The short answer
A Japanese company sold tire-valve parts to a Taiwanese tube maker, knowing some finished tubes would be sold in California. When a motorcycle crash in California led to a lawsuit there, the Taiwanese company tried to pull the Japanese supplier into the case. In Asahi Metal Industry Co. v. Superior Court, 480 U.S. 102 (1987), every Justice agreed California could not exercise jurisdiction over the supplier, and eight agreed that doing so would be "unreasonable and unfair." What they could not agree on is the question students remember the case for: whether putting a product into the "stream of commerce," aware it will reach a state, counts as a minimum contact with that state.

| Citation | 480 U.S. 102 (1987), No. 85-693 |
| Court | Supreme Court of the United States, on review from the Supreme Court of California, 39 Cal. 3d 35 (1985) |
| Argued / decided | November 5, 1986 / February 24, 1987 |
| Judgment | Reversed and remanded; no Justice voted to uphold jurisdiction |
| Majority holding | Part II-B (8 Justices): exercising jurisdiction over Asahi would be unreasonable and unfair under the Due Process Clause |
| Open question | Whether awareness that a product will reach the forum through the stream of commerce is enough for minimum contacts (Court split 4–4) |
Who joined what: reading a fractured decision
Asahi is a case where you have to track the votes part by part. Justice O'Connor announced the judgment, but only some parts of her opinion drew five or more votes.
| Opinion / part | Joined by | Votes | What it says |
|---|---|---|---|
| O'Connor, Part I | All Justices | 9 | The facts and procedural history |
| O'Connor, Part II-A | Rehnquist, Powell, Scalia | 4 | Stream of commerce plus: awareness alone is not purposeful availment |
| O'Connor, Part II-B | Rehnquist, Brennan, White, Marshall, Blackmun, Powell, Stevens | 8 | Jurisdiction would be unreasonable and unfair (opinion of the Court) |
| O'Connor, Part III | Rehnquist, Powell, Scalia | 4 | No minimum contacts; reverse |
| Brennan, concurring in part and in the judgment | White, Marshall, Blackmun | 4 | Agrees with II-B; awareness is enough for minimum contacts |
| Stevens, concurring in part and in the judgment | White, Blackmun | 3 | II-B decides the case; II-A was unnecessary and misapplied |
Two points trip students up. First, Justice Scalia joined Part II-A but not Part II-B, which is why the fairness holding has eight votes rather than nine. Second, Justices White and Blackmun joined both the Brennan and the Stevens opinions, so counting "sides" on stream of commerce gives you 4 (O'Connor) versus 4 (Brennan), with Stevens declining to choose.
Facts: from a valve factory in Japan to a highway in California
On September 23, 1978, Gary Zurcher lost control of his Honda motorcycle on Interstate 80 in Solano County, California. He was severely injured, and his wife, Ruth Ann Moreno, who was riding as his passenger, was killed. Zurcher sued in California state court, claiming the rear tire, tube, and sealant were defective. One defendant was Cheng Shin Rubber Industrial Co., the Taiwanese maker of the tube.
Cheng Shin filed a cross-complaint seeking indemnity from Asahi Metal Industry Co., the Japanese company that made the tube's valve assembly. Zurcher's own claims later settled, which left only Cheng Shin's indemnity claim against Asahi.
| Link in the chain | What the record showed |
|---|---|
| Asahi (Japan) | Made valve assemblies in Japan; sold them to Cheng Shin and other tire makers. Sales took place in Taiwan, with shipments from Japan to Taiwan. |
| Volume | 150,000 assemblies in 1978; 500,000 in 1979; 500,000 in 1980; 100,000 in 1981; 100,000 in 1982 |
| Importance to Asahi | Sales to Cheng Shin were 1.24% of Asahi's income in 1981 and 0.44% in 1982 |
| Cheng Shin (Taiwan) | Sold finished tubes worldwide; alleged that about 20% of its U.S. sales were in California |
| California | Asahi had no office, agents, employees, or property there, and did not advertise or solicit business there |
Asahi's president declared that Asahi "has never contemplated that its limited sales of tire valves to Cheng Shin in Taiwan would subject it to lawsuits in California." Cheng Shin, for its part, pointed to evidence that tubes with Asahi valves were sitting on California store shelves.
