This is the fourth year of JANTZEN's collaboration T-shirt fair with creators.
Every year, we collaborate with various individuals with unique personalities, and this time, we have asked two artists with distinctly different styles to draw illustrations related to JANTZEN, offering a total of four types of items.
They will be available in stores and online starting Wednesday, April 15.
The artist featured today is Nao Tatsumi. She is an artist active in a wide range of fields, drawing unique landscape paintings based on scenery collected from street corners and back alleys around the world while virtually traveling on maps.
Her work for this collaboration captures her unique view of Portland, the birthplace of JANTZEN. Please enjoy this special depiction of Portland, which is sure to be a statement piece this summer.
