The Japanese phrase 'サクラサク' (Sakurasaku), literally means cherry blossoms will grow. This phrase is often said to students who are taking exams to graduate in March, and is often printed on various stationary including pencils and notebooks for exam success. It is sort of a good luck phrase, meaning that in the spring, your blossoms will bloom. Of course the cherry blossoms we see bloom, but your personal blossoms inside your heart will bloom depending on your success.
Also helping to exam success, many companies, (especially food) are bring out special 'lucky' products. Eating the lucky Pocky or Kit Kats while studying are said to have psychological benefits as well as an excuse snack! In Japanese, Kit Kat (キットカット) sounds similar to Kitto Katsu (キットカツ) which translates to: ' You will win'. Also the snack brand Curl (カール) have products named Ucurl (ウカール), an adaptation of the word ukaru (受かる) which means pass.
Congratulations to all who graduated this year!
