TOKYO, Nov 25 (Reuters) - Benchmark Tokyo rubber futures rebounded from the previous day's loss on Wednesday as surging Shanghai futures and higher overnight oil prices lent support, although gains were capped below a key 160 yen ceiling due to nagging worries about oversupply, dealers said.

It fell more than 3 percent the previous day.
