10 Japanese Kit Kats You Need to Try Before You Die (Seriously)

I have a confession: I'm obsessed with Japanese Kit Kats. It started innocently enough — a friend brought back a box of matcha-flavored Kit Kats from Tokyo. I thought, "How different can it be from the regular one?" Very different, it turns out. The matcha was earthy, slightly bitter, and perfectly balanced with the white chocolate. I was hooked. Over the past two years, I've ordered boxes online, begged friends to bring them from trips, and even tried making my own versions. Japan has over 300 Kit Kat flavors — seasonal, regional, and limited edition. I've tried about 50, and I'm nowhere near done. But I've identified 10 that stand out as truly exceptional. If you can find them, buy them. You won't regret it.

A note before we start: Japanese Kit Kats are different from the ones in the US or UK. The chocolate is creamier, the flavors are more nuanced, and the packaging is often beautiful. They're not just candy — they're little works of art. And because they're often sold in individual wrappers, they make perfect gifts. Now, let's get into the list.

1. Matcha (Green Tea) — The Classic

This is the gateway drug. Matcha Kit Kat is the most famous flavor, and for good reason. The chocolate is a white chocolate base infused with real matcha powder from Uji, Japan. It's not overly sweet — the matcha gives it a grassy, slightly savory note that keeps you coming back for more. I've had many matcha-flavored things, but this is the one that sets the standard. If you're new to Japanese Kit Kats, start here.

2. Sake — The Boozy Surprise

Sake-flavored Kit Kat? I was skeptical. But it's surprisingly subtle — the sake flavor is a gentle rice wine note that complements the white chocolate. It's not boozy or overwhelming; it's more like a sophisticated white chocolate truffle. This is a great one for adults who want something different. It's also beautiful — the packaging often features traditional Japanese patterns.

3. Hojicha (Roasted Green Tea) — The Smoky Delight

If matcha is the bright, grassy tea, hojicha is its smoky, toasty cousin. The chocolate has a deep, roasted flavor that's almost coffee-like. It's less sweet than matcha, with a complexity that makes it feel like a grown-up candy. I had this for the first time in Kyoto, and it's been my favorite ever since. Try it if you want something unique.

4. Sweet Potato — The Autumn Classic

Japan loves sweet potato, and the Kit Kat version is a perfect representation. It's sweet, creamy, and slightly nutty, with a flavor that reminds me of roasted sweet potatoes with butter. This is a seasonal flavor (usually fall), so grab it when you see it. It's comfort food in a candy wrapper.

5. Strawberry Cheesecake — The Indulgent One

This one is a dessert in a bar. The white chocolate base is mixed with strawberry bits and a cheesecake-like flavor. It's sweet, tangy, and surprisingly rich. I've given this to friends who aren't into Japanese flavors, and they've all loved it. It's a crowd-pleaser.

6. Wasabi — The Challenge

Yes, wasabi Kit Kat is real. And yes, it has a kick. But it's not as scary as it sounds. The wasabi flavor is mild — more like a hint of horseradish than a full-on sinus-clearing blast. The chocolate is white, and the wasabi is balanced with a touch of sweetness. It's weird, but it works. I recommend trying it as a novelty, but don't eat a whole bar in one sitting. Your nose will thank you.

7. Purple Sweet Potato — The Pretty One

Purple sweet potato is a popular ingredient in Japan, and the Kit Kat version is a visual stunner — the chocolate is a beautiful lavender color. The flavor is similar to regular sweet potato but slightly floral and less sweet. It's delicate and elegant. This is a seasonal flavor (usually spring), so it's a treat when you find it.

8. Yuzu — The Citrus Burst

Yuzu is a Japanese citrus fruit that's tart, aromatic, and slightly floral. The Kit Kat version is a white chocolate bar with a bright, refreshing yuzu flavor that cuts through the sweetness. It's like a lemon bar but more complex. This is one of my go-to flavors for summer — it's light and refreshing.

9. Black Sesame — The Nutty Surprise

Black sesame is a common ingredient in Japanese desserts, and it works beautifully in a Kit Kat. The chocolate has a nutty, slightly bitter flavor that's reminiscent of tahini but with a distinct sesame aroma. It's not sweet — it's savory-sweet, which makes it a great palette cleanser between other flavors. I love this one with a cup of green tea.

10. Soy Sauce — The One That Sounds Weird but Works

I saved the weirdest for last. Soy sauce Kit Kat sounds like a prank, but it's actually delicious. The flavor is salty and umami, with a slight caramel note from the soy sauce reduction. It's like salted caramel but with a deeper, more complex flavor. I was skeptical, but one bite converted me. It's a testament to how creative Japanese Kit Kat makers are.

Where to Find Them

You can find Japanese Kit Kats at Asian grocery stores, online retailers like Amazon or Japan Candy Store, or — best of all — in Japan itself. If you're traveling to Japan, the airport shops have massive selection boxes. I recommend buying a mix of flavors and sharing them with friends. They're conversation starters, taste adventures, and a delightful reminder that candy doesn't have to be boring. Go find your new favorite flavor. I'll be here, waiting for the next limited edition release.
