I love saba sandwiches so much that I try them everywhere—at restaurants, at markets, even while traveling.
And you know what? This version is the one. As long as your ingredients are fresh, it’s unbelievably good.
Honestly, not making it feels like a loss—it’s that delicious.
Perfect for breakfast, lunchboxes, or even parties!

"I’m a fun-loving chef and devoted foodie, so captivated by Hokkaido’s incredible variety of ingredients that I decided to make it my permanent home. I’ve been living here for 20 years. In spring, I forage for wild vegetables; in summer, I camp; in autumn, I hunt for mushrooms; and in winter, I ski. I’m an active explorer who chases seasonal flavors and gourmet experiences all across Hokkaido—even if it means spontaneous long-distance trips. My motto is: “If the night is fun, tomorrow will surely be even better!” I focus on creating recipes for flavorful appetizers that liven up the evening and hearty main dishes that make you want to keep reaching for more rice."
