Prince of Tennis Birthdays

The following is compiled from the character profiles in the Tennis no Oujisama Fanbook 20.5, with corrections and annotations by myself and various others. The ages are calculated for the current manga arc, i.e. Kantou finals during the first week of July. Remember that the Japanese school year begins in April and ends in March, and kids leave junior high at 15 (i.e. a third-year player is 14 going on 15 if his birthday falls between late July and early March, and 15 if his birthday falls between late March and early July).

Notes:

  1. Kachiro is the youngest character. Marui is the oldest. *cracks up* [Actually, Akutsu's the oldest...]
  2. For that matter, Jirou's the oldest in Hyotei.
  3. Fuji and Yuuta have birthdays ten days apart (to either side of mine ^^;), and are both young for their years. Yukimura is the youngest for his year. Thus, Fuji is closer to Kaidou's age than he is to Ooishi's, and Yukimura is closer to Kirihara's age than Sanada's. If you want to be logical about the series - always an iffy proposition - this goes a long way toward explaining why the second years are so much bigger than the first years. They're only a grade apart, but Momo is actually 1 1/2 years older than Ryouma; Kaidou is nearly 2 years older than Kachiro.
  4. Inui is exactly one day older than Renji. They're the only ones to have June birthdays.
  5. Most all the Hyotei third years have their birthdays in September-October.
  6. Ryouma was born on Christmas Eve, Dan on the day after New Year's, Kaneda on New Year's Eve and Ohtori on Valentine's Day.
  7. People with the same birthdays (the j-fen have a lot of fun with this):
    -- Shishido and Kurobane (September 29)
    -- Horio and Kirihara (September 25)
    -- Shinji and Jackal (November 3)
    -- the Kisarazu twins (well, duh - November 20)
    -- Ikeda and Sakurai (July 18)
  8. My impression was right: there really are twice as many charas born in July-December as January-June.
    January: 2 / February 4 / March: 3 / April: 5 / May: 4 / June: 2 / July: 5 / August: 5 / September: 6 / October: 8 / November: 9 / December: 6
  9. I double-checked the star signs and cusps against Tarot.com, so complain to them if you don't agree. XD
