DIME Magazine, took a look at how the Japanese view the beginning of Spring and came up with the following guides:
1. The cherry blossom season
The first blooming of sakura is a defining moment in the changeover from Winter to Spring. Taking the average date when the sakura first bloom over 68 locations within Japan the following data was obtained for the years 1999-2008.
The average date over the 10 years was March 29th.
2. New songs about Spring
Songs about Spring are strong in the heart of the public, just as songs of graduation and farewell. There have been some memorable Spring songs over the years including Haru Ichiban by the Candies, Haru yo Koi by Matutoya Yumi and SakuraZaka by Fukuyama Masaharu.
Taking a selection of top 10 hit Spring songs and using their first release date, the average date from the 10 years was May 9th.
3. JR Train timetables
A long time favorite to donate the change of seasons from winter into Spring has been the Japan Railways (JR) train timetable changes. Each year a new timetable is published showing the train schedules. Over the last 10 years the timetable has been published on: March 13, March 11, March 3, March 16, March 15, March 13, March 1, March 18, March 18 and March 15.
The average of these 10 years is March 13th.
4. Doraemon movie
Finally and popular with the kids, since 1980 every year in Spring, a new Doraemon movie has been released at cinemas. (The only year without a movie was 2005 when the voice of some of the key characters changed).
Since 1980 the dates have all been in March on the following dates: 15, 14, 13, 12, 17, 16, 15, 14, 12, 11, 10, 9, 7, 6, 12, 4, 2, 8, 7, 6, 11, 10, 9, 8, 6, 4, 10, 8, 7.
The average date from all these years is March 10th.
Here is the trailer for the 2009 Doraemon movie
It sounds like Doraemon may be the most consistent and perhaps the most memorable. From now on I might have look at the start of Spring as being the release of the Doraemon movie.
What are your thoughts on the date for Spring?
Do you have another set of data we could use to calculate it?
