## Facts

- Nihon System Wear K.K. (Nihon), a Japanese company, acted through its representative, Shūjin Tada.
- Kensuke Koo, a Japanese national residing in California, agreed with Tada/Nihon to obtain, restore, and sell antique automobiles.
- Tada was introduced to Koo through a mutual acquaintance, Suzuki, who communicated Tada’s offer to Koo.
- The agreement contemplated restoration work in the United States and shipment of the restored cars to Japan.
- Nihon (through Tada) paid Koo sums intended to cover the restoration and related costs.
- Koo did not deliver the restored cars to Japan as contemplated.
- Nihon sued Koo in Japan seeking return of the money paid (a contract-based monetary recovery).
- Koo moved to dismiss, arguing Japanese courts lacked international jurisdiction because he did not reside or have domicile in Japan and his performance occurred outside Japan.
- The trial court granted Koo’s motion and dismissed for lack of jurisdiction.
- Nihon and Tada appealed, and the appellate court reversed the dismissal.

## Issues

1. Whether Japanese courts may exercise international jurisdiction over a California-resident defendant in a contract dispute involving restoration and sale of antique cars.
2. Whether the contractual obligation to ship/deliver the restored cars to Japan makes Japan a place of performance sufficient to support jurisdiction.
3. Whether, in determining the place of performance, the court should focus on the contract’s main obligation (delivery to Japan) rather than preparatory acts (acquisition/restoration abroad).

## Decision

- The trial court dismissed the action for lack of international jurisdiction.
- The Tokyo High Court reversed, holding that Japanese courts had international jurisdiction over Koo.
- The court treated the agreement’s contemplated shipment/delivery of the restored automobiles to Japan as a strong connecting factor supporting jurisdiction in Japan.

## Legal Principles

- In contract cases, Japanese courts may base international jurisdiction on a meaningful connection between the dispute and Japan, including where contractual performance is to occur.
- The “place of performance” for jurisdictional purposes can be identified by focusing on the contract’s principal performance obligations, not only where preparatory work is carried out.
- When a contract requires delivery or shipment into Japan, that delivery obligation can support jurisdiction in Japan even if substantial work occurs abroad and the defendant resides outside Japan.

## Conclusion

Nihon System Wear K.K. v. Kensuke Koo holds that Japanese courts could hear Nihon’s claim to recover funds paid under an agreement to restore and supply antique cars because the contract called for shipment/delivery to Japan, making Japan a sufficiently connected place of performance for international jurisdiction despite the defendant’s residence in California.
