Family-friendly Japanese language classes for our autumn trip to Tokyo?

Hey fellow travelers! I'm a parent planning a trip to Tokyo this November with my spouse and our two energetic kids, aged 8 and 10. We're excited to immerse ourselves in the local culture, but I'm a bit worried about communication barriers. Are there any family-friendly Japanese language classes or workshops in Tokyo where we can learn basic phrases and improve our language skills together? It'd be great to find something fun and engaging for the kids too, maybe with interactive activities or games. Any recommendations for language programs that cater to families with young children in a safe and welcoming environment? Thanks in advance for your help!
