Francis Kibiwott and Alevtina Ivanova are the current men's and women's course record holders. The 1999 route was aided by a downhill net drop of 4.27 m/km (just under the allowable limit), while the editions from 2000 to 2003 had an excessive drop of over 5 m/km, making them ineligible for record performances.[4] The current route is relatively flat, however, with the race having an overall total incline of 5 m from start to finish.[5]
The historical root of the competition lies with the Shinmai Marathon which was first held in 1958. The marathon came under its current moniker in 1999. The elite race is international in nature, with a number of foreign runners being invited each year, although prominent Japanese athletes also take part.[6]Kenyans have won the majority of the men's races while Russians have dominated the women's race. Nephat Kinyanjui of Kenya won the race a record three times consecutively between 2006 and 2008. Since its rebirth in 1999, only two Japanese runners have won the race (Akiyo Onishi in 1999 and Yuki Kawauchi in 2013).[7]