How the case reached the Supreme Court
Asahi moved to quash Cheng Shin's service of summons, arguing that California could not exercise jurisdiction over it consistent with the Due Process Clause of the Fourteenth Amendment. California's long-arm statute reaches as far as the Constitution allows, so the only question was constitutional.
The Superior Court denied the motion. The California Court of Appeal ordered the summons quashed. The Supreme Court of California reversed, holding that Asahi's intentional act of placing its valves into the stream of commerce, combined with its awareness that some would reach California, was enough. The U.S. Supreme Court granted certiorari and reversed.
The two questions, and how the Court answered each
The competing stream-of-commerce tests
Stream of commerce plus (O'Connor, for four)
"The placement of a product into the stream of commerce, without more, is not an act of the defendant purposefully directed toward the forum State."
The "more" can include "designing the product for the market in the forum State, advertising in the forum State, establishing channels for providing regular advice to customers in the forum State, or marketing the product through a distributor who has agreed to serve as the sales agent in the forum State."
Pure stream of commerce (Brennan, for four)
"The stream of commerce refers not to unpredictable currents or eddies, but to the regular and anticipated flow of products from manufacture to distribution to retail sale."
"As long as a participant in this process is aware that the final product is being marketed in the forum State, the possibility of a lawsuit there cannot come as a surprise."
The volume approach (Stevens, for three)
Whether conduct rises to purposeful availment "is affected by the volume, the value, and the hazardous character of the components." Stevens added: "In most circumstances I would be inclined to conclude that a regular course of dealing that results in deliveries of over 100,000 units annually over a period of several years would constitute “purposeful availment,” even though the item delivered to the forum State was a standard product marketed throughout the world."
The heart of the disagreement is one sentence from Part II-A: "a defendant's awareness that the stream of commerce may or will sweep the product into the forum State does not convert the mere act of placing the product into the stream into an act purposefully directed toward the forum State." Applying that test, O'Connor's plurality found no purposeful availment, because Asahi did not create, control, or employ the distribution system that brought its valves to California. Brennan's group would have found minimum contacts based on Asahi's regular and extensive sales to a manufacturer it knew was selling in California.
The fairness test that actually decided the case
Part II-B applied the reasonableness factors from World-Wide Volkswagen. "A court must consider the burden on the defendant, the interests of the forum State, and the plaintiff's interest in obtaining relief. It must also weigh in its determination “the interstate judicial system's interest in obtaining the most efficient resolution of controversies; and the shared interest of the several States in furthering fundamental substantive social policies.”"
| Factor | Applied to Asahi |
|---|---|
| Burden on the defendant | Severe. Asahi would have to litigate across an ocean and submit its dispute with Cheng Shin to a foreign judicial system. |
| Forum State's interest | Slight. Cheng Shin was not a California resident, and the remaining claim was about indemnity, not consumer safety. |
| Plaintiff's interest in relief | Slight. Nothing showed California was more convenient for Cheng Shin than Taiwan or Japan. |
| Efficient resolution | Not separately weighed; the Court's analysis turned on the burden and the weak interests on the other side. |
| Shared policies (here, international interests) | Courts must consider the interests of other nations and the federal government's foreign relations when reaching a foreign defendant. |
Two lines from Part II-B are worth knowing. On burden: "The unique burdens placed upon one who must defend oneself in a foreign legal system should have significant weight in assessing the reasonableness of stretching the long arm of personal jurisdiction over national borders." On the bottom line: "Considering the international context, the heavy burden on the alien defendant, and the slight interests of the plaintiff and the forum State, the exercise of personal jurisdiction by a California court over Asahi in this instance would be unreasonable and unfair." The Court also noted that the remaining dispute was mainly about indemnification, not the safety of consumers.
