The data nobody else analyses, for the decisions that matter.

Data scientist based in Tokyo, I analyse the data hidden behind language barriers or methodological gaps — Japanese patents, pricing signals, marketing performance — and turn them into quantified recommendations.

The problem

You have data. But do you have answers?

Your Japanese competitors are filing patents, signing alliances, investing in R&D. And you don’t see it.

The data is public, freely available on J-PlatPat. But it’s in Japanese, and interpreting it requires a rare combination of technical and linguistic expertise.

How many strategic decisions are you making without seeing what your Japanese competitors are actually doing?

Is your pricing really optimal?

Most pricing policies are built on intuition and history, never properly reviewed with structured data. Underpriced products can subsidise your customers’ margins for years without any clear alarm signal.

Knowing exactly where your prices underperform, by how much, and what to do about it changes the decision.

Your campaign generated +15% in sales. Did it, really?

Or was the market already rising? Without rigorous method, you’re optimising in the dark. Dashboards show numbers — they don’t show causes.

Misattributed performance: you’ve been allocating budget to the wrong channels for months.

You see a correlation in your data. But is that the actual cause?

Acting on the wrong lever means investing in the wrong place. Causal inference separates what truly causes a result from what is merely correlated with it.

A decision built on a spurious correlation can cost months of wasted optimisation.

Causal Inference & Decision Science

Identifying what truly causes a result, not just what correlates with it. So you invest in the right lever, with an explicit quantification of uncertainty.

Who is this for?

I work with:

  • Leaders of SMEs and mid-size companies who want quantified answers, not more reports
  • Marketing directors who want to measure what actually works in their mix
  • Commercial directors who suspect their pricing policy is not optimal
  • European companies who need to understand what Japanese players in their sector are doing

My approach

Primary data. Rigorous methods. Actionable recommendations.

I work on primary data, not second-hand reports. Each analysis combines structured data extraction (patents, transactions, marketing data), rigorous quantitative methods, and contextual interpretation.

The result: quantified recommendations with an explicit measure of uncertainty. You will know what you can assert, and what remains to be verified.
