Natsume vs tea caddy
A working container against a storage one, and confusing them costs the tea. A natsume holds the sieved powder for a single occasion; a caddy is built against the four things that degrade tea — air, light, heat and moisture — over months.

What is being compared
Point by point
| Aspect | Natsume (matcha caddy) | Tea caddy |
|---|---|---|
| Time horizon | One occasion. | Months. |
| Airtightness | Not the design priority; it is a working container. | The design priority. Japanese double-lidded chazutsu are the most airtight traditional form. |
| Light | Opaque, classically lacquered wood. | Opaque; a clear jar on a sunny shelf is the standard mistake. |
| What goes in it | Sieved matcha, prepared in advance. | Any leaf tea, and matcha in its unopened tin. |
| Cultural weight | Significant within chanoyu, where the choice of caddy carries seasonal and formal meaning. | Practical; a caddy is a container. |
| What happens if you use the wrong one | Matcha stored in a natsume for weeks loses colour and aroma quickly. | Nothing, except that it is a less appropriate object for the occasion. |
The short answer
Matcha is the most fragile tea in the catalogue and the object it is presented from is not the object it should be kept in. The practical rule is to keep the tin sealed and cold and to fill the working container only for the session in front of you.
