A masu (升) is a square wooden cup, jointed at the corners without a single nail, that Japan used for centuries to measure out rice and sake before the metric system arrived. The one covered here is a 180 ml ichi-go (一合) measure in unfinished hinoki (檜, Japanese cypress), made in Ogaki — a former castle town in western Gifu that quietly produces an estimated 80 percent of all the wooden masu in Japan. The listing references a piece from Ohashi Ryoki, sold under the Masuza Ogaki name.
What makes the masu interesting to an international reader is not novelty but continuity. The same spring-fed canals that earned Ogaki the nickname Suito (“City of Water”) once powered its mills, and the woodworking trades that grew up around that water still joint cypress the way the Edo-period merchants did. Pour cold sake into a raw hinoki masu and the wood’s citrus-resin aroma transfers straight into the drink — that is the entire point of the object, and it is the one thing a photo cannot convey.
This guide is for readers deciding whether a hinoki masu belongs in their cupboard, and how to get one shipped outside Japan. We cover what the piece is, how to choose a size, where to buy it (Amazon US search first, Amazon JP Global Store for the sourced listing, plus proxy options), what it does well, and the honest caveats of owning unfinished wood that touches alcohol.

📖 Glossary — key terms in this guide
- masu (升) — a square wooden box used historically to measure rice and sake; now used as a drinking cup and ceremonial vessel.
- ichi-go (一合) — one gō, the traditional unit equal to 180 ml. A 1-go masu is the everyday drinking size.
- hinoki (檜 / ヒノキ) — Japanese cypress, a pale, fragrant softwood prized for its citrus-resin aroma and used in baths, shrines, and woodware.
- kagami-biraki (鏡開き) — the ceremonial breaking of a sake-barrel lid at New Year, weddings, and openings, where sake is served in masu.
- engimono (縁起物) — a lucky or auspicious object. “Masu” (升) is a homophone for masu (“to increase / prosper”), which is why it appears at celebrations.
- Suito (水都) — “City of Water,” Ogaki’s nickname, from the spring-fed canals that once powered its merchant district.

Where this comes from — place, era, and the craft
Ogaki sits on the Mino plain in western Gifu, where groundwater rises so freely that the old merchant quarter was laced with spring-fed canals. That water is the reason the town exists in the form it does. It powered mills, it floated timber, and it gave Ogaki the nickname Suito — the City of Water — long before it became a woodworking hub.
Through the Edo period (1603–1868), Ogaki was a castle town and a node on the routes crossing the Nōbi basin. Clean water and steady timber supply pulled woodworking and milling trades into the district, and among them was the making of masu: the square measures that portioned rice and sake in an economy that ran on volume, not weight.
Today that legacy has concentrated rather than dispersed. Ogaki produces an estimated 80 percent of all the wooden masu made in Japan — a striking degree of regional specialization for an object most Japanese households still keep at least one of.
- Edo period begins (1603) — Castle towns and merchant trades flourish; Ogaki grows around its spring-fed canals.
- Edo period — The masu standardizes how rice and sake are portioned in commerce; the ichi-go (180 ml) becomes a familiar unit.
- 1868 — The Meiji Restoration opens Japan to modern industry; Ogaki’s woodworkers keep jointing cypress by hand.
- Early–mid 20th century — As Japan adopts the metric system, the masu loses its role as an official measure and survives as a drinking and ceremonial vessel.
- Present day (2026) — Ogaki produces an estimated 80% of Japan’s wooden masu; makers such as Masuza and Ohashi Ryoki joint the corners with no nails, using knot-free hinoki.
“Pour cold sake into a raw hinoki masu and the cup stops being a container — the wood’s citrus-resin scent becomes part of the drink. That is the whole point of the object.”
The masu also carries quiet ritual weight. Its character, 升, is a homophone for masu (“to increase” or “to prosper”), which makes it an engimono — a lucky object brought out for New Year kagami-biraki, weddings, and shop openings. That is also why it pairs naturally with Gifu’s other Edo-rooted trades: Mino washi paper and the blades of nearby Seki. A masu, a sheet of washi, and a Seki knife are three faces of the same regional woodworking-and-water economy.

What it does well
Weaknesses and things to verify before buying
- Not dishwasher-safe. Unfinished wood should be hand-rinsed and air-dried; the dishwasher will warp, crack, or grey it.
- The aroma fades. The hinoki scent is strongest when new and diminishes with use and washing. This is a consumable pleasure, not a permanent feature.
- Flavor is not for everyone. If you dislike woody or resinous notes, the very thing the masu does best will work against you.
- Raw wood and liquid need care. Prolonged soaking, staining drinks, or storing it damp can lead to mold, odor, or splitting. Rinse, wipe, and let it dry fully.
- Specs and price are unconfirmed here. Exact dimensions, weight, and current price were not in our source data — verify all three on the live listing.
- Not leak-proof for hot liquids. It is built for cold or room-temperature sake, not as a sealed cup for hot drinks.
