The championships are both held in January and are divided by gender. The Empress Cup - Interprefectural Women's Ekiden is held in Kyoto on the third Sunday in January. The Interprefectural Men's Ekiden is held in Hiroshima in recent years on the fourth Sunday of January. Women's Championship
The Empress Cup - Interprefectural Women's Ekiden Championship is held in Kyoto on the third Sunday in January. The 2012 running marks the 30th annual event. Forty seven teams from the 47 prefectures of Japan compete. The course is the same as the course for the high school boys national ekiden race held on the third Sunday of December, except that the women's relay has 9 stages (rather than 7) over the 42.195 kilometers. The stages are 6k  4k  3k  4k  4.0175k  4.0875k  4k  3k and 10k. The two 3k stages are reserved for junior high athletes and generally high school athletes run the 5 stages that are 4k or just over 4k. Collegiate and open runners take the 6k and 10k stages. The mixed-age squads maintain a rapid pace. In 2009 the first 10 team teams finished under 2 hours and 20 minutes, and 12 teams broke 2:20 in 2012. In 2009, the team from Kyoto took its 13th championship, and as of that year, in the ekiden's 20 years Kyoto has only twice placed outside the top 6. Okayama took its first ever title in 2010, Kyoto reclaimed it in 2011, and in 2012 Kyoto finished second, a minute back from the winning team from neighboring Osaka.
