共同社报道，该法律允许“符合条件的道府县申请指定”。它旨在确保在发生大规模灾害时国家和社会职能的连续性，以及将经济活动从世界第四大经济体的首都圈分散出去。
The law allows “eligible prefectures to apply for designation,” Kyodo News reported. It allows for the continuity of national and social functions in case of a large-scale disaster, as well as the decentralization of economic activities away from the capital region of the world’s fourth-largest economy.
该法律的出台，是执政联盟合作伙伴日本维新会寻求将其在西日本的核心基地大阪建设成像东京一样的大都市之际实现的。
The law came to fruition as the ruling coalition partner, the Japan Innovation Party, seeks to turn Osaka, its core base in western Japan, into a metropolis like Tokyo.
报道称，“预计政府将于11月公布关于备都地位的基本方针及指定时间表。”
“The government is expected to announce in November its basic approach to second capital status and a timetable for its designation,” the report said.
根据新法律，当局将给予获指定为副首都地区税收优惠以促进投资。该法还允许首相根据道府县的申请指定备都。
Authorities will grant tax incentives to boost investment in areas designated as secondary capitals under the new law. It also allows the prime minister to designate a backup capital based on applications from prefectures.
报道补充称，“该法未将副首都数量限定为一处，留有多个道府县获指定的可能性。”
“It does not limit the number of second capitals to one, leaving open the possibility that multiple prefectures could be designated,” the report added.
预计至少有四个道府县——北部的北海道、中部的爱知县、西南部的大阪府和福冈县——将申请备都地位。
At least four prefectures — Hokkaido in the north, Aichi in central Japan, Osaka and Fukuoka in the southwest — are expected to apply for alternate capital status.
首相高市早苗领导的政府上周二批准了一项命令，设定了获得该地位的要求，包括该道府县占日本国内生产总值（GDP）至少2.1%，且拥有至少占全国人口1.2%的城市。
The government of Prime Minister Sanae Takaichi approved an ordinance last Tuesday setting requirements for gaining the status, including that a prefecture account for at least 2.1% of Japan's gross domestic product and contain a city with at least 1.2% of the country's population.
