Best Japanese Green Tea: A British Tea Lover’s Complete Guide

When you think of tea, you probably picture a warm cup of English Breakfast. But there’s a whole world of green tea out there—especially from Japan—that deserves a spot in your kitchen cupboard.

In this guide, we’ll take you through the best Japanese green teas, how they’re different, why they’re so good for you, and where you can buy authentic ones without getting lost in confusing jargon.

Let’s dive in.

What Makes Japanese Green Tea Special?

Japan’s relationship with green tea goes back over 800 years. But what makes it stand out from other teas?

Simple: steaming and freshness.

Unlike Chinese green teas, which are often pan-fried, Japanese green teas are steamed after harvesting. This process locks in their vibrant green color and gives them that signature fresh, grassy taste with a subtle umami kick.

You might hear terms like:

• Sencha: the everyday hero of Japanese green tea.
  
• Gyokuro: a luxury tea, shade-grown for extra sweetness.
  
• Bancha: a gentle, milder tea for casual sipping.
  

Each one has its own charm. More on that next.
