Japan Post shipping weight limit France?

JP web English site states that the max weight per box (for sea/surface shipping) is 30kg but can differ in some countries.

Can anyone help me find the actual weight limit for France? I don't want to start packing, haul boxes to JP, then find out I made a mistake.

Thanks!

Though I can't find the information in English, their Japanese page says it's 30 kg.

That's EMS. I posted 'by sea/surface'.

According to these information pages, the limits of both the international parcel sending and the EMS are the same.
