The American stainless-steel bottle brand Hydro Flask (ハイドロフラスク) will hold the special pop-up "omomuki lounge by Hydro Flask" for five days only, from Wednesday, November 25 to Sunday, November 29, 2026. The venue is the Bunshokan (文書館) on the grounds of Dazaifu Tenmangu in Dazaifu City, Fukuoka Prefecture.
The event presents an installation space inspired by the Japan-exclusive "omomuki (趣)" collection, which draws on traditional Japanese beauty and colors. For worshippers and tourists who have walked around the spacious grounds, the lounge lends out the slim "Micro Hydro (マイクロハイドロ)" bottle, which slips easily into a pocket, free of charge. Visitors can then rest slowly on the veranda (縁側) with freshly brewed hot tea.
The event also includes a collaboration with Kasanoya (かさの家), which makes and sells Dazaifu's specialty Umegae mochi (梅ヶ枝餅).
Background: A Sustainable Autumn Break Carrying omomuki
One of Hydro Flask's missions is "Cut Loose Single Use," which aims to move away from disposable plastic. The event grew out of a wish to create a resting place for tourists and worshippers who are a little tired from walking around the vast grounds and approach of Dazaifu Tenmangu. Surrounded by the world of the omomuki collection, which comes in traditional Japanese colors (matcha 抹茶, karashi 芥子, and akane 茜), visitors can take a breather in body and mind.
Rather than simply displaying and selling products, the event lets visitors pick up the bottles and feel the temperature and mouthfeel for themselves. The aim is to suggest how pleasant it is to carry your own bottle when you travel.
What to Experience at the Lounge
