Hello Kitty from Sanrio is collaborating with Hobonichi Techo 2027, releasing 17 types of planners and stationery items on September 1, 2026 at 11:00 AM. The designs use the popular Hello Kitty Classic style from the 1970s, with poses exclusive to Hobonichi Techo. The Original size (A6) and Cousin size (A5) planner covers feature Kitty playing with or reading her planner, surrounded by ribbons, apples, and her friend Joey. The weeks weekly planner uses a necktie fabric weave to express Hello Kitty's playful poses, such as sitting neatly to read or putting the planner over her face. Other items include protective covers, the upright storage pouch stappo, the flat pen case comodo, clear files, writing boards, stickers, stamps, and sticky notes. Sales channels include the Hobonichi online store, TOBICHI direct-run stores in Tokyo and Kyoto, Loft stores nationwide, Amazon, and Rakuten.
