The new legislation will enable Japan to catch up with the European Union and the United Kingdom in regulating IT giants and is expected to help weaken their grip on the market. The Japan Fair Trade Commission will proceed with building an appropriate competition environment in the digital market by increasing the number of personnel engaged in the field.

The government aims for the bill’s passage during the current Diet session. But Apple is poised to block its passage, intensifying its lobbying of lawmakers in both the ruling and opposition parties.

Rapid decomposition and detoxification of plastics after use are significant challenges. As a possible solution, biodegradable plastics have attracted attention, and for environmental risk assessment research on polymer toxicity, use of indicator organisms, like water fleas and fish, has increased globally.
