<P> Before the vote, there were calls for the bills to be separated at the Diet . Waseda University professor Norihiro Kato stated that Kimigayo is a separate issue more complex than the Hinomaru flag . Attempts to designate only the Hinomaru as the national flag by the DPJ and other parties during the vote of the bill were rejected by the Diet . The House of Representatives passed the bill on July 22, 1999, by a 403 to 86 vote . The legislation was sent to the House of Councilors on July 28 and was passed on August 9 . It was enacted into law on August 13 . </P> <P> On August 8, 2009, a photograph was taken at a DPJ rally for the House of Representatives election showing a banner that was hanging from a ceiling . The banner was made of two Hinomaru flags cut and sewn together to form the shape of the DPJ logo . This infuriated the LDP and Prime Minister Tarō Asō, saying this act was unforgivable . In response, DPJ President Yukio Hatoyama (who voted for the Law Regarding the National Flag and National Anthem) said that the banner was not the Hinomaru and should not be regarded as such . </P> <P> Passed in 1870, the Prime Minister's Proclamation No. 57 had two provisions related to the national flag . The first provision specified who flew the flag and how it was flown; the second specified how the flag was made . The ratio was seven units width and ten units length (7: 10). The red disc, which represents the sun, was calculated to be three - fifths of the hoist width . The law decreed the disc to be in the center, but it was usually placed one - hundredth (​ ⁄) towards the hoist . On October 3 of the same year, regulations about the design of the merchant ensign and other naval flags were passed . For the merchant flag, the ratio was two units width and three units length (2: 3). The size of the disc remained the same, but the sun disc was placed one - twentieth (​ ⁄) towards the hoist . </P> <P> When the Law Regarding the National Flag and National Anthem passed, the dimensions of the flag were slightly altered . The overall ratio of the flag was changed to two units width by three units length (2: 3). The red disc was shifted towards dead center, but the overall size of the disc stayed the same . The background of the flag is white and the sun disc is red (紅色, beni iro), but the exact color shades were not defined in the 1999 law . The only hint given about the red color that it is a "deep" shade . </P>
