Hidetoshi Katori
engineer in Japan

Hidetoshi Katori (香取秀俊, Katori Hidetoshi; born 27 September 1964) is a Japanese physicist and professor at the University of Tokyo best known for having invented the magic wavelength technique for ultra precise optical lattice atomic clocks. Since 2011, Katori is also Chief Scientist at the Quantum Metrology Lab, RIKEN.
Recently, Katori's group performed a measurement of gravitational redshift with two transportable strontium optical lattice clocks over nearly the entire height of the Tokyo Skytree, setting a new record for the best ground-based test of general relativity.

This brief starts where responsible research should: with the source description of “Hidetoshi Katori” as engineer in Japan. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the people & ideas register because the source frames it as engineer in Japan. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The entry’s evidential value lies in the named roles, institutions and publications that can be tested against primary documentation. The source revision retrieved here is dated Aug 29, 2026. The linked authority identifier is Q21698500. VIAF identifies the subject as 128251546. The Library of Congress control number is no2010105151. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1964, 2011, 2005 and 2006.
Later biographies can compress uncertainty and repeat inherited reputations, so apparently settled claims may still require comparison. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Read biographical claims against dates, named institutions and the cited references. Distinguish a subject’s later reputation from evidence produced during their lifetime.
- Establishing names and roles
- Building a first chronology
- Locating cited institutions
Personal papers, civil or court records, institutional files and the scholarship cited by the source.
Three-step research path
- Establish the record: confirm the title “Hidetoshi Katori”, its source revision and the description used here.
- Expand the search: follow Hidetoshi Katori primary sources, Hidetoshi Katori archive and Hidetoshi research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
Questions for further research
- Which source most directly establishes the central claim about “Hidetoshi Katori”?
- How has the subject’s reputation changed across later accounts?
- Which primary records establish identity, chronology and institutional ties?
