Journal
Articles written from the data on this site. Nothing here is a rewrite of what you can read anywhere else.
Rules these articles follow
- Facts carry a source URL and the date they were checked. Opinions are labelled “Our reading”.
- No rankings. No “top 10” lists — things are grouped by whether they apply, or by third-party awards.
- Numbers in tables are never written into the article. They are rebuilt from the published data every time the site is built.

How competition awards have changed over the years
A year-by-year view of awards can show how wine competitions around Japanese wine have expanded. What is counted here is the set of records that could be imported from official results as Japanese-wine awards. Read the boundary of the dataset before interpreting any rise or fall.

Where shops carrying Japanese wine appear on the web
When looking for a shop that carries Japanese wine, appearing in search results is not the whole question. Separating a shop’s own site, directory or profile pages, and online store presence helps explain how it appears on the web. As elsewhere in this database, being difficult to find is not the same as not existing.

Producers found nationwide, and producers found close to home
Following listed shops shows where a producer’s wine may be found. This table is not a count of stock across Japan. It collects only relationships published by producers and supported by a verifiable source. Use it as a starting point for a search, while keeping the meaning and limits of the figures separate.

Producers whose names appear often in competitions
Grouping competition awards by producer shows whose names have appeared in published results over time. This is not a score assigned by the editorial team. It is an accumulation of third-party results within the range that could be verified. Read it together with entry practices and the records that remain available.

What is being grown in each prefecture
The variety distribution shows that the grapes producers identify publicly differ by prefecture. The count covers varieties that producers have said they grow; it does not show the source of purchased grapes or vineyards that have not been disclosed. Read the distribution by separating what is recorded from what remains a hypothesis.

How many wineries are there in Japan? — Checked against a public register
When counting Japanese-wine producers, a list of listed entries cannot by itself prove that it is complete. We compared the database with the National Tax Agency’s public register of licensed alcohol-production sites and separated records matched to listed producers, records outside the scope, and records whose current status remains unconfirmed. The table is a boundary that can be checked from outside, not a contest in counting.

How quickly new names enter wine competitions
Whether the number of awards has grown and whether new producers have appeared in competitions are related but different questions. Here we followed the imported competition records by producer and counted the year in which each producer first received an award. The table shows an entry point into the spread of recognition for Japanese wine, within the records we could import.
Data ／ 2026-08-27
Why newer producers have fewer recorded awards
When founding years are set beside award records, newer producers can appear to have fewer awards. The question here is not how many awards each producer has, but the share of producers in each founding period with any recorded award. Using the share of each group helps keep opportunities to enter a competition separate from judgments about quality.

What “Gold” Means Depends on the Competition
Gold, Gold Medal, and Double Gold signal high evaluation, but they are not identical measures of rarity. This table helps readers interpret the composition of imported award records by competition.

Where Producers Appear on the Web
Looking only for an official website can make producers easy to miss. Information is spread across websites, shops, Instagram, and X. This table reads communication and sales through the kinds of URLs we could confirm.

Where This Site Is Thin
Showing where information is well covered also reveals where it remains thin. This table is not a contest for listing counts; it reviews, by prefecture, how far addresses, visit information, and varieties have been confirmed.
Data ／ 2026-08-27
How fast are new Japanese wine producers appearing?
Counting when wineries appeared usually means using the founding year each producer publishes. But a founding year means different things to different people: a sake brewery will give the year it started making sake, and producers who publish nothing cannot be counted at all. This article uses a different figure — the date the National Tax Agency recorded a fruit-wine production licence.
Data ／ 2026-08-27
Where new producers are appearing
Ranked by the number of producers listed, Yamanashi, Nagano and Hokkaido come out on top. But that count treats a producer founded a century ago and one licensed last year as the same single entry. Counting only the fruit-wine licences newly granted over the past decade or so, by prefecture, shows that those same three look quite different from one another.
Data ／ 2026-08-27
Where Are the Awards Concentrated?
When producers with awards are lined up, their award counts are far from evenly distributed. That pattern is not a direct ranking of quality. The table should be read as a distribution shaped by continued entry and by the way records accumulate.
Data ／ 2026-08-27
Have the Varieties Producers Plant Changed Over Time?
When planted varieties are grouped by the period in which producers were founded, different names appear among older and newer groups. This is not a measure of planted area across the market; it is a reading of the producer records that could be confirmed.

How Many Fruit-Wine Production Sites Does the Government Count?
When we check the number of producers, the government’s statistics and this site’s listings are not measuring the same thing. Using the National Tax Agency’s licensed-site counts, this article clarifies what is counted and what remains unknown.

The Same Wine Can Be Entered Under Different Names
If competition results are counted exactly as published, awards for the same wine can appear to belong to separate wines. This article considers how far to consolidate variations in entry names, and where to stop.

