I am an Associate Professor at the Historiographical Institute, The University of Tokyo, working at the intersection of digital humanities and information technology. I build open-source software that helps researchers create, structure, and use cultural and historical data.
My work centers on IIIF (International Image Interoperability Framework), Linked Open Data, TEI, and digital archives — connecting images, texts, and metadata so that historical materials become computable and reusable. I am especially interested in lowering the barrier between humanities researchers and the tools that make their sources discoverable.
Research focus
- IIIF & digital archives — viewers, annotation, and georeferencing tools for cultural collections
- Linked Open Data for the humanities — modeling and publishing historical knowledge
- TEI & text encoding — collaborative OCR correction and structured text for East Asian materials
- Long-term preservation — OAIS-based archival workflows (Archivematica, Omeka S)
At a glance
- 130 papers, 14 books, and 123 presentations (researchmap)
- 21 academic awards across digital archives, Linked Open Data, and information processing communities
- Program Committee Chair for JADH (Japanese Association for Digital Humanities); active in the TEI East Asian / Japanese SIG
- 388+ open-source repositories on GitHub
Selected software
Most of my tools are open source and built around IIIF and Linked Data. A few starting points:
- IIIF Discovery in Japan — finding and aggregating IIIF resources
- nuxt-mirador — integrating the Mirador 3 viewer
- IIIF Georeference viewer — maps with the IIIF Georeference Extension

東京大学史料編纂所 准教授。人文情報学（デジタル・ヒューマニティーズ） を専門とし、史料・文化資料をコンピュータで扱えるようにするためのオープンソースソフトウェアを開発しています。
IIIF・Linked Open Data・TEI・デジタルアーカイブ を軸に、画像・テキスト・メタデータをつなぎ、歴史資料の発見可能性と再利用性を高めることに取り組んでいます。研究者が自分の史料をより使いやすくするための「道具」を作ることに関心があります。
