I don't remember whether Japanese sex doll have foam cores. To solve this problem. Most doll manufacturers will use foam cores on the skeleton to expand the size of the doll and reduce the amount of silicone needed to make the doll. Some dolls have more bubbles than other dolls, but this is quite common practice. Yes, it is technically misleading to say that a doll is a "solid silicone" doll, but it is not honest. When I said that you don't want a really strong silicone doll. Please believe me, holding a large doll. I will answer your question about repairing Japanese sex dolls in another article later.
