ものしらべ: 日用品を「1回あたり」で比べる

Why it surfaced

ものしらべ compares 111 products across categories including emergency supplies, food, pest control, cleaning, hygiene, and pet care. Its premise is pleasingly concrete: a ¥1,283 box of drip coffee can cost ¥64 per cup, while a ¥3,336 box costs ¥33—and the site also reads the low-rated reviews before making its picks.

A Japanese comparison site that recalculates everyday products by the unit that actually matters: per meal, cup, use, litre, or 100 grams.