How many gold awards are there? — The distribution of award tiers
We place the award tiers from three competitions side by side while preserving the names published by each organiser. The table shows why the same-looking word “gold” does not have the same system or entry pool across competitions.

When were Japan’s wineries established?
We look across Japanese wineries by the decades in which their founding years can be verified. The table shows the growth of newer producers alongside long-running ones, while remaining a lower bound because many founding years are not yet confirmed.
Data ／ 2026-08-27
Where can you find shops that carry Japanese wine?
We map shops by prefecture using only retailer and restaurant relationships with producers that can be verified with sources. Separating places to buy from places to drink shows a distribution that is different from the map of wineries themselves.
Data ／ 2026-08-27
Wines that keep winning over the years
We group wines whose award records continue across multiple years for the same producer and product name. After normalising variations in how names are written, the table traces a record of sustained recognition distinct from a single-year award.

The grape varieties grown by the most producers in Japan
We count the grape varieties that Japanese producers publicly say they grow. This is a view of cultivation, not awards, and it covers only producers whose varieties could be verified, so the table is a lower bound.

Where Japan’s wineries are found
The prefectural distribution is a useful first guide when looking for Japanese wine. The table, however, shows the producers verified in this database, not every winery in each prefecture. Read it alongside the status of addresses, visits, varieties, and region labels rather than treating the size of a column as the whole story.

Winery visits: where to book and where you may walk in
This guide groups winery visits by prefecture into three states: no reservation required, reservation required, and not checked. It shows the range of visit information we could verify, without treating missing information as a refusal of visitors.
Practical guide ／ 2026-08-27
Wineries you can reach without a car
We identify wineries that can be reached on foot from a station using the access information published by each producer. Walks from bus stops are excluded, and the result is a lower bound because it covers only producers with verifiable access notes.

Wineries where you can stay and eat
Explore wineries by what you can do there: stay overnight, eat at a restaurant, or stop at a café. We separate confirmed cases from information not yet checked and set out what to verify when planning a visit.

Wineries with free tastings and wineries with paid tastings
Tasting is one of the pleasures of visiting a winery. Choosing a destination only by whether the tasting is free or paid can hide the need for a reservation, what can actually be tasted, and the conditions for purchase. The table below separates confirmed tasting states and leaves unverified cases unverified.

Buying without visiting — choosing between shops and online stores
Visiting a distant producer is not the only way to buy its wine. Listed shops and the producer’s official online store can make it possible to search without traveling. The strength of a source and the certainty of current stock are different things. Check who published the relationship, then confirm the final details with the shop or producer.

Koshu and Muscat Bailey A — two varieties native to Japan
Koshu and Muscat Bailey A are two varieties to know first when exploring Japanese wine. This introduction follows their origins and international variety registrations, then explains why they appear often in award records alongside the way grapes are grown and named.

Why every entry has a source and a confirmation date
This site publishes verifiable facts with a source URL and a last-confirmed date. This page explains why blanks remain, why we do not yet publish winery photographs, and why the editorial team does not assign scores, alongside the current completeness of each field.

How are wine regions defined?
The wine regions on this site are not boundaries we drew from a map. We list only divisions actually used by national, prefectural, municipal, or regional government bodies, with their source and covered area made visible.

How we verify that a shop carries a wine
We record who says that a shop carries a Japanese wine and where that statement is published. This page explains the inclusion rule, what the source tiers mean, and why stock should be checked with the shop before a visit.

What this site does not publish
A database’s reliability is shaped not only by what it publishes, but also by what it leaves out. This site does not collect every piece of information that might be found. It accumulates decisions not to fill a field for appearance when its source, rights, or ability to stay current cannot be confirmed.

What a label can tell you — labeling rules for Japanese wine
The name of a wine alone may not tell you its grape-growing place, variety, harvest year, or use of imported ingredients. A National Tax Agency notification sets out what may be shown when specified conditions are met and where ingredient information is displayed. This article keeps the definition brief and focuses on how to read a label.

Measuring the overlap between three wine competitions
Japan Wine Competition, the International Wine Challenge, and the SAKURA Awards have different scopes and judging contexts. Matching their results to the same producer IDs reveals where their award records overlap—and which producers appear in only one of them.

Japan Wine Competition awards by prefecture
This view reads the long-running public results of the Japan Wine Competition through the spread of producers with awards, rather than award counts alone. Comparing that with the producers listed in each prefecture shows how widely the records are distributed.
Data ／ 2026-08-26
Counting varieties that appear in award records
We scan award-winning wine names for grape-variety names to see which varieties appear in the Japanese wine award data. Because wines that do not name their grape cannot be detected this way, the table is a verifiable lower bound, not a measure of total use.
