A Whimsical Escape & Coffee Obsession – My Visit to Mermaid Coffee Roasters, Ikebukuro, Tokyo

#tokyospots

Nestled just a short stroll northeast of Ikebukuro Station (Toshima-ku), Mermaid Coffee Roasters is a memorable blend of specialty coffee, eclectic decor, and warm hospitality. Housed in a four-story building that’s part café and part vintage collector’s refuge, it opened in 2022 and quickly became a favorite for locals and visitors alike .

I arrived at about 10 AM on a weekday and spent around 1.5 hours savoring both drinks and ambience across the basement to rooftop levels. Each floor has its own character—eclectic art, antique furniture, plants, and hidden mermaid motifs woven through the decor.

Highlights:
• ☕ Coffee selection & tastings: Home-roasted beans from dark to medium roast are displayed near the entrance—and you can sample them before ordering. I opted for a fruity medium roast oat-milk latte and later, an ice latte that balanced crispness and sweetness perfectly ().
• 🍪 Snacks & pastries: The matcha scone (delicate, subtly sweet) and green-tea cookies paired well with the coffee. The rotating snack menu includes spinach-cheese danish, roasted tea scones, and gelato with banana and coffee flavors .
• 🏛️ Atmosphere: The décor is whimsically medieval-meets-mermaid—framed art, seashell motifs, carved wood, mismatched chairs—yet feels cozy and almost homely in its eccentricity .
• 🪑 Seating & vibe: Seating is generous across four floors, with power outlets and Wi-Fi on most levels—many visitors come to work or relax. Staff offer friendly guidance and sometimes even walk you to the door on departure—a level of hospitality consistently praised in reviews .
