Discover the Flavors of Iwate: April’s Onsen Box Sweets Selection

Spring is a time of renewal, and what better way to welcome the season than with a selection of exquisite sweets from Iwate Prefecture? Nestled in the northeastern Tohoku region of Japan, Iwate is known for its breathtaking natural beauty, historic hot springs, and deep-rooted culinary traditions. This month, Onsen Box brings you a taste of Iwate with four delightful confections, each with a story as rich as its flavor.

Iwate Prefecture & Its Hot Springs

Iwate is home to some of Japan’s most serene onsen (hot springs), including Hanamaki Onsen, a picturesque retreat surrounded by lush forests, and Tsunagi Onsen, known for its healing waters overlooking a peaceful lake. After a rejuvenating soak, many visitors indulge in local sweets that perfectly complement the onsen experience.

Let’s take a closer look at the specialty treats featured in this month’s Onsen Box!


1. Sakura Cake – A Seasonal Delight

Spring in Japan is synonymous with cherry blossoms, and this beautifully crafted Sakura Cake captures the essence of the season. Made by Takachiyo, a confectionery shop with over 100 years of history, this delicate cake is shaped like a cherry blossom and embodies a perfect blend of Japanese and Western pastry traditions. Using high-quality, house-made ingredients, Takachiyo ensures that every bite is as elegant as the season itself.

Why you’ll love it: A soft, aromatic cake that pairs wonderfully with tea, making for a perfect afternoon treat.


2. Busu no Kobu – A Name with a Story

At first glance, the name “Busu no Kobu” may sound unusual—it translates roughly to “ugly bump.” However, its origins trace back to the indigenous Ainu people of northern Japan. The term refers to a geographic feature rather than appearance, making it a fascinating piece of cultural history.

Created by Sawagiku, a confectionery shop established in 1930, this treat features a crisp outer layer baked with butter and a rich filling of slow-cooked sweet red bean paste. The combination of textures and flavors makes it a delightful snack, especially when paired with green tea or coffee.

How to enjoy it: Lightly warm it in an oven or toaster to enhance its crispiness and bring out the buttery aroma.


3. Choco Nanbu – A Unique Crunchy Treat

Tohoku’s beloved Nanbu Senbei (traditional rice crackers) take on a whole new form in this innovative confection. Choco Nanbu crushes freshly baked rice crackers and coats them in premium chocolate, creating a one-of-a-kind crunchy chocolate snack. The balance of roasted peanut flavor and smooth chocolate makes for a satisfying bite.

Iwate’s well-known confectionery brand, Iwateya, a subsidiary of Komatsu Seika, produces this sweet. With meticulous attention to ingredients and technique, they’ve turned a traditional savory snack into an irresistible chocolate delight.

Perfect for: Those who enjoy the contrast of crispy and creamy textures in their sweets.


4. Kurumi no Mori – A Nutty Indulgence

Crunchy yet delicate, Kurumi no Mori is a refined treat featuring layers of buttery cookies sandwiched with hazelnuts, walnuts, and a hint of orange essence. The nutty richness is beautifully complemented by a subtle citrus aroma, making it an ideal companion for a cup of coffee or tea.

Why you’ll love it: A well-balanced combination of nuts and citrus that melts in your mouth with every bite.
