Other dams that were once on postage stamps are all major large dams in Japan: Sakuma Dam (the Tenryu-gawa River), Ogochi Dam (the Tama-gawa River), Kurobe Dam (the Kurobe-gawa River), and Nukui Dam (the Takiyama-gawa River). ダムが切手の図案に選ばれたのは佐久間ダム(天竜川)・小河内ダム(多摩川)・黒部ダム(黒部川)・温井ダム(滝山川)と他には日本屈指のハイダムしかない。 |
