Tokyo Imperial University LB-2
type of aircraft
The Tokyo Imperial University LB-2 was a small, single-engined light civil aircraft, designed by students of the Tokyo Imperial University as a two-year project. The sole example first flew in December 1939.
Design and development
The aeronautics divisions of German universities had a tradition of student design projects, often gliders. In 1936 students at the Tokyo Imperial began a similar, two-year project, though for a small two seat powered aircraft. Their first design, the LB-1 (LB for light blue, the school colour), with side-by side seats was abandoned in favour of the LB-2 which had tandem seats.
It was a conventional high wing aircraft, though with an unusually refined wing plan; the inner half was rectangular but the outer panels were pointedly elliptical. Like the rest of the aircraft the wing structure was wooden and its covering fabric. The LB-2 was powered by a 60 hp (45 kW) air-cooled, inverted, six cylinder Train 6C, a French engine which proved unreliable.
Behind the engine the fuselage was flat sided, with an enclosed cabin under the wing. The tail was conventional with its tailplane on top of the fuselage and a triangular fin mounting a rounded rudder.
This brief starts where responsible research should: with the source description of “Tokyo Imperial University LB-2” as type of aircraft. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as type of aircraft. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Dec 27, 2025. The linked authority identifier is Q104873022. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1939 and 1936.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
