Sakata Co., Ltd. and Mond Co., Ltd. (both based in Matsue, Shimane) will host 'All-Night EXPO Sakaba at Shimane featuring Izumo/Matsue' on June 5–6, 2026, at the Yunokawa Onsen Koseiso in Izumo City.
This all-night co-creation event brings together a diverse group—from youth to veterans, and business owners to creators—to bring their challenges and questions for discussion until dawn in an onsen setting. It is not a one-way lecture but an overnight experience designed to spark new initiatives within spaces like the 'Japan's Top 3 Beautiful Skin' hot springs, a specially installed sauna bus, and a 'snack bar street' filled with neon lights and a bar-like atmosphere.
In the daytime, optional fieldwork will take participants to sites of innovation in Shimane, connecting the energy and insights gained there to the nighttime dialogue.
**Event Overview**
- **Name:** All-Night EXPO Sakaba at Shimane featuring Izumo/Matsue
- **Date:** June 5 (Fri) 12:00 PM – June 6 (Sat) 8:00 AM (All-night)
- **Venue:** Yunokawa Onsen Koseiso (1948 Gakutou, Hikawa-cho, Izumo-shi, Shimane)
- **Capacity:** Approx. 100 participants
- **Details:** https://exposakaba-shimane.studio.site/
**Background and Objectives**
Having worked on many real estate renovations, the organizers realized that while physical improvements make places cleaner and more convenient, they sometimes lose their original value or unique charm. This led to the concept of 'renovation without renovating'—generating new value by changing how a place is used and who gathers there, rather than changing the building itself.
Koseiso is the embodiment of this philosophy. By changing the usage and people at this ordinary Izumo inn, new encounters and dialogues give the space entirely different meanings. The event proposes updating the 'meaning' of a space as a new form of development.
**Four Key Features**
1. **Koseiso Experience:** Featuring source-fed hot springs and a special sauna bus to facilitate open-hearted discussions.
2. **All-Night 'Leeway':** Unlike daytime events, the overnight format allows for a cycle of discussion, small talk, hot springs, sauna, dining, and sleep, where honest opinions emerge at late hours.
3. **Snack-Bar Style Space:** Multiple spaces themed like 'snack bars' (Japanese neighborhood bars) allow for free-flowing, fluid dialogue based on interest themes.
