On the 2nd floor of Machida Marui, the "Probably... The World's Smallest Chocolate Factory" (たぶん…世界一小さいチョコレート工場) Machida Marui store is opening as the brand's first store in Tokyo. The lineup ranges from handmade chocolate made with marshmallows and dried fruit to okaki rice crackers from the same group company, offering a mix of sweet and salty treats to enjoy.
An SNS Sensation Makes Its Tokyo Debut
"Probably... The World's Smallest Chocolate Factory" has built a devoted following in Togane City, Chiba Prefecture, and is now opening its first store in Tokyo. It's the kind of shop that makes you want to peek inside and see what kind of chocolate awaits, and now that experience is available in Tokyo, too.
The shelves are lined with handmade chocolate made with marshmallows and dried fruit, as playful to look at as it is to eat. The shop also carries okaki rice crackers and other snacks from its sister company, rounding out a lineup that goes beyond chocolate alone.
Finish a piece of chocolate, and a salty okaki starts to sound good. Finish the okaki, and the pull of something sweet returns. Before long, it's easy to find a hand reaching for "just one more" — the interplay between sweet and salty is part of the fun. Even deciding which one to try next brings its own kind of excitement.
With its approachable, familiar treats, the shop makes for a small treat for yourself or a gift for family and friends. Stop by to find something you'll want to tell others about.
Product Lineup (Selected Items)
Marshmallow Choco (120g)
Price: ¥480 (tax included)
A shop favorite. Crisp crackers layered with soft, fluffy marshmallow and coated in chocolate deliver an addictive contrast of crunchy and fluffy textures. The crackers' light saltiness sets off the sweetness of the chocolate and marshmallow, making it easy to reach for "just one more" with every bite.
Really Delicious Chocolate (めちゃうまチョコレート) (170g)
Price: ¥550 (tax included)
Simple is best. A classic milk chocolate that lets the rich flavor of cacao shine. One bite brings a mellow sweetness and cacao aroma without any extra additions, letting the chocolate's own flavor take center stage. Its smooth, melting texture keeps you reaching for just one more bite.
Hokkaido Milk Choco (34g)
Price: ¥120 (tax included)
A rich milk flavor made with 100% Hokkaido milk, in a size perfect for finishing in one go. One bite fills the mouth with creamy milk richness and gentle sweetness, and the easy-to-finish size makes it a welcome snack whenever you want something a little sweet.
Kaki no Tane Pot (柿の種ポット) (400g)
Price: ¥730 (tax included)
Made using a traditional method that's still followed today, this crisp, savory kaki no tane lets the ingredients' flavor come through. The mild spice level makes it easy for kids to enjoy too, and it's the kind of snack that keeps you reaching for another handful — great for yourself or as a small gift.
Lucky Mayonnaise (34g)
Price: ¥105 (tax included)
A mellow mayonnaise-flavored okaki with a popular, eye-catching package. One bite brings the rich flavor of mayonnaise, an addictive treat worth trying whether you're a mayonnaise lover or someone who wouldn't normally reach for a mayo-flavored snack. It might even bring a bit of luck when you eat it.
