01
CAC/ROAS Baseline Audit — Japan
We establish a documented, Japan-specific baseline for cost of acquisition and return on ad spend across Google Ads and Yahoo Japan Ads — by channel, campaign type, and audience segment. The audit examines conversion path integrity, attribution configuration, and whether your reported CPA reflects actual acquisition economics or is distorted by attribution overlap between the two primary Japan channels. The baseline is the anchor for every scaling decision that follows.
02
Campaign Profitability Segmentation
We segment your Japan campaign portfolio by contribution margin — accounting for product or service margins and customer lifetime value where data permits. The segmentation identifies which campaigns are genuinely profitable at current spend, which are break-even, and which are loss-making. For Japan campaigns, this segmentation frequently surfaces that Yahoo Japan and Google campaigns serving the same audience generate materially different CPAs — a distinction that blended reporting obscures.
03
Scaling Roadmap with Spend-Tier Gates
We build a phased scaling roadmap structured around your current Japan spend level — typically beginning from ¥500,000–¥3,000,000 per month — with defined performance gates at each tier. Each gate specifies the CPA threshold, ROAS floor, and lead quality signal required before the next budget increase is approved. The roadmap accounts for the distinct scaling dynamics of Google and Yahoo Japan, including the different audience saturation curves and bid landscape behaviour on each platform.
04
Budget Allocation Model
We produce a working budget allocation model that distributes spend across your profitable Japan campaign segments, balances investment across Google and Yahoo Japan based on marginal CPA data, and stress-tests allocation decisions against your historical performance. The model is built to be updated by your team as actuals come in — it reflects the Japan market specifically, not a generic paid media allocation framework.
05
Channel Diversification Planning — Japan Context
We assess the conditions under which expanding beyond Google and Yahoo Japan is warranted for your specific acquisition objectives. Japan's paid media landscape includes Line Ads, programmatic display, and vertical-specific inventory — each with distinct audience characteristics and CPA profiles. The diversification plan identifies which channels are relevant to your acquisition goals, what the entry conditions are, and how they would be sequenced relative to scaling your core channels.
