China’s fury over Tokyo’s decision to discharge treated wastewater from the Fukushima nuclear plant is producing a rare beneficiary among Japanese stocks as tensions heighten.

Tobila Systems Inc., an Aichi-based developer of call-screening software for mobile phones, has seen its stock surge more than 10% since the water release on Aug. 24, a move that reportedly set off a torrent of angry calls from China to groups and individuals in Japan. Tobila, or “gate” in Japanese, announced Wednesday that it will offer a new feature for corporate customers that blocks overseas countries as the number of phone calls from China surges.
