Why Do Competing Stores Open Right Next to Each Other?
1. Conclusion
AOKI and Yofuku-no-Aoyama are not part of the same corporate group. AOKI belongs to AOKI Holdings’ fashion business, while Yofuku-no-Aoyama is the core business-wear brand of Aoyama Trading; they are direct competitors. Kaikatsu CLUB, however, is operated by KAIKATSU FRONTIER within the AOKI Group, so AOKI and Kaikatsu CLUB do share a parent group. JOYJOY is not listed among AOKI Group businesses and competes separately with Kaikatsu CLUB.[1][2]
Yet it is common to see AOKI near Aoyama, Kaikatsu CLUB near JOYJOY, or McDonald’s surrounded by other restaurant chains. This is not simply a war of attrition. The main mechanism is that businesses targeting similar customers tend to rate the same locations highly. Proximity can intensify competition, but it can also create a commercial cluster where customers know they can compare several options in one trip.[8][9]
The best description is therefore competitive coexistence: rivalry and agglomeration benefits can exist at the same time.
2. Corporate relationships first
- AOKI vs Yofuku-no-Aoyama: different groups; direct competitors.
- AOKI vs Kaikatsu CLUB: same AOKI Group, but different business segments.[1]
- Kaikatsu CLUB vs JOYJOY: different groups; partially overlapping entertainment demand.[1][5]
- McDonald’s vs neighboring restaurant chains: usually unrelated companies competing for a broad set of meal occasions.
Physical proximity should not be confused with common ownership. In fact, unrelated competitors often cluster precisely because they are pursuing the same demand.
3. Why competitors open close to one another
Every retail format has a preferred location profile. Roadside businesses care about traffic volume, visibility, ease of entry and exit, parking capacity, population, household structure, nearby facilities, land cost, and day/night population. Station-front formats care more about passenger flows, pedestrian routes, office density, entertainment districts, and available floor area.
If two firms serve similar customers, independent analyses can lead both of them to the same bypass, intersection, or station district. That does not prove that one intentionally copied the other. Similar optimization criteria often produce similar answers.
A surviving incumbent can also provide useful market information: its presence suggests that some level of demand may exist. How much a specific chain incorporates competitor performance into its models is normally confidential, so this should be treated as a rational location-theory explanation rather than a claim about any company’s undisclosed playbook.
4. AOKI vs Yofuku-no-Aoyama: the clearest direct rivalry
Both companies grew through suburban menswear formats. Aoyama Trading opened what it describes as the industry’s first suburban menswear specialty store in 1974 and continued to emphasize suburban stores. Its current property criteria for Yofuku-no-Aoyama include freestanding stores, suburban conversions, building-in formats, and commercial complexes; freestanding stores are typically 120–150 tsubo with 15–25 parking spaces.[3][4]
AOKI opened its first standardized suburban store in 1979 and says officially that it developed primarily through roadside suburban chain stores. Today it also uses open malls, shopping centers, building-in locations, downtown areas, and stations.[2]
Because their ideal lot size, parking needs, car access, and catchment characteristics overlap, neighboring stores are structurally unsurprising.
The upside is comparison shopping. Customers buying suits often compare price, fit, silhouette, alterations, service, and promotions. A cluster can become known as “the place to shop for suits.” The downside is equally obvious: high substitutability makes price cuts, coupons, advertising, and assortment easy to compare. When the market contracts, rivalry can overwhelm the cluster benefit.
5. Kaikatsu CLUB vs JOYJOY: partial rather than total competition
These two formats overlap less completely. Kaikatsu CLUB combines manga, private rooms, internet access, rest, work/study use, and—depending on the store—karaoke or darts. JOYJOY centers on karaoke while also offering billiards, darts, table tennis, and other group entertainment. JOYJOY itself distinguishes suburban and station-front stores and operates both roadside locations with parking and urban locations.[5][6]
Their relationship is therefore best described as partial competition within the same leisure/nighttime catchment.
A customer who specifically wants karaoke can choose between them, but someone seeking solo manga reading, a private room, a nap, or temporary workspace leans toward Kaikatsu CLUB; a group seeking karaoke plus billiards or darts may lean toward JOYJOY. Because the use cases are not identical, both can survive in the same catchment more easily than two near-identical suit stores.
Entertainment districts also benefit from destination effects: when karaoke, restaurants, arcades, cinemas, and other activities cluster, consumers may visit the area simply because “there will be something to do.” Individual stores compete while the area collectively becomes more attractive.
