Coco de Tea

Down a flight of stairs into a basement just steps from JR Otsuka Station, Otsuka Cafe Coco de Tea provides a welcome refuge from the bustling streets outside. Pushing open the basement door reveals a bright, tidy space where visitors can comfortably settle in for everything from a quick solo bite to an unhurried tea break.

Vibrant Mackerel Sandwiches and Hearty Lunch Staples

The headline dish that draws many diners is the "addictive mackerel sandwich" (yamitsuki saba sando). Thick-cut mackerel is brightened with lemon and layered with vegetables, making for a substantial yet refreshingly clean bite. The sandwich lineup also includes sweet-leaning options like the anko butter sandwich and anko cream cheese sandwich, alongside rotating weekly specials. For those looking for a heartier, rice-based lunch, the bone-in chicken Indian curry and the weekly rice plate are satisfying alternatives.

Mellow Onsen Black Tea and Fresh Baked Treats

Headlining the beverage menu is the signature Onsen Black Tea (Onsen Kocha®), crafted with tea leaves sourced from Kumamoto Prefecture. Available piping hot or as a clean, crisp cold brew, its gentle character pairs neatly with both savory plates and sweets. For teatime, the counter stocks several homemade scones, usually offering between 2 and 3 varieties, alongside fluffy s'mores pancakes and Basque cheesecake.

With complimentary Wi-Fi on hand, the cafe is well-equipped for spontaneous visits, whether for a weekday lunch or a weekend afternoon recharge. Between grab-and-go mackerel sandwiches and unhurried cups of hot spring black tea, this basement spot offers an easygoing retreat to match the mood of the day.
