Mortgages may be created, by an establishing act, in order to secure unspecified claims of a certain scope, up to the limit of a maximum amount.
抵当権は、設定行為で定めるところにより、一定の範囲に属する不特定の債権を極度額の限度において担保するためにも設定することができる。
The scope of the unspecified claims to be secured by the mortgage under the provisions of the preceding paragraph (referred to as "revolving mortgage" below) must be prescribed by limiting the scope to claims arising from specific contracts with the obligor for continuous transactions or other claims arising from certain kinds of transactions with the obligor.
前項の規定による抵当権（以下「根抵当権」という。）の担保すべき不特定の債権の範囲は、債務者との特定の継続的取引契約によって生ずるものその他債務者との一定の種類の取引によって生ずるものに限定して、定めなければならない。
Claims that arise continuously with the obligor pursuant to a specific cause, claims under negotiable instruments or checks, or electronically recorded monetary claims (meaning electronically recorded monetary claims prescribed in Article 2, paragraph (1) of the Electronically Recorded Monetary Claims Act (Act No. 102 of 2007); the same applies in paragraph (2) of the following Article) may be treated as claims that are to be secured by a revolving mortgage, notwithstanding the provisions of the preceding paragraph.
