Dispute Resolution Specialists

Who We Are

Japan Chambers is made up of individual lawyers with expertise in dispute resolution.  All our Members are fluent in both English and Japanese and able to act as counsel,  arbitrator or mediator.


Japan Chambers is not a firm, nor are its member partners or employees. Though Japan Chamber Members are self-employed or connected to independent law firms, in most cases, they may be instructed individually or in a team to provide a wide range and level of expertise in both contentious and non-contentious work.



Arbitration is an adjudicatory process in which a neutral third party(s) is empowered to render a final and binding decision after hearing all of the evidence, arguments, and proof of the disputing parties. Some arbitration clauses provide for the appointment of two party-appointed Arbitrators and a third neutral Arbitrator appointed by those two. Other arbitration clauses provide for the appointment of one or three neutral Arbitrators. Arbitration is binding in virtually all contractual arbitration settings and in a limited number of cases is advisory in nature. Many contracts provide for binding arbitration as the sole and exclusive remedy available to the parties.

High-Low Arbitration is an adjudicatory process in which the parties set a minimum and maximum range for the Arbitrator's decision. If the final award comes in above the maximum or below the minimum range the award is automatically adjusted to the maximum or the minimum figure. If the Arbitrator's award falls in between the two figures that figure becomes the exact amount awarded. In some cases the Arbitrator is advised of the parties' high-low agreement and in other cases the high-low arrangement is not disclosed to the Arbitrator viewing the matter with the parties each party submits a final offer. The neutral must chose the higher (or lower as the case may be) as the most reasonable.

Mini-trial is a settlement process which involves the presentation of a highly summarized case by the parties to three member panel comprised of a senior official from each party (with full settlement authority) and a neutral chairperson. Following the case presentations, the neutral chairperson convenes a private caucus with the two senior company officials in an effort to mediate or render a non-binding recommendation.

Mediation-Arbitration is a hybrid process in which the parties attempt to resolve a dispute with the assistance of a trained Mediator and, in the absence of a final resolution, agree to have the Mediator act as an Arbitrator with binding decision-making authority. In some cases the Mediator/Arbitrator's authority is limited to the final settlement offers of the parties and in other cases the Mediator/Arbitrator may fashion any remedy he/she deems appropriate.


Mediation involves using a trained neutral third party to assist disputing parties to bring about a mutually acceptable resolution of an existing dispute. The Mediator convenes joint and separate meetings with the parties to explore interests, needs, positions, and potential solutions. Mediators do not have the authority to compel a decision; resolutions must be reached and agreed to by the parties themselves.


Neutral Evaluation is a non-binding process which utilizes a neutral fact-finder who evaluates the merits of the parties' positions. After the parties have submitted written position statements and supporting exhibits, the neutral evaluator convenes a brief, informal hearing to hear an abbreviated version of each party's case. Thereafter, the neutral provides the parties with an objective and confidential assessment of their positions. The neutral's written assessment can serve as a valuable tool for further negotiations between the parties.


Using highly experienced business profesionals rather than lawyers, neutrals can assist in dealing with intra company conflicts by providing guidance and experience.


Negotiated Rulemaking provides an alternative methodology for drafting proposed regulations. Agency representatives and affected interest groups use the services of a neutral facilitator to negotiate rule drafting and implementation procedures.

Final Offer Arbitration (also referred to as "Baseball Arbitration") is an adjudicatory process in which the Arbitrator(s) is empowered to choose between the final settlement positions offered by the parties. In final offer arbitration the Arbitrator(s) convene hearings, consider evidence and proofs from the parties, and thereafter, render a final decision which awards one or the other of the final positions offered by the parties.


Arbitration-Mediation is sometimes referred to an "envelope" mediation. After hearing the parties and preparing an award, the arbitrator places the award in an envelope and, as his or her role as an arbitrator has been fully discharged, reconvenes the parties and asks them to consider whether they would like the former arbitrator to attempt to mediate the dispute. The process is completely voluntarily and, if during the course of the mediation, either party or the mediator considers that no progress towards settlement is being made, the mediation is terminated and the parties open the envelope which contains the arbitral award.
