Thunder Tech ITO EN Oi Ocha Japanese Green Tea 100 Tea Bags — Triangular Nylon, Zero Calories

Thunder Tech ITO EN Oi Ocha is a premium Japanese green tea sold as 100 triangular nylon tea bags that deliver authentic, zero-calorie brewed flavor from 100% domestic tea leaves.

From ITO EN — a Japan-based leader in tea since 1966 — this Oi Ocha green tea brings the taste of quality first-grade leaves into a convenient teabag format. Designed to express rich color, aroma and flavor, the triangular nylon filter allows water to circulate freely around the leaves so you get teapot-like infusion without the equipment. The product is direct-import and caffeinated, offering a classic roasted-green-tea profile with none of the calories.

What makes these tea bags taste closer to a teapot infusion?

The triangular nylon bag provides room for whole or lightly broken leaves to expand, which helps release oils, aroma and color more effectively than tightly packed pouch-style filters. The filter is intentionally coarse to let more flavor components pass into the cup while still trapping leaf fragments.

• Triangular shape permits fuller leaf expansion and better water flow.
• Coarse nylon mesh allows stronger aroma and richer color transfer.
• Made from first-grade domestic Japanese tea leaves for authentic taste.
• Single-serving sticks preserve freshness and are quick to brew.

How should I brew Thunder Tech ITO EN Oi Ocha for best results?

Use freshly boiled water slightly cooled (about 80–85°C / 176–185°F) for a balanced green-tea extraction; shorter steeping yields lighter flavor, longer steeping brings more robust notes. Steep one bag per cup for 30–90 seconds depending on desired strength, or multiple bags for a pitcher when serving several people.

• Ideal water temperature: ~80–85°C for balanced taste.
• Short steep (30–60s) for light, aromatic cup; 60–90s for fuller body.
• Use two to four bags per liter for iced tea or larger serving sizes.
• No sweeteners needed; naturally zero calories.

Is this product suitable for everyday use and convenience?

The product is packaged as 100 individually portioned tea sticks, making it convenient for home, office, or travel without sacrificing brew quality. Each stick keeps leaves sealed and easy to store, so you can prepare a consistent cup quickly, whether hot or iced.
