It is well known that taking a bath improves creativity and problem solving. Archimedes found his Eureka moment in the bath. Hundreds of people came up with thoughtful ideas in the shower and posted to r/Showerthoughts every day. “72% of people get their best ideas in the shower.” Taking shower is known to contribute to increased dopamine flow and helps you become more relaxed, bringing you to the “creative sweet spot”.

Furthermore, taking bath makes you feel more fresh and energized. And it promotes good hygiene. Last but not least, the Onsen bath “promotes muscle pain relief, fatigue alleviation and blood circulation.”

Unfortunately, most offices don’t have Onsen baths. It is a problem that hinders and hampers productivity in workplaces around the world. Onsen.js is a lightweight informal gathering for people who would like to visit an onsen, socialize, and work remotely.

• So far, there have been 11 events. For the list, see Event list.

• Want to be a part of the next OnsenJS? See How to organize.

• For first timers: I know it can feel quite daunting to take a communal bath with people you’ve just met! Once you enter the premises, please feel free to proceed to the Onsen pools right away; no need to wait for anyone. We can get to know each other afterwards in the common area! Feel free to join and leave at any time. For example, I might stay until the place closes… or not, depending on situation.
