> 当事者の数が二人であり、仲裁人の数が三人である場合において、前項の合意がないときは、当事者がそれぞれ一人の仲裁人を、当事者により選任された二人の仲裁人がその余の仲裁人を、選任する。この場合において、一方の当事者が仲裁人を選任した他方の当事者から仲裁人を選任すべき旨の催告を受けた日から三十日以内にその選任をしないときは当該当事者の申立てにより、当事者により選任された二人の仲裁人がその選任後三十日以内にその余の仲裁人を選任しないときは一方の当事者の申立てにより、裁判所が仲裁人を選任する。

English (Japanese Law Translation, Ministry of Justice):

In this case, if one party fails to appoint an arbitrator within 30 days from the day on which it received a request for appointing an arbitrator from the other party that has already appointed an arbitrator, the court will appoint the arbitrator upon the petition of that other party, and if the two arbitrators appointed by the parties fail to appoint the third arbitrator within 30 days from their appointment, the court will appoint the arbitrator upon the petition of one of the parties.
