The Tokyo Metropolitan Government amended its rules on noise pollution on Wednesday in an effort to make it easier for nurseries to open in the capital, where the number of children yet to find a day care facility is the largest among all prefectures.

The amendment exempts noise made by preschool children from the municipality's environment-maintenance bylaw, which requires that noise not surpass specified levels.

The move comes on the same day that a nursery was supposed to open in the city's Meguro Ward. However, plans for that facility were suspended indefinitely due to opposition from local residents, who feared being disturbed by noise from the facility.
