+# The modified Hepburn system for the romanization of Japanese has been
+# in use by the U.S. Board on Geographic Names since about 1930 and has
+# been used extensively in the romanization of Japanese geographic names.
+# The system is well adapted to the general needs of speakers of English
+# and is the most widely used system for the romanization of Japanese.
