Hario ChaCha Kyusu Maru 450 mL Glass Teapot: Room for Loose Leaves

Loose leaves packed into a tiny infuser have little room to open. The Hario ChaCha Kyusu Maru 450 mL glass teapot gives them a broad, removable basket inside a transparent brewing vessel. Its appeal is straightforward: space for loose-leaf tea, a clear view of the infusion, and a pot you can pour from when the tea is ready.

This is the clear CHJMN-45T, with a glass lid and stainless steel strainer. It is a compact everyday teapot for brewing with water heated separately.

Give loose leaves room to open

Hario describes the metal strainer as spacious enough for leaves to expand. That is a useful reason to consider this pot if your usual infuser feels crowded once the leaves unfurl. The basket sits inside the rounded glass body, holding the loose leaves in a removable insert while they steep in the water.

The strainer lifts out as one piece. Once your chosen steeping time is up, you can remove the leaf-filled basket and keep using the pot for pouring. Have a saucer or another suitable resting place ready for the wet strainer; it becomes a separate item on the table.

That arrangement suits someone who wants to lift out the basket after steeping, then pour a batch in stages. Basket space still leaves the tea recipe to you: leaf quantity, water temperature and steeping time should suit the particular tea.

See the infusion, then pour from the same pot

The pot and lid use transparent borosilicate glass. You can watch the tea's color develop and see how much liquid remains before pouring another small cup. For drinkers who enjoy the appearance of green, black or herbal tea, the clear body makes that part of an ordinary brewing session.

Color alone does not measure temperature or establish the right steeping time. The glass provides a view of the tea; your chosen brewing method still controls those decisions.

Hario's instructions say to support the lid when pouring. The glass handle provides the grip, but the lid should not be treated as a locking closure. This is tableware for careful handling, especially when moving hot tea between a counter and the table.

Keep cleanup accessible

Removing the lid and basket exposes a wide opening. Hario lists a 94 mm mouth diameter for this 450 mL model, and the manual shows a sponge reaching into the glass body. That access matters if narrow-necked pots make it awkward to reach the inside during hand washing.

The separate basket lets you empty the used leaves before cleaning the glass. Hario permits dishwasher use; for hand washing, the manual specifies a soft sponge and neutral detergent, without abrasive cleaners or metal scrubbers. When cleaning the basket, check for leaves caught against the mesh before putting it away.

Easy access does not make the glass unbreakable. Handle the pot and lid gently, and stop using a part with cracks, chips or deep scratches, as the instructions require.

Choose a small pot and heat water separately

The CHJMN-45T has a practical capacity of 450 mL, about 15.2 US fluid ounces. Hario separately lists 520 mL filled to the brim; use the practical figure when deciding whether the pot suits your serving routine.

Heat water separately, then use the pot for steeping. Hario allows microwave reheating after the metal strainer is removed. Do not heat the pot empty or with only a little liquid. Stovetop heating and oven use are prohibited.

Choose this size when a modest batch and a separate pouring vessel suit the way you drink loose-leaf tea. If you brew directly in one mug and already like your infuser, another pot may add washing without adding much convenience.
