Ode to cherry blossoms ( sakura )
振り向かば枝にはじけて開くらむ さくらさくらは夢に見るごと
Cherry blossoms will burst out blooming
on each of the branches
as though I will see them in a dream,
if I'll look back just now (haricot)

Once a cherry blossom starts to open up, all of blossoms will be at their peak before long, and it gives us somehow unreal state of mind.
And, even when people undergo their hardship, looking up to see these transient blossoms brings brightness into their hearts and appreciating their short lives makes people feel special sentiment.
Cherry Blossoms ( sakura ) have been one of major material of Tanka poem from ancient days in Japan, e.g. being expressed in "manyo-shu"The Anthology of Myriad [Ten Thousand] Leaves, compiled in the 8 century. And of course it is still continuing to be written suggesting some theme in genre of modern tanka.
In this time of year I often remember a tanka composed by Kanoko Okamoto(1889~ 1939), about 100 years ago.
桜ばないのち一ぱいに咲くからに生命(いのち)をかけてわが眺めたり
岡本 かの子
( As cherry blossoms bloom their full of lives with all the strength they have, I gaze them with my tremendous dignity and utmost power of my life.)

This tanka expresses not only nature of cherry blossoms but also Kanoko's passionate life. I've ever read that when she faced with her quite difficult situation, her partner and a cartoonist, Ippei Okamoto, let her intimate two boyfriends live with them to encourage her. Their intense way of living exerted influence on their youngest son, Tarō Okamoto, by necessity.
As an avant-garde painter,Tarō Okamoto designed 「太陽の塔」,( Tower of the Sun ) for a symbol tower of world exposition that was held in 1970 in Japan.
This year(2011) is 100th anniversary of his birth.

Ten years later of the event, so-called "Bubble economy " term started and it lasted nearly a decade in Japan. In the midst of the bubble economy, Machi Tawara(1962~ ) who is a forefront of colloquial tanka poem wrote about transient nature of cherry blossoms like this.
さくらさくらさくら咲き初め咲き終わりなにもなかったような公園
俵 万智
( Sakura sakura, their floral term broke out and came to an end,
then the park stays totally as it used to be.)
Since the period of bubble economy terminated, in Japan people have struggled with prolonged recession.
And now, aftermath of the unprecedented earthquake and tsunami, including trouble of leak of radioactivity from power plants, makes people get to grips with new phase of difficulties.
New term of challenge ourselves has begun.
