Ketogenic Coffee Japan

As part of what will be a series of blogs about ketogenic dieting in Japan, today I am sharing where you can source your ketogenic coffee supplies in Japan – how to make it!

For the uninitiated, Ketogenic coffee is a high fat, high calorie zero carb breakfast brew which is often referred to as ‘bullet proof coffee‘. I intermittent fast daily and drink this as a replacement for a breakfast meal. The calorie density is more than enough to take me through until mid afternoon without feeling hungry at all.

So, let’s get started with Ketogenic coffee in Japan!


  1. Butter (1tbs)
    I use trappist butter which is a fermented product made by Trappist monks in Hokkaido, seriously delicious butter and can be purchased in most major supermarkets or you can buy online on Rakuten. This butter does contain salt and a lot of recipes call for ‘no salt’ but I don’t mind the slightly salty flavour of the coffee and happy with the extra benefit of having a fermented product in my diet.
  2. Coconut Oil (1tbs)
    I use Brown Sugar 1st Organic Extra virgin coconut oil (despite the name, there is no sugar in it!) Also available in most major supermarkets or Rakuten. If you can’t find this brand generally there will be an organic extra virgin brand available.
  3. Coffee (1-2 scoops according to taste)
    One thing Japanese do love is a coffee brew and generally there is no shortage of roasters and I recommend a hunt around your local area to source some organic origins coffee beans.





  1. Coffee Brewer – I use the aeropress purchased from Tokyu Hands store.
  2. Blender – I love my blender and own a vitamix, which I also purchased from Tokyu Hands, of course any decent blender can do the job here and you don’t need a heavy duty, just enough to mix the butter and coconut into the coffee.
  3. Kettle / Water Boiler – No explanation really needed here!



  1. Boil water
  2. Brew the coffee
  3. Place butter, coconut oil and coffee in blender
  4. Blend until creamy
  5. Serve and enjoy!

About The Fit Japan Guy

After moving to Japan I found there is so much more to the health and fitness scene than I could ever have realised, but sadly much of it is not apparent to foreigners. It is my goal to help people discover the health and fitness lifestyle opportunities that Japan has to offer.