6. Why McDonald’s is an especially strong example
McDonald’s is useful because its own materials explicitly describe systematic market analysis. Its store-development team evaluates market potential with specialized tools, then conducts on-site checks. Official property materials mention land shape, surrounding traffic, and nearby facilities among the factors examined.[7]
McDonald’s can also adapt its format to the site. Its disclosed property criteria identify three main formats:[7]
- Drive-through: arterial or local roads; typically 1,600 m² or more of land.
- Building-in: station areas, downtowns, and business districts.
- Food court: shopping centers and similar facilities.
That flexibility means McDonald’s is not dependent on a single kind of catchment. It can serve car-based, pedestrian, commuter, and mall traffic with different store configurations.
With a network of roughly 3,000 Japanese stores and high brand awareness, McDonald’s can also act as a destination in its own right. This does not mean neighboring businesses are guaranteed to succeed, but a major traffic-generating tenant can increase awareness and visitation for an area.
At McDonald’s scale, another problem becomes important: cannibalization between its own stores. A new outlet that merely shifts customers from a nearby McDonald’s may add little to company-wide sales. Large networks must optimize distance from both competitors and their own units.
7. Advantages of locating near competitors
Lower market-demand uncertainty. A functioning commercial cluster is evidence that the area supports some level of spending and traffic.
Easier comparison shopping. For suits, electronics, cars, furniture, and similar categories, customers value being able to compare multiple stores in one trip.
The area becomes a destination. Consumers learn “go there for suits,” “that road is full of restaurants,” or “that district is where we go at night.”
Defensive market share. A chain can prevent a rival from becoming the only major option in an attractive catchment.
5. Spillover awareness. A shopper visiting a competitor may notice another store and make an additional comparison visit.
8. Disadvantages and failure conditions
Direct sales dilution. If total demand is fixed, more stores mean less revenue per store.
Promotion and price wars. Easy comparison can increase discounting, coupons, and advertising costs.
Higher rents for prime sites. Multiple chains bidding for the same corridors can raise property costs.
4. Access problems. High traffic is not automatically good; medians, difficult turns, congestion, and poor entrances can reduce conversion.
- Overcapacity when demand shrinks. Population decline, weaker suit demand, or changes in leisure behavior can turn a once-rational cluster into excessive capacity.
6. Self-cannibalization. Large chains can steal from their own existing stores rather than from competitors.
9. Destructive rivalry or coexistence?
| Pairing | Demand overlap | Coexistence potential | Why |
|---|---|---|---|
| AOKI × Yofuku-no-Aoyama | High | Medium | Similar products and customers, but comparison-shopping benefits exist |
| Kaikatsu CLUB × JOYJOY | Medium | Relatively high | Same leisure catchment, different primary use cases |
| McDonald’s × other restaurants | Medium–high | Location-dependent | They fight for meals, but restaurant clustering can draw more visits |
| New unit × same-chain existing unit | Very high | Requires careful design | Cannibalization can simply transfer internal sales |
The real calculation is whether sales captured from rivals plus new demand created by the cluster exceed the profit lost through intensified competition.
10. How management theory explains it
Hotelling-style spatial competition. Firms targeting similar consumers may choose locations that converge rather than spread apart. Real cities are more complex than a one-dimensional model, but the key lesson remains: competition does not automatically produce physical separation.[8]
Huff/gravity-style store choice. Customers do not always choose the nearest store. Choice depends on a combination of attraction—size, brand, assortment, price—and travel cost.[8]
Agglomeration effects. Nearby retailers and services can raise the attractiveness and commercial efficiency of the area as a whole. Empirical research has found such effects in some retail categories, although the magnitude varies by industry.[9][10]
Cannibalization. A chain can expand unit count without expanding total company demand if new stores merely transfer sales from existing ones.
Difference from a dominant-area strategy. Competitor clustering is not the same as a chain deliberately saturating one region with its own stores. The latter is a deliberate concentration strategy designed to improve logistics, advertising, recognition, and management efficiency.
11. Summary
Seeing competitors next door can look irrational, but store development is a multi-variable optimization problem involving population, traffic, access, parking, rent, nearby facilities, comparison behavior, brand strength, store size, and existing units.
AOKI and Yofuku-no-Aoyama are separate groups, but their long history in similar roadside formats makes their preferred locations overlap. Kaikatsu CLUB and JOYJOY are also separate, yet they share leisure catchments while differentiating their core use cases, giving them more room to coexist. McDonald’s goes further by combining formal market analysis with multiple store formats for roadside, station, and shopping-center environments.
The core mechanism is not simply “build next to the enemy.” It is that independent companies searching for profitable locations can arrive at the same answer. If demand is large enough and the concepts are sufficiently differentiated, competitors can fight for customers while simultaneously strengthening the commercial district they share.
