We're excited to announce the teams selected for the first J-StarX Impact UK accelerator. Last week in Tokyo, we kicked off the programme to focus the next five weeks on supporting 12 Japanese tech for Good startups to leverage the combined connections, knowledge and network of our partner JETRO and BGV, and develop the best approaches to expand into the UK and European markets.

We are incredibly impressed with the cohort and the businesses they are scaling and cannot wait to see which companies will join us from this batch for an intensive three-month online programme and week-long boot camp in London in March.
