MUG-JP Space Revival

We’ve revived MUG-JP Space, which we held monthly in 2023. After writing the 2024 summary, we held seven sessions in total, one each month. Previously, it was only live, but starting this year, we’re archiving episodes as podcasts. Please give them a listen. We’ll be taking a break again starting in August…
