Source-derived summary

Tetsuya Fujii (藤井哲也, Fujii Tetsuya; born 1960) is a Japanese amateur astronomer and prolific discoverer of minor planets.

From 1988 to 1992, he had discovered a total of 22 numbered asteroids together with his colleague, Kazuro Watanabe, at the Kitami Observatory in the Kitami-Abashiri Region Cultural Centre in eastern Hokkaidō, Japan, where several amateur astronomers have been conducting an active program of astrometric observations of minor planets and comets. He is director of the astronomical club in Kitami, where he also works for the NHK broadcasting office.

The minor planet 4343 Tetsuya, discovered by Seiji Ueda and Hiroshi Kaneda in 1988, was named in his honour.

Editorial summary

This brief starts where responsible research should: with the source description of “Tetsuya Fujii” as japanese astronomer. Everything that follows is an evidence route, not borrowed authority.

The current lead gives the account dated anchors—1960, 1988, 1992—that can be checked directly. The linked authority record independently contributes the date 1960-01-01.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as japanese astronomer. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Dec 29, 2025. The linked authority identifier is Q1634658. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1960, 1988 and 1992.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. 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

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
