system of writing Japanese completely by a romanized system, which he felt would make it easier for Japan to compete with Western countries. Since the system was intended for Japanese people to use to write their own language, it is much more regular than Hepburn romanization, and unlike Hepburn's system, it makes no effort to make itself easier to pronounce for English-speakers. Nihon-shiki was followed by Kunrei-shiki, which was adopted in 1937, after a political debate over whether Nihon-shiki or Hepburn-shiki should be used by the Japanese government. Kunrei is otherwise nearly identical, but it merges syllable pairs di/zi ぢ/じ, du/zu づ/ず, dya/zya ぢゃ/じゃ, dyu/zyu ぢゅ/じゅ, dyo/zyo ぢょ/じょ, wi/i ゐ/い, we/e ゑ/え, kwa/ka くゎ/か, and gwa/ga ぐゎ/が, whose pronunciations in Modern Standard Japanese are now identical. For example, the word かなづかい, rendered ''kanadukai'' in Nihon-shiki, is pronounced as ''kanazukai'' in modern Japanese, and is romanized as such in Kunrei. However, some Japanese-speakers still distinguish di from zi and du from zu and so Nihon-shiki spelling is not entirely obsolete. Nihon-shiki is considered the most regular of the romanization systems for the Japanese language because it maintains a strict "one kana, two letters" form. Because it has unique forms corresponding to each of the respective pairs of ''kana'' homophones listed above, it is the only formal system of romanization that can allow (almost) lossless ("round trip") mapping, but the standard does not mandate the precise spellings needed to distinguish ô 王/おう, ou 追う/おう and oo 大/おお.
