We are one of just eight restaurants in the UK to serve certified Kobe beef.

To qualify as Kobe beef, it must come from Tajima Japanese Black cattle raised in Hyogo, Japan – which is usually only around 3,000 cattle each year, most of which remain in Japan. There is also an extensive range of additional criteria that all cuts must meet to be certified as Kobe. For e.g. they must be fed a specific diet consisting of dried grasses and special mixes of soybean, corn and barley, slaughtered between the age of 3 and 5 years, produce beef that has high marbling that meets tough grading criteria, meat quality score of 4 & 5 only.


Wasabia Japonica, more commonly known simply as wasabi, originated in Japan and has been widely used in authentic Japanese cookery since the 10th century. Unlike the often intense and overpowering pastes and condiments, fresh wasabi is subtle and aromatic, with a gentle note of spice and a predominantly herbal flavour. Notoriously challenging to cultivate, the wasabi plant thrives in Japan’s mountain regions, and our wasabi is sourced directly from there. We serve our wasabi fresh at the table using a sharkskin grater to ensure maximum flavour.


Widely considered the best sushi rice in the world, Japanese Koshihikari was cultivated in 1956 from two different strains of short-grain rice to create a hybrid that retains moisture for longer, making it perfect for sushi-shaping. With a distinctive texture and taste, Koshihikari is renowned for its consistency, aroma and natural sweetness.


We offer a range of different aged soy sauces, and the soy we select depends entirely on the fish it’s being served with. We believe that each fish needs a different level of flavour and salinity to bring out its natural umami to the fullest. Our range is extensive, with two, three, five, ten, twenty and thirty-year-old varieties used daily at our pass.

All our soy sauces are brewed in 100-year-old cedar barrels and sourced from the Okada family, who has been making soy sauce since 1753. They brew according to traditional methods passed down by generations and are the only brewers in Japan to use the old mushiro (woven mat) method of making the koji base, which forms the foundation of soy sauce.
