Return of the wreath
再次使用花環標識

One particularly popular idea is for Tokyo to reuse the logo it had during its Olympic bid as a candidate city. Created by design student Ai Shimamine, the logo depicts a wreath of cherry blossoms. The wreath -which symbolizes a return - has two meanings in the logo, according to committee chief Masato Mizuno. "It is the idea of 'coming back again'... the Olympic Games coming back to Tokyo and Japan coming back (from the Fukushima disaster)," he said in 2011. Tokyo last hosted the Games in 1964.
人氣非常高的一個建議是，可以再次使用東京當年申辦奧運會時使用的標識。申辦標識由設計專業的學生島峰藍設計，標識上有一個櫻花花環。2011年，日本奧委會主席竹田恒和表示，這個櫻花花環象征著回歸，在這里有兩層意思，“奧運圣火能再次回到日本，日本能從福島災難的創傷中復原。”東京上次舉辦奧運會時在1964年。

One of the idea being most widely shared on social media is a logo of a fan designed by illustrator Kan Kan. The designer said the fan represented good luck and is traditionally used for cheering, adding: "With this fan I am expressing many people's support for Japan."
社交媒體上轉發量最高的建議是插畫師Kan Kan設計的日本和扇標識。設計者表示，和扇象征著好運，是傳統的加油喝彩之物，“通過這樣的和扇設計，我道出了許多人對日本的支持。”
