This phrase originates from The Book of Five Rings by the swordsman Miyamoto Musashi.
Literally, it is a four-character idiom that expresses the idea that no matter how far you go, the world lies under the same sky.
By extension, it has come to mean “to keep striving toward a single goal.” The higher the goal, the longer the journey and the more effort it requires.
Like the sky that stretches on forever, a bright future surely awaits beyond those efforts.
When times are tough, look up at the sky and remember these words.
The return of the sun; the turning of the tide toward good fortune (often used to mean a revival or a new beginning after adversity).

Like the end of a cold winter and the gentle return of spring, the four-character idiom “Ichiyō Raifuku” means that good fortune comes after a spell of misfortune.
On days when you fail at studying or sports, or when something sad happens, you may worry that things will stay this way forever.
Even so, time moves forward little by little, and a new light begins to shine into your heart.
Even if school life doesn’t go smoothly, by continuing to move forward—even if only in small steps—the situation will surely change.
It is a four-character idiom that gives you the courage to keep hope in your heart.
soaring spirit; indomitable morale; spirits running high

When it looks like you’re about to lose a match, even if you tell yourself not to lose heart, your morale inevitably dips, doesn’t it? That’s exactly when I want you to remember this phrase: “ikishōten” (意気衝天).
It describes a state of being extremely motivated and brimming with energy.
If you recall it when you need a boost, it might help lift your spirits.
And once your mindset rebounds, you may start to see a path to victory in the match.
It’s a very positive expression, so be sure to keep it in mind!
