ROKUMEI COFFEE CO. (ロクメイコーヒー グランスタ丸の内店) brings the craft of an award-winning Nara roastery to the heart of Tokyo Station. Founded by a Japan Roasting Champion, this small but serious coffee stand focuses on meticulously prepared single-origin pour-overs, with a choice of roast levels for each bean. They also offer a Tokyo-exclusive blend, alongside a full range of espresso drinks and high-quality retail beans.
Guests consistently praise the quality of the coffee, from the nuanced pour-overs and cold brew to the well-made flat whites and lattes. The knowledgeable staff are often highlighted for their ability to guide customers through the bean selection. Pastries, especially the classic and ham-and-cheese croissants, are popular, as is the unusual pairing of coffee with a coffee-flavoured yokan (a traditional sweet jelly). Many visitors leave with bags of beans or drip-bag coffee as souvenirs.
The shop's main drawback is its size. With limited seating, it gets crowded quickly. A few reviewers noted that service can feel brusque during busy periods, and some were asked to purchase a drink to occupy a seat or to leave after finishing their food. However, for most, the quality of the coffee makes it a worthwhile stop.
Reviewers in 2024–2026 paid around ¥580 for the 'today's coffee', ¥650 for a single-origin pour-over, ¥700 for a cold brew, and ¥780 for an oat-milk latte. A croissant was about ¥330, and a morning set cost around ¥920. The typical spend is between ¥1,000 and ¥1,999, which most visitors consider good value for the high quality in such a central location.
