[email protected] Minoru Kawada (Graduate School of Environmental Studies, Nagoya University, Japan) Hamaguchi Osachi is one of the most important Japanese politicians in history. He helped bring about the Japan-China Tariff Treaty, introduced the gold standard, and concluded the London Naval Disarmament Treaty as Japanese prime minister in the early-Showa era. This paper studies the ideas behind his domestic policy, considering the political situation around him. Specifically, it deals with Hamaguchi’s criticism of the domestic policy of the Tanaka administration, his stimulative measures, his theory of the constitution and social policy, and his correspondence about the political situation concerning the actions of the Seiyukai and the Minseito, etc. These are part of the study of Hamaguchi’s political ideas and the political environment at that time. 11 1931 6 4 8 Hamaguchi Osachi, domestic policy, early Showa era, Tanaka administration, Minseito, Seiyukai 1927 1927 2 4 17 2 1929 4 1931 6 20 166 158 88 460 6 1 5 5 2 2 (1) 1870 3 (2) 1929 4 7 (3) Journal of Human Environmental Studies, Volume 1, Number 1 8 3 (4) 1 (6) 6 52 219 161 2 69 7 190 8 8 9 (7) 1927 17 2 7000 2 (8) 8000 (9) 3 (5) (10) 1 1 Minoru Kawada: The domestic policy of Hamaguchi Osachi in the early Showa (15) 34 38 44 110 (16) (11) (12) (17) 1927 2 9 1488 10 793 556 920 4 7500 (18) 324 1 2 20 (13) 3500 7500 6 12 (14) 11 2 1 (19) Journal of Human Environmental Studies, Volume 1, Number 1 40 (20) (23) 1917 6 (21) (24) (25) (22) 1924 13 1 1 Minoru Kawada: The domestic policy of Hamaguchi Osachi in the early Showa (29) 1927 19 9200 1 8600 21 2 2 7900 9300 1919 8 41 11 8000 22 13 2 (26) 100 50 44 58 3 (30) (27) 1917 6 1919 1925 1920 1923 9 12 (31) (32) (28) 6700 5 (33) Journal of Human Environmental Studies, Volume 1, Number 1 (38) 5 5 (34) 17 7400 1 9900 (39) (35) (40) 5 (36) (41) 3 8000 35 (37) (42) 1 1 Minoru Kawada: The domestic policy of Hamaguchi Osachi in the early Showa (45) (43) (46) (47) (48) (44) 1928 3 2 20 217 216 8 4 18 29 3 466 2 1 1924 13 3 230 9 Journal of Human Environmental Studies, Volume 1, Number 1 227 (49) (53) (54) (55) 30 (50) 4 1 4 (56) 3 1600 (51) 148 469 301 1701 63 164 (52) (57) 340 1 1 15 500 Minoru Kawada: The domestic policy of Hamaguchi Osachi in the early Showa 5 3 6 7 4 19 (58) 8 25 5 5 7 5 (61) 220 176 12 3 (59) 3 41 24 56 25 6 8000 (62) 1 2800 2 (60) Journal of Human Environmental Studies, Volume 1, Number 1 58 8000 7000 (67) (63) (64) (68) 1 5000 (69) 2 (65) 1 1700 3900 1929 (66) 4 5 185 25 249 56 2 249 170 (70) 2 1 1 Minoru Kawada: The domestic policy of Hamaguchi Osachi in the early Showa (19) 1 2 1 5 2 9500 90 (20) 44 42 1927 11 341 345 455 456 (21) 1917 4 (22) 311 312 (23) 1924 3 (71) (24) 25 (25) 1927 6 91 1928 9 (26) 7 2 26 1927 6 27 1927 8 50 1927 11 56 58 59 (27) (28) 1928 1 98 101 1928 9 (29) 50 1927 11 59 1928 1 (1) 934 2000 (2) 6 (3) 50 15 (4) 16 48 108 1 24 99 30 1928 9 1927 8 3 4 1933 298 29 1927 (30) 402 403 1988 153 1975 116 1920 1920 1983 92 110 98 1928 9 124 1929 1 130 1929 6 1995 (5) 2000 8 (6) (31) 1939 78 2 56 76 1 21 390 (32) (7) 29 30 1927 (33) 391 3 7 21 48 49 8 (8) 1928 1958 916 29 1927 8 36 1927 9 30 1927 8 185 1929 10 (9) (10) (11) (12) 1 1 30 37 8 9 31 40 1927 1927 388 399 420 (35) 49 1927 11 57 1928 (36) 1 (37) 1920 116 89 (38) 1097 388 390 (39) 61 43 (14) (40) 51 (15) (16) 1 (17) 3 1999 1931 55 89 31 1928 1927 11 62 1928 1 1 (41) 1927 8 4 1981 3 (42) 31 11 58 1 (34) 67 (13) 1927 57 32 1927 1 8 166 167 122 63 64 1928 43 1927 11 (18) 19 97 1976 (43) 53 1 Journal of Human Environmental Studies, Volume 1, Number 1 1928 (44) 51 1927 11 (45) (46) 59 1928 60 1 (47) (48) 48 388 427 1890 1937 (49) 235 (50) 1931 102 104 94 100 (51) (52) 2 25 2 20 (53) (54) 96 (55) 68 (56) 194 (57) 204 80 1928 4 102 1928 9 (58) 98 5 25 (59) (60) 86 1928 6 (61) (62) (63) 92 1928 9 98 99 1928 112 113 100 101 12 (64) 141 (65) 1928 9 (66) 50 397 423 533 (67) 1928 1 9 124 (68) 101 1929 102 103 115 1928 9 1928 12 (69) 117 (70) 106 1928 11 115 1928 12 1929 1 129 1929 3 (71) 130 2003 6 6 2003 133 6 1929 3 27 1 1
