy across both markets. This eliminates the friction that arises when companies coordinate between separate translation, media buying, and strategy vendors.
