A quiet revolution is sweeping through Japan's travel culture. In a country where 1 in 5 travelers now prefers to go solo, the highest rate among 39 nations surveyed, a new movement called "Suitcase Cancel" is gaining traction: ditch the rolling luggage entirely and travel with just a backpack.

Japan: The World's #1 Solo Travel Nation

According to a 2024 survey by Euromonitor International, 19.2% of Japanese respondents said they "usually travel alone on vacation," the highest among 39 countries surveyed. The global average was just 7.2%. More striking still, this figure has nearly doubled from 10.4% in 2019, a shift largely attributed to the COVID-19 pandemic's impact on social attitudes.

Japan's Tourism Agency data confirms the trend, showing that solo trip participants have increased by approximately 2.5 million compared to pre-pandemic levels. The Jalan Research Center's 2025 domestic travel survey found "solo travel" at 18.0%, making it the second most common travel companion type after "couple travel" (25.6%). Among men aged 18–29 and those in their 50s, solo travel was actually the top choice.

Several cultural factors explain Japan's solo travel boom. Japanese society has long embraced "Ohitorisama" culture, the socially accepted practice of dining, shopping, and traveling alone. Services catering to solo customers, from single-seat ramen counters to solo karaoke booths ("Hitori Karaoke"), have been commonplace for years. The pandemic accelerated a shift from collectivist priorities toward self-care and individual fulfillment, particularly among the 30–44 age group.

Smartphone technology has been a key enabler. With bookings, payments, navigation, and real-time translation all available on a single device, the practical barriers to solo travel have largely vanished.

The "Locker Refugee" Problem: Luggage Getting in the Way

As the number of solo travelers grows, the problem of "locker refugees" (locker nanmin) at tourist spots and major stations has worsened. Locker refugees are travelers who can't store their bags because the coin lockers are full.

At Japan's major terminal stations, it has become routine for coin lockers to fill up early in the morning during busy periods. A JR East official acknowledged that "at Tokyo Station during busy seasons, the coin lockers fill up early in the morning." A TBS report cited an estimate that more than 170,000 people a day become locker refugees.

The surge in inbound tourists makes it worse. The number of foreign visitors to Japan hit a record level in 2024, and overseas travelers with large suitcases are occupying the large lockers in many places. Kyoto Station introduced "Eki-Suma," a real-time locker availability service, and JR East offers "To Locca," an advance booking service for lockers, but railway companies have not found a fundamental solution.

New services such as the luggage-sharing platform ecbo cloak, which turns spare space in cafes and hotels into luggage storage, have also appeared, but 70% of users are foreigners and 90% of the bags stored are suitcases. In other words, the root of the locker refugee problem is the suitcase itself, a large piece of luggage.

The New Idea of "Suitcase Cancel"

Out of this situation came the idea of "suitcase cancel." It is not simply about packing less, but an active strategy of rethinking the suitcase-based style of travel and completing a trip with a single backpack.

The essence of suitcase cancel is not subtraction but conversion: turning the time and mobility lost to dragging a suitcase into experiences and freedom.

Think about it. A suitcase creates a surprising amount of lost time: wandering stations looking for a locker, hauling it up stairs and escalators, awkwardness on crowded trains, waiting at the baggage carousel. In a country like Japan, where travel revolves around trains, the stress of wheels catching on cobblestones and unpaved paths can't be ignored either.

Those practicing suitcase cancel are mainly active travelers in their 30s to 50s. In an age when a single smartphone handles booking and payment, the sense that "only our luggage has been left behind, heavy and bulky" is driving the movement.

Why an Ordinary Backpack Won't Do

But it isn't as simple as "then just take an ordinary backpack." Many travelers who have tried giving up the suitcase run into the limits of existing backpacks.

Ordinary backpacks are packed from the top, so items at the bottom are hard to reach. Even neatly folded clothes get jumbled on the move, leaving you wearing wrinkled clothes at your destination. And carrying a heavy load for long periods strains the shoulders and back, sapping the energy you need for the trip.

To meet these challenges, a new generation of travel backpacks combining the organization of a suitcase with the mobility of a backpack has begun to appear. Some open 180 degrees like a suitcase, some have a square shape that eliminates dead space, and some use back-panel designs that reduce strain on the body; backpacks billed as "made for travel" are gaining support through crowdfunding and other channels.

The Broader Trend: Minimal Travel

"Suitcase Cancel" is part of a larger cultural shift toward minimalism in Japan. The country that gave the world "Danshari" (the decluttering philosophy of discarding unnecessary possessions) and Marie Kondo's "KonMari Method" is now applying those same principles to travel.

According to a survey by solo travel media platform "Sorotori," the most active solo travel demographic is women in their 50s, with women aged 30–50 comprising 75.5% of solo travelers surveyed. These are busy professionals and parents who use minimal travel as a way to maximize limited vacation time.

Technology has made material reduction possible. High-performance fabrics mean lighter, smaller clothing. Digital guidebooks replace heavy paper ones. Mobile payments eliminate the need for cash and receipts. The physical "stuff" required for travel has shrunk dramatically, but many travelers' luggage habits haven't caught up.

Japan's infrastructure is adapting too. Smart lockers with IC card (Suica/PASMO) authentication, credit card-enabled vending lockers, disaster-response lockers, and hotel delivery services from station lockers are all expanding. But "Suitcase Cancel" takes a different tack: rather than waiting for infrastructure to solve the problem, travelers are solving it themselves by simply not creating the problem in the first place.

In a country where travel is often about the journey itself, from winding train rides through mountain valleys to spontaneous onsen stops, being unencumbered by heavy luggage isn't a sacrifice. It's an upgrade.

What about in your country? Are you a suitcase traveler or a backpack traveler? Is solo travel common where you live? Does your country have reliable luggage storage infrastructure like Japan's coin lockers?
