A hands-on 'build day' and hackathon-style event inspired by the Slush Helsinki women's hackathon, brought to Tokyo. The event empowers women and non-binary creators to build AI-coded products without prior technical experience. Participants will use tools like Lovable and Cursor to turn business ideas, side projects, or dream products into working prototypes. The day includes welcome remarks from the Embassy of Finland, inspirational stories from female builders, a live 'vibe coding' demo, a hands-on building session, and a showcase with judging and prizes. The event is hosted at Mercari's office and supported by various tech organizations to bridge the gap between design, technology, and entrepreneurship.
