noun
durable article; long-lasting item
Refers to an item built to last for generations, such as furniture, tools, or household goods. Somewhat old-fashioned; in modern contexts, 耐久消費財 or 長持ちする品 may be more common.
祖母は箪笥を末代物として大切にしていた。
My grandmother treasured the chest of drawers as a durable article meant to last for generations.
Compound of 末代 (matsudai, 'for generations to come') + 物 (mono, 'thing'). The exact historical derivation is uncertain, but the word reflects a traditional appreciation for well-made, enduring possessions.
