A demographer who untangles the data—and drives action.

I bridge research, public communication, and policy implementation on Japan’s low fertility and family change.

Position

I challenge the old split: academics staying in the ivory tower vs communicators lacking rigour. I aim to do both—publishable research and practical implementation—while communicating clearly to the public and media.

Three pillars

• Research — Publications in Demography and Social Forces. General-audience book (Winter 2026).
• Public communication — Columns, note, YouTube/Podcast. Fact literacy for better debate.
• Policy implementation — Dashboards & communication manuals with local governments.

Selected work

• City dashboard: “ideal number of children” — common evidence base for policy design
• Communication manual & templates — reduced misinterpretation in public materials
