Japan has had frequent exchanges with Taiwan, but when it put on the Aichi World Expo in 2005 it was only able to permit "back-door" participation from Taiwan via the "Ilha Formosa" restaurant, which offered various culinary delicacies and produce from the island. A formal pavilion, like those of other nations, was not possible.
即使與台灣交流頻繁的日本，當 2005 年舉辦愛知博覽會時，也僅准允台灣藉著開設「ILHA FORMOSA」（美麗之島）餐廳的方式「藏身」會場，推介美食及農特產，而無法像其他國家般籌備正式展館。
