The Tokyo Commodity Exchange (TOCOM) rubber contract for February delivery finished 4.9 yen, or 2.1 percent, higher at 233.5 yen ($2.15) per kg, after hitting the highest since May 24 of 234.7 yen earlier in the session. The most-active rubber contract on the Shanghai futures exchange for January delivery rose 300 yuan to finish at 17,570 yuan ($2,692) per tonne.
