Waseda University — Probable Classmates of My Maternal Grandfather

§1 · The Enrollment Window Problem: Prewar vs. Postwar Systems

Japan ran two completely distinct university systems across the period a person born 1923–24 would plausibly have studied at Waseda. The family recollection of "4 years" points toward the postwar standard — but a prewar student in law was on a 3-year track. Both scenarios are reconstructed below.

The broadest plausible campus window for someone born 1923–24 at Waseda law is roughly 1940 to 1955, with the tightest probable core being 1941–1948 (prewar track, with wartime disruption) or 1949–1953 (postwar 4-year track).

§2 · Whole-University Co-Campus Alumni (Documented)

All persons below have confirmed Waseda enrollment overlapping at least one plausible window above. Organized by likelihood of co-campus overlap, descending.

Tier A — Highest overlap probability (same birth cohort, campus 1941–1947)

Tier B — Probable partial overlap (entered later or confirmed postwar period only)

§3 · Waseda Law Faculty (法学部) — Narrowed Analysis

What the law faculty co-year pool would have looked like

For a student born 1923–24 in the prewar 大学部 法学部 (via higher school), the typical cohort entering law around 1943–44 would graduate 1946–47. For the 専門部 法律科 entering 1941–42, they would graduate 1943–45 (compressed by wartime). In either case the mobilization of October 1943 disrupted normal graduation. The true graduating class of this cohort in law is therefore scattered across 1943–1949 depending on individual military service length.

Most prominent Waseda politicians of this generation studied 政治経済学部 (Politics & Economics) or 商学部 (Commerce) rather than law. Law-track alumni who entered careers in the private sector, prefectural government, or as mid-level bureaucrats are systematically absent from public biographical records — which is precisely why the NDL alumni rosters in §6 are the most valuable next step.

§4 · Key Historical Context

• 1 学徒出陣 (Gakuto Shutsujin), October 2–21, 1943 — precise figures. Imperial Ordinance No. 755 (promulgated October 2, 1943) abolished draft deferments for all liberal-arts and law students born between April 2, 1920 and December 1, 1923. The October 21 send-off at Meiji Jingū Gaien Stadium involved approximately 25,000 conscripted students from 77 Kantō-region schools, watched by roughly 50,000 science and female students. Waseda's own 歴史館 records that over 4,500 Waseda students became newly draft-eligible and more than 5,700 had entered the military by March 1944. The university's 戦争犠牲者データベース documents 4,735 Waseda student war dead (drawn from 『早稲田大学百年史』第四巻 and 『早稲田大学史記要』第34・36・39巻). A maternal grandfather born in 1923 was in the direct first wave; born in 1924, he faced the lowered conscription age (from 20 to 19) imposed in October 1944. 陳文寬 was mobilized into the Imperial Japanese Navy under this ordinance and served in Tokyo — he never left the city.
• 2 Waseda campus firebombing and reconstruction. Much of the Waseda campus was destroyed in the Tokyo firebombing raids of 1945. Classes resumed within one month of Japan's surrender in August 1945, but the university was not reorganized as a "new university" under postwar education reform until 1949. Any student enrolled 1943–46 was studying in disrupted, physically diminished conditions. The new 4-year system started accepting students in April 1949.
• 3 Taiwanese and Korean students at Waseda. Waseda was the first Japanese university to actively recruit Asian students. During Japan's colonial period (Taiwan: 1895–1945; Korea: 1910–1945), Taiwanese and Korean students studied as imperial subjects. If the maternal grandfather was Taiwanese or Korean, his Waseda enrollment was entirely normal for this era. Shin Kyuk-ho (Lotte founder, born 1921) is the most prominent confirmed example of a Korean student at Waseda in exactly this period. Waseda maintained a dedicated School for Chinese Students (支那人留学生の学科), whose 110th anniversary was commemorated by the university in recent years.
• 4 Postwar "returning student" phenomenon. A large number of men born 1918–1927 resumed or began university studies after 1945. The new 4-year system (April 1949) specifically accommodated these older students — a man born 1924 entering law in 1949 at age 25 was common, not exceptional. This is the most likely explanation for the family's memory of "4 years" (the postwar program ran 4 years; the prewar 法学部 ran only 3).
• 5 Waseda's law degree as a career pipeline. In Japan's prewar and postwar era, a law degree was the standard entry into the bureaucracy, judiciary, and politics. The 法学部 at Waseda and Tokyo University produced the majority of Japan's political class. A Waseda law graduate from 1923–24 who remained in Japan would most likely have entered: (a) a government ministry via the national civil service exam (高等文官試験 prewar / 国家公務員上級試験 postwar), (b) private legal practice after passing the bar examination (司法試験), (c) corporate legal counsel, or (d) local/prefectural politics. The vast majority of this cohort pursued careers in (a) or (c) — successful and influential, but not nationally famous.
• 6 The wartime campus political atmosphere — NOT left-wing. This is addressed directly in §4, Note 7 below, but deserves separate emphasis: the Waseda campus in 1941–1945 operated under total wartime state control. The Peace Preservation Law (治安維持法) had comprehensively suppressed all left-wing organizations by the early 1930s. Any student with communist or socialist sympathies who survived the 1930s purges was either imprisoned, in exile, or in deep underground concealment. The campus your maternal grandfather encountered in 1941–1944 was characterized by nationalism, militarism, and imperial state ideology — not Marxism.
• 7 Political orientation of this cohort — mostly LDP conservative, not communist. Among documented career politicians from this exact Waseda generation, the dominant political color is conservative/right: Takeshita (LDP PM), Masaoka (LDP Health Minister), Tanaka Rokusuke (LDP MITI Minister and Secretary-General), Fujita (LDP, House of Councillors President). The only JSP-aligned figure in the documented set is Tagaya Shinnen (多賀谷真稔) — and the JSP (Japan Socialist Party) was a social-democratic party, not communist. It was roughly equivalent to the UK Labour Party or Germany's SPD: pro-trade-union, anti-war, democratically committed, and explicitly distinct from the Japan Communist Party (日本共産党/JCP). Calling JSP members "communist" is a category error. Waseda does have a historically more liberal/independent reputation than Tokyo Imperial University, and the 1960s–70s saw strong student leftism there — but that was a different generation, 20 years after the wartime cohort.

§7 · Cohort Size: How Many Law Students Were There?

The following estimates are reconstructed from institutional anchors across the wartime and postwar enrollment periods.

Of the roughly 700–1,200 law-track students entering Waseda per year in normal prewar times, most went on to careers as lawyers, bureaucrats, corporate counsel, and local politicians — successful and influential, but not nationally prominent. The NDL 会員名簿 別冊(学科年度別) (pid/9544635) is the path to named graduates from these cohorts.
