Description

Migumo L is a rain chain with a classical presence, designed on a scale suitable for large roofs and wide outdoor spaces.

We apply a blackish coloring to the copper surface and polish it to leave parts of the raw copper visible, creating a deep, textured expression. The design is built to handle higher drainage volumes, catching water and guiding it downward even during heavy rain.

When it rains, the sight of water falling in a continuous line overlaps with the shape of the chain, bringing the movement of water into the exterior design. The structure, combining copper petals with stainless steel links, balances artistic design with durability. Even on large buildings, this form blends naturally as part of the architecture.

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.

Patinated Copper Finish

This finish is only for the Mizumo model. We darken the copper with a sulfide patina, a treatment that creates deep tones, then polish parts of the surface to reveal a soft pattern. A clear topcoat protects the finish while keeping its layered look.

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.

To learn more about extending chains, see:
Connecting Method for Extending Toh, Ta-ke, and Tama.

Please note that the price changes based on length.
