Izumise Co., Ltd. (Headquarters: Shimogyo-ku, Kyoto; President: Naotaka Totsuka), which operates over 50 specialized online liquor stores and handles product development and web production for alcoholic beverages, announces the launch of 'Weekend Cellar Set ~NAOTAKA Selection~', a blind wine set curated monthly by JSA-certified sommelier Naotaka Totsuka, who holds titles from the Order of Champagne and the Order of Bordeaux. The product will be available starting Sunday, July 5, 2026, through its store 'CAVE de L NAOTAKA – Premium Wine Specialist'.

We propose a new, time-efficient lifestyle that transforms the time spent 'wondering which wine to choose' in an information-saturated era into 'enjoyable discovery time,' enabling customers to encounter hidden gem wines from around the world—all from the comfort of home.

A New Purchasing Experience, Guided by Wine Professionals

While the rise of e-commerce has made tens of thousands of wines easily accessible, the overwhelming number of choices has led to an increasing number of consumers who end up 'always picking the same wine'—a phenomenon we call 'wine lost.'

Amid growing awareness of 'Taipa' (time performance), which emphasizes efficiency, we have designed this service to 'eliminate the stress of choosing and maximize the joy of discovery.' This is not just a bulk sale, but a new purchasing experience where wine professionals guide customers to 'the one truly worth drinking right now.'

'Contents Are a Secret'—The Thrill of the Unknown Until the Box Is Opened

The defining feature of this set is that the contents are completely undisclosed in advance. This is an intentional effort to remove biases such as brand reputation, label fame, or online ratings, allowing customers to purely enjoy the taste and the excitement of new discoveries.

The contents remain a surprise until delivery, but each month features a seasonal 'theme.' For the inaugural July edition, all courses except the Casual tier will receive a 'Curated 4-Bottle White Wine Set'—perfect for refreshing the body during the hot summer months.

From hidden gems in renowned regions to rare producers not yet available in Japan, the sommelier's expert selection delivers delightful surprises. In the future, we plan to expand the service to allow customers to customize their courses based on preferences such as red, white, or sparkling wines.

Limited to 10 Days per Month: A Flexible, No-Commitment Subscription Model

Orders for this set are accepted only during a 10-day window each month—from the 5th to the 15th—and each month features a different theme and wine selection.

While it offers the excitement of a monthly subscription with fresh experiences, there are no typical 'minimum commitment periods' or cancellation fees. Customers can freely choose to 'indulge with Premium this month,' 'take a break next month to save,' or 'switch courses as seasons change,' aligning perfectly with their lifestyle and budget. By removing the psychological barrier of subscriptions, we make it easy to enjoy premium wine experiences only when desired.

Four Courses for Every Occasion: Restaurant-Quality Wines at Unbeatable Value

To meet diverse needs—from everyday enjoyment to special treats—we offer four courses ranging from Casual to Luxury.

In every course, the total retail value of the included wines exceeds 1.5 times the set price.

We deliver a high-quality wine experience comparable to or better than restaurant offerings, made possible by our sourcing power as a specialized retailer—offering unmatched cost performance.
