Experience the Pokémon Sleep fan event with a giant Snorlax, stamp rally, and sleepy Pokémon faces in Yokohama. Pokémon Sleep celebration awaits!
A Sleepy Spectacle Awaits in Yokohama
Imagine strolling into Yokohama’s Landmark Plaza and stumbling upon a colossal Snorlax, blissfully snoozing in the bustle of a shopping center. This isn’t just a fever dream for Pokémon fans—this July, it’s about to become delightfully real.

Just last month, Hello Kitty and friends graced Yokohama’s Minato Mirai with their own festival. Now, with the Sanrio crew having packed up, it seems the recently vacated spaces have become prime napping real estate for a different crowd: the Pokémon. The sleepy vibes are about to take over, and honestly, I’m not complaining.
Giant Snorlax: The Heart of the Pokémon Sleep Event
The main draw of the “Pokémon Sleeping Faces Research” event is, without a doubt, the gigantic Snorlax that will chill out in Landmark Plaza’s central atrium. There’s something both comical and oddly comforting about a massive, plushy Pokémon sprawled out in public, inviting passersby to pause and snap a photo—or maybe even yawn in solidarity.

This event marks the three-year anniversary of the Pokémon Sleep wellness app. Seeing Snorlax, the champion of all nap-takers, at the literal center of celebration seems on brand. I’ll admit, when I first heard about the event, I wondered if it might be too niche—could a giant dozing Pokémon actually draw a crowd beyond the diehard fans? But the more I think about it, the more it feels like the kind of playful whimsy that Pokémon does best.
Sleeping Pocket Monsters Everywhere
As you explore both Landmark Plaza and the neighboring Mark Is shopping center, keep an eye out—dozing Pokémon will be popping up all over the place. These sleepy displays are scattered throughout, transforming the malls into a treasure hunt of slumbering friends.




It’s easy to get swept up in the cuteness—at least until you start worrying you’ll miss one of the displays. I have to admit, tracking down every snoozing critter sounds more challenging than expected. My competitive streak is already tingling.
Join the Stamp Rally: Hunt for Sleepy Stamps and Prizes
Here’s where the event channels some classic Pokémon adventure spirit: the stamp rally. If you’ve never tried one, think of it as a scavenger hunt where your mission is to gather unique stamps from different locations in the two shopping centers.
There are six stamp stations in total—three at Landmark Plaza and three at Mark Is. Each station features different Pokémon and a unique stamp to add to your sheet.

“Pokémon Sleep’s Dr. Neroli stands ready to stamp your rally sheet.”

Collecting all six stamps earns you a special Pokémon Sleep sticker—assuming supplies last. I’m a little skeptical about the “while supplies last” caveat; in the past, I’ve missed out on event stickers because I arrived a day too late. Fingers crossed they’ve stocked up for the full run.

Mega Pokémon Gacha: Towels and More for the Lucky
No Pokémon event is complete without a little gacha action. Inside Landmark Plaza, you’ll spot a Mega Pokémon Gacha capsule toy machine, loaded with Pokémon Sleep-themed towels. Each spin costs 2,000 yen (about $12.50). That price initially made me pause, but the towels themselves come in various designs—Snorlax, plus Grass, Fire, and Water types.


The pricing feels a little steep for a towel, but the exclusive designs might just tip some wallets open. Would I be tempted? If the Snorlax towel is as plush as it looks, probably.
Shop for Sleepy Pokémon Merch at Mark Is
Shopping for Pokémon goodies is a time-honored tradition, and Mark Is steps up with its own Pokémon Sleep Shop. You’ll find keychains, acrylic figure stands, pins, pouches, and—perhaps most tempting—Snorlax cushions. There’s a surprising variety here, and I can’t help but feel a twinge of regret that my suitcase is always too small for the best plushies.


I tend to be wary of event-exclusive shops, as prices can sometimes feel inflated or stock limited. Still, the atmosphere is half the fun, and the selection looks genuinely impressive.
Sip on Real-World Pokémon Sleep Drinks
If merch isn’t your thing, the Pokémon Sleep Drink Stand at Mark Is offers a different kind of treat: real-life versions of in-game items like Mixed Juice, Lovely Kiss Smoothie, Craft Soda Pop, and Early Bird Coffee Jelly. Each drink order comes with one of six character coasters—a clever touch that makes even a simple refreshment a collectible.

Will these drinks taste as magical as their in-game counterparts? I’m not so sure—I’ve been burned before by event-themed drinks that look better than they taste. But I’m willing to be surprised, and the coasters are undeniably cute.
Nap Like a Pro: Try the Totone Nap Pod
Taking immersive to a whole new level, the fifth floor of Mark Is will feature a demonstration area for the Toyota-developed Totone nap pod, fitted out with Poké Ball flair just for the event. The idea of testing a high-tech nap pod in the middle of a bustling shopping mall is so wonderfully absurd that it almost feels like performance art.

I’m honestly torn here—part of me is eager to try it, and another part wonders if I could actually relax with a crowd of onlookers. Either way, it’s a memorable way to round out the Pokémon Sleep experience.
Event Dates and Final Thoughts
Pokémon Sleeping Faces Research runs from July 17 to August 23, transforming Yokohama into a haven for nap-loving trainers and sleepy Pokémon fans. And thanks to the extension of the city’s Pokémon mailboxes, you can tack on another quirky Pokémon stop while you’re in the neighborhood.
Event details, merch, and sleepy Pokémon galore—all packed into the heart of Yokohama’s shopping district. My initial skepticism about how engaging a “nap-themed” event could be has faded. Instead, I find myself oddly charmed by the blend of nostalgia, collectibles, and gentle whimsy. The only thing left to wonder: will the drinks and prizes live up to the Pokémon magic, or will they be a case of style over substance?
