Description

Toh features straight, cylindrical cups connected in a single line to beautifully display the flow of water on rainy days. This simple vertical line blends quietly with your building’s appearance, acting as a modest accent on sunny days.

When it rains, water falls freely from cup to cup, creating a continuous, natural movement that draws the eye. Rather than using special effects, the design allows the rain to fall in its natural state, becoming a part of your home’s expression. It is simple, yet it makes the time spent listening to the rain feel calm.

By combining tubes of three different lengths, we create a gentle rhythm within the straight design, allowing it to fit naturally with modern walls and windows. The spacing between the tubes is designed to ensure the water flows in an unbroken, continuous line.

The Copper finish is unpainted, allowing the natural texture of the metal to shine. The color changes depending on the environment and weather, growing into a look unique to your home the longer you use it. This material is perfect for those who want to enjoy the passage of time as the copper develops a rich patina.

Based on traditional Japanese kusari-toi (rain chains), Toh rethinks how water is caught and released, resulting in a cleaner, simpler shape. It is a modern rain chain that manages rainwater while blending into the scenery as a piece of architectural art.

Rain Chains Crafted from Copper (C1100)

Copper is a timeless material for rain chain. At Seo Rain Chain, we use high-purity C1100 copper. This metal is 99.9 percent pure, which allows the surface to change naturally. It forms a protective layer called a patina. This layer shields the metal from damage and enhances its strength and beauty.

When we ship your chain, the copper has a reddish-brown glow. Over months and years, it deepens to a rich brown. Depending on where you live, it may eventually develop a soft green color. This transformation is not just aging—it is a sign that the metal is breathing in harmony with nature.

Copper is soft, so maintaining a perfect shape requires expert craftsmanship. We apply a hairline finish to the surface. This creates a calm texture and softens the light reflection.

As the rain chain changes with the seasons, it brings a quiet character to your building. Outside of Japan, similar items are often sold as "Bronze Rain Chains," but most are actually made of copper. Our pure C1100 copper naturally develops that rich bronze tone over time, highlighting the material’s lasting elegance.

Copper

This is raw, uncoated copper. Over time, the color deepens and can develop a patina—a natural surface that forms as copper ages outdoors. The change feels calm and organic, which many people love in a copper rain chain.

Support

Can I install the rain chain myself?

Working at heights on a roof can be dangerous, so we recommend hiring a professional roofer. However, some models are easier to install if you feel comfortable doing so yourself.

Please review our How To Install page to decide. If you are replacing a pipe downspout, you will need to remove or cut the pipe, so we recommend a professional for that task.

When will my order arrive?

If your item is in stock, we typically assemble and ship it within one week. (Hamon models may take up to three weeks). Once shipped, we will send you a tracking number so you can see exactly when it will arrive.
Note: If an item is out of stock, we handcraft it to order, which takes 3 to 4 months. Please order early if you have a specific deadline.

Can I adjust the length of the chain?

Yes, we can make the chain to your desired length. Lengthening it yourself is difficult and may cause it to detach, so we suggest ordering a slightly longer chain and cutting it on-site.

If you are unsure about the length (especially when converting from feet), please contact us for advice.

Connecting Method for Extending Toh, Ta-ke, and Tama.

Please note that the price changes based on length.
