In music, the notes of an octave are named i ro ha ni ho he to, written in katakana.
Iroha is also used in numbering the classes of the conventional train cars of Japanese National Railways (now known as JR). I is first class (no longer used), Ro is second class (now "Green car") and Ha is third class (standard carriages). Some Japanese expressions need knowledge of iroha to understand. The word iroha (イロハ, often in katakana) itself can mean "the basics" in Japanese, comparable to the term "the ABCs" in English. Similarly, iroha no i (イロハのイ) means "the most basic element of all". I no ichiban (いの一番, "number one of i") means "the very first". |
