Japan's caffeine-free roasted barley tea — the taste of Japanese summer
Mugicha (麦茶) — roasted barley tea — is arguably Japan's most beloved everyday beverage, surpassing even green tea in summer consumption. Unlike sencha or matcha, mugicha is completely caffeine-free, made by steeping dark-roasted barley grains in water to produce a deep amber, toasty, slightly nutty drink. Every Japanese household keeps a pitcher in the refrigerator from June through September, and children grow up drinking it instead of juice or soda.
Barley has been cultivated in Japan since the Yayoi period (300 BCE–300 CE), and roasted barley grain infusions appear in records from the Heian period (794–1185). By the Edo period (1603–1868), mugicha vendors sold chilled barley tea from street stalls (mizuya chaya) during Tokyo's brutal summers, making it one of Japan's earliest commercially sold cold beverages. The modern tea bag format was introduced in the 1980s and transformed mugicha into a daily household staple.
Sencha (Green Tea)

Hojicha (Roasted Tea)
Low caffeine, smoky, from roasted green tea leaves
Stay in Tokyo to experience Japan's full beverage culture — from morning green tea at a traditional teahouse to ice-cold mugicha at a local izakaya. Tokyo's depachika (department store basement food halls) stock artisan mugicha brands not found elsewhere.
Mugicha (麦茶) is roasted barley tea — a caffeine-free beverage made by steeping or cold-brewing roasted barley grains in water. It has a distinctive toasty, slightly bitter, nutty flavor with a deep amber color. In Japan, mugicha is the quintessential summer drink, served ice-cold in pitchers at every household, restaurant, and izakaya from June through September. Unlike green tea or black tea, mugicha contains no caffeine or tannins, making it suitable for children and people sensitive to caffeine.
The easiest method: place 1–2 mugicha tea bags (roasted barley bags sold at every Japanese supermarket) in a 1-liter pitcher of cold water and refrigerate for 6–8 hours (cold brew). Alternatively, boil 1 liter of water, add 1 tea bag, steep for 10 minutes, then cool and refrigerate. The cold-brew method produces a smoother, less bitter flavor. Japanese families make a fresh pitcher every 1–2 days throughout summer. Loose roasted barley grains can also be dry-toasted and brewed for a more artisanal result.
Japanese mugicha, Korean boricha (보리차), and Chinese dàmàichá (大麦茶) are all roasted barley tea and are essentially the same beverage with regional variations in roasting intensity and brewing convention. The Korean and Japanese versions are the most similar. Western "barley water" is different — it typically involves boiling pearl barley with lemon and sugar to make a sweet, thick drink. Japanese mugicha is unsweetened and tea-like.
Mugicha is rich in antioxidants, particularly p-coumaric acid and pyrazines, which may help improve blood circulation and reduce blood viscosity — particularly valuable in hot Japanese summers. It contains no caffeine, making it a safe evening drink and suitable for children. Traditional Japanese wisdom holds that mugicha cools the body in summer heat. It also contains melatonin precursors and minerals including potassium. Modern studies suggest its antioxidant content rivals some green teas on certain metrics.
Mugicha is available everywhere in Japan: every convenience store (7-Eleven, Lawson, FamilyMart) stocks cold mugicha bottles year-round; supermarkets sell tea bag packs (Kataoka Bussan, Itoen, Suntory brands); vending machines have bottled mugicha; and pharmacies stock the bags. The iconic Kataoka "Hitoshi-kun" brand in the red box is the most recognized supermarket mugicha. As a souvenir, a box of premium mugicha tea bags makes a lightweight, unique gift.