Where Asahi came from, and where the question went
| Case | Defendant and forum | Result | Stream-of-commerce takeaway |
|---|---|---|---|
| World-Wide Volkswagen (1980) | New York car dealer and regional distributor; Oklahoma | No jurisdiction | Delivering products with the expectation they'll be bought in the forum can support jurisdiction |
| Asahi (1987) | Japanese component maker; California | No jurisdiction (unreasonable) | Split 4–4 between "plus" and "pure" stream of commerce |
| J. McIntyre v. Nicastro (2011) | English machine maker; New Jersey | No jurisdiction | Plurality requires targeting the forum; still no majority test |
| Goodyear v. Brown (2011) | Foreign tire subsidiaries; North Carolina | No general jurisdiction | Stream of commerce supports specific jurisdiction only |
How Asahi shows up on exams
Asahi is the case to cite whenever a fact pattern has a manufacturer (often a foreign one) that sells to a middleman, with the product ending up in the forum through someone else's distribution network. Professors use it to test two skills: running the stream-of-commerce analysis when there is no majority rule, and doing the fairness analysis as a separate step.
For minimum contacts, apply both tests and say whether the answer changes. Under O'Connor's test, look for the "plus" factors: forum-specific design, advertising, customer service, or a forum sales agent. Under Brennan's test, ask whether the defendant knew the product was regularly marketed in the forum. Mention Stevens's volume point when the numbers are large, and note that McIntyre's plurality took the stricter view without settling the question.
For fairness, walk through the factors and compare the facts to Asahi. Asahi's facts were extreme: a foreign defendant, a foreign plaintiff, and a leftover indemnity claim. When an injured forum resident is suing, the forum's interest is much stronger, and fairness is far less likely to defeat jurisdiction. If the defendant is subject to jurisdiction but the forum is inconvenient, consider venue transfer and forum non conveniens as separate tools.
Don't stop at personal jurisdiction. A complete answer also confirms the court has subject-matter jurisdiction, since the two are independent requirements.

Frequently asked questions
What was the outcome of Asahi Metal Industry Co. v. Superior Court?
The Supreme Court reversed the California Supreme Court and held that California could not exercise personal jurisdiction over Asahi. No Justice voted to uphold jurisdiction. Eight Justices agreed that exercising jurisdiction would be unreasonable and unfair under the Due Process Clause.
Was Asahi a plurality opinion?
Partly. Part II-B, holding that jurisdiction would be unreasonable, was an opinion of the Court joined by eight Justices. Part II-A, which set out the stream-of-commerce-plus test, was joined by only four Justices, so it is a plurality opinion. Justice Brennan wrote for four Justices who rejected it, and Justice Stevens wrote for three who found it unnecessary.
What is the stream of commerce plus test?
It is Justice O'Connor's test from Part II-A of Asahi. Placing a product into the stream of commerce, even knowing it will reach the forum, is not enough. The defendant must also do something aimed at the forum, such as designing the product for that market, advertising there, setting up customer service there, or using a forum sales agent.
Is stream of commerce enough for personal jurisdiction?
The Supreme Court has never settled this. In Asahi, four Justices said awareness is not enough and four said it is. In J. McIntyre Machinery v. Nicastro (2011), a four-Justice plurality required that the defendant target the forum, but again there was no majority. Goodyear v. Brown (2011) held that the stream of commerce cannot support general jurisdiction.
When was Asahi decided?
Asahi was argued on November 5, 1986, and decided on February 24, 1987. The citation is 480 U.S. 102 (1987).
Why did the Court find jurisdiction unreasonable in Asahi?
The burden on Asahi, a Japanese company forced to defend in a foreign legal system, was severe. California's and Cheng Shin's interests were slight, because Zurcher's claims had settled and all that remained was an indemnity dispute between two foreign companies about a sale made in Taiwan.
