Japan's Security Land Bill Enters Diet Debate on 10 November: Will the Permit System Reach Osaka?

The short version

A bill to amend Japan's Important Land Survey Act entered debate at a plenary session of the House of Representatives on 10 November. Its core is a prior-permission system, applied regardless of nationality, for acquiring land and buildings within about 1,000 m of certain defence facilities and in some other areas ^[4][2]. For anyone buying in Osaka, the key fact is this: according to the zone data published by the Cabinet Office, Osaka Prefecture currently has only four "monitored zones" and no "special monitored zone" ^[5][6], while the bill says the new "regulated zones" are to be designated from among special monitored zones ^[3].

Where the debate stands

The government submitted the bill to the 222nd extraordinary Diet session on 23 October ^[1]. According to the Sankei Shimbun, debate began at the lower house plenary on 10 November, with Kimi Onoda, the minister in charge of economic security, explaining the bill ^[4].

The government's main argument is that the current law only allows an order to stop improper use after the fact and cannot prevent the acquisition itself; because drones could be gathered in secret, prior notification and use restrictions alone are not enough, so the rules need to apply at the point of acquisition ^[4]. The same report says some opposition parties accept the security need but worry about property rights and economic activity, and one lawmaker asked about compensation when permission is refused. The government's position is that this is a minimal restriction owners should accept, so neither state purchase nor compensation is required ^[4].

What the bill changes

Based on the outline and summary of the bill published by the Cabinet Office, the main points are:

1. New "regulated zones". The area within about 1,000 m of facilities whose functions could be seriously disrupted, and hard to restore, by attacks such as secretly gathered drones (defence facilities with precision equipment such as fighter jets or radar, and Japan Coast Guard facilities) can be designated as a regulated zone. Uninhabited border islands are included too ^[2]. The bill summary states that regulated zones are designated from existing special monitored zones ^[3].

2. Prior permission for ownership transfers, with no minimum area. Transferring ownership of land or buildings in a regulated zone requires permission from the Prime Minister. A transfer without permission has no legal effect and will not be registered ^[2][3]. Permission will in principle be refused for foreign governments and their agencies, people engaged in foreign military activities, people obliged under foreign law to cooperate with them, and entities controlled by any of these. It will also be refused, regardless of nationality, where there are reasonable grounds to suspect the property would be used to damage facilities or gather intelligence ^[2].

3. Notification for mergers, changes of control and leases. A company that acquires land in a zone through a merger, or that falls under the refusal criteria because of a change in control, must notify the government and can be ordered to sell to a third party within one year; if it does not, the state will apply for a court auction. Leasing land in a zone requires notification after the fact ^[2].

4. Enforcement. Cabinet Office staff will be able to enter and inspect land in a zone, and the police may also inspect where needed ^[2]. According to press reports, an unpermitted transaction can be punished by up to three years' imprisonment or a fine of up to 3 million yen ^[4].

5. More important facilities. The Imperial Palace, the National Diet Building, the Prime Minister's Office and crisis-management government buildings will be added to the facilities covered by monitored zones ^[2]. The law would take effect on a date set by cabinet order within one and a half years of promulgation ^[2].

The existing system stays in place: transactions of land or buildings of 200 square metres or more in a special monitored zone still require prior notification ^[2].

The situation in Osaka

The Cabinet Office publishes monitored-zone maps by prefecture. Four important facilities are relevant in Osaka Prefecture: Camp Yao and Yao Airport (the zone covers parts of Osaka City, Yao, Matsubara, Kashiwara and Fujiidera), Camp Shinodayama (Izumiotsu and Izumi), the Nuclear Fuel Industries Kumatori plant (Izumisano and Kumatori) and the Ikoma radio relay station (Higashiosaka, plus Ikoma in Nara Prefecture) ^[5]. The zones are limited to the areas shown on the maps; they do not cover whole municipalities ^[5].

Meanwhile, Osaka is not among the 34 prefectures listed on the special monitored zone page ^[6]. Combined with the rule that regulated zones are designated from special monitored zones ^[3], it follows that if the bill passes in its current form and zone designations stay as they are, no regulated zone requiring permission would arise in Osaka Prefecture. The government could add or change designations later, however, so this should be checked against announcements at the time.

What this means for buyers in Osaka

First, typical condo purchases in central areas such as Umeda, Namba and Tennoji are outside the scope of this debate for now. The permit system applies only to regulated zones, Osaka currently has no qualifying special monitored zone ^[6], and nationality itself does not decide whether you can buy.

Second, if you are looking at property around Yao, Izumi, Kumatori or Higashiosaka, check the location first. The Cabinet Office's online map lets you check by address or lot number whether a property is in a monitored zone ^[7]. There is no notification duty for transactions in monitored zones, but land use there can be surveyed. Checking before you sign avoids questions later.

Third, corporate buyers and companies with foreign backing should watch the control rules. The bill brings entities effectively controlled by foreign governments into the refusal criteria and creates notification and forced-sale mechanisms for mergers and changes of control ^[2]. Even if this does not apply in Osaka yet, companies that own property elsewhere should keep an eye on it.

Fourth, the debate is still under way. The text may be amended in the Diet, and the law would take effect up to one and a half years after promulgation ^[2], so there is no need to rush a purchase or sale because of it.

Summary

The bill raises the rules around some important facilities from "notification" to "permission", regardless of nationality and with no minimum area ^[2]. In Osaka there are currently only four monitored zones and no special monitored zone ^[5][6], so the direct impact on most ordinary home buyers is limited. We will keep following the Diet debate and any new zone designations.
