あんなものを贈りたい こんなものを贈る自分が好きと思ったりして

We are making time to be "ufu"
We want to spread“ufu” all over the world.

What is ufu ?

You know the moments in which you find yourself smiling?
Maybe because you are holding something or using something special, Or when you are imagining the reaction of the person you’re choosing a gift for. Or maybe when you are pleased with the idea of yourself giving a gift. +lab’s goal is to add these little moments of smiling to your hectic everyday life.



+lab is Yamazakura’s consumer-oriented second brand

+lab products leverage the skills, know-how and networks built up by Yamazakura since its founding in 1931 as a general manufacturer of paper products for office use.

山櫻のショールーム サクラテラスで行われていた、女性だけのちいさな集まりがクラブ活動のようになり、プラスラボ誕生の種となりました。そんなちいさな種はブランドへと進化し、世界中の働く人の暮らしに寄り添う「『うふっ』となる時間」を届けることを目指す、山櫻のセカンドブランドとして活動しています。


The seeds from which +lab was born were planted by a small group of women who met at Yamazakura’s Sakura Terrace showroom as though engaged in some after-school club activity. Those small seeds evolved into Yamazakura’s second brand aimed at delivering “ufu” (happy) time to the world’s busy workers.
