RIVERSIDE CLUB: Food, Art & Music Culture Come Together in Nakameguro’s New All-Day Lounge
RIVERSIDE CLUB officially opened on the first floor of “THE WORKS” along Meguro River in Tokyo on July 17, 2020. An all-day lounge which can be enjoyed from breakfast to dinner, its concept is a fusion of food, art, and music cultures which it calls “GOOD CULTURE SALON.”
RIVERSIDE CLUB boasts an incredible menu forged by chefs at the forefront of Tokyo’s food culture. Meals can be enjoyed while gazing at the various artwork on display, and customers can look forward to seeing collaborations with numerous apparel brands. It’s a unique space designed by adults for adults, the likes of which has never been seen before.
Comfort food is at the heart of RIVERSIDE CLUB’s menu design which they have cooked up using their own unique vision.
For breakfast, customers can enjoy a healthy smoothie made from a blend of kale, pineapple, kiwi and avocado. If they’re looking for something more classic, they can order the avocado toast served with bacon and eggs, or cold-pressed juice by SUNSHINE JUICE which hails as Japan’s first shop specialising in cold-pressed juice. The thought behind the morning menu is making sure to get both a tasty and nutritional meal down customers even if they’re in a rush.
If customers are looking for something a bit more hearty in the morning then they can check out the all-day menu where they’ll find the lounge’s fat and juicy 100% beef “RIVERSIDE BURGER.” There’s also the “Lemon Rice” provided by LEMON RICE TOKYO, a popular Shibuya-based restaurant owned by Yuhi Komiyama, the vocalist of Hoff Dylan and known as the gourmet chef of the music industry. Everything on the menu is made with Tokyo’s food culture in mind, and if you’re looking for something very Tokyo-esque, then there’s the “Hamburger Naporitan,” a bed of spaghetti topped with a hamburger.
Popular foods from NAKAMURA GENERAL STORE will also be served, such as scones, carrot cake, apple crumble, lemon pie, and more. NAKAMURA GENERAL STORE is a popular Hawaiian bakery which was originally in charge of pastries served at Diamond Head Market & Grill, which is famous for its Hawaiian lunches and scones, but subsequently opened its own store in Kyoto and became so popular that it often sells out its stock by evening time. Coffee made using specially selected coffee beans provided by Minami-Aoyama-based coffee rosters will also be served and goes perfectly with NAKAMURA GENERAL STORE’s food. Customers will be able to order their own coffees or buy their own bag of beans to take home.
RIVERSIDE CLUB has collaborated with numerous artists for graphics on show there. Their logo was created by “& Supply,” a Tokyo-based creative studio. Various artwork will be displayed, including a photograph of Lady Gaga taken by Nobuyoshi Araki for a bondage-themed photoshoot in Vogue Hommes Japan. Pieces by LEEGET, who creates graphics and illustrations, will also be displayed. RIVERSIDE CLUB will continue to serve its “GOOD CULTURE SALON” theme by promoting more artwork in the future.
RIVERSIDE CLUB also allows pets, so customers can enjoy a quiet time with their furry comrades. Pets will get their own pet-friendly menu, toys, and more in the future.

Long-Standing Kyoto Tea Wholesaler Yamamasa Koyamaen Opens Cafe in Tokyo
TZEN, a company dedicated to promoting traditional Japanese culture around the world, has teamed up with Yamamasa Koyamaen, a tea wholesaler in business since the Edo period, to open a new matcha cafe in Tokyo!
ATELIER MATCHA, a quick walk from Ningyocho station, is harnessing the concept of ‘the third wave of matcha,’ serving up premium matcha in a cozy atmosphere.
MATCHA Cookies & Cream Shake: ¥748 (Tax Included)
MATCHA with Warabimochi and Red Bean Topping: ¥748 (Tax Included)
MATCHA Jelly Cider: ¥660 (Tax Included)
MATCHA Granola and Yogurt Latte: ¥715 (Tax Included)
MATCHA Cotton Candy Milkshake: ¥748 (Tax Included)
MATCHA Affogato: ¥660 (Tax Included)
MATCHA Shot (Espresso Style): ¥220 (Tax Included) / MATCHA Water: ¥275 (Tax Included) / MATCHA Green Tea: ¥330 (Tax Included)
Supreme MATCHA Terrine: ¥660 (Tax Included)
(This is a partial menu, all prices are for those dining in.)
Matcha is becoming popular around the world. ATELIER MATCHA was created to offer customers a unique experience which showcases the true taste and culture of this beloved tea grown in Japan.
Yamamasa Koyamaen is a Kyoto institution, cultivating and grinding matcha tea leaves for 160 years. Over 1,000 tea retailers, department stores, domestic and international trading companies and hotels stock their high-grade matcha, gyokuro, sencha, and other specialty teas, making them one of the most recognized and respected names in this traditional Japanese art. The company even prefers to call themselves a ‘studio’ rather than a ‘factory’, using the 800-year history of tea cultivation in Uji, Kyoto as a starting point to create their masterpieces.
ATELIER MATCHA is Yamamasa Koyamaen’s first cafe, and also the company’s first experience selling directly to consumers.
Blending the highest-grade matcha with locally made sweets, the cafe hopes customers will enjoy these original creations while surrounded by the relaxing aroma of tea.
The matcha used in the cafe includes signature Yamamasa Koyamaen blends, including Ogurayama and Tennozan, both varieties often used in tea ceremonies. For a limited time, the cafe is offering a single-origin blend with one rare variety of matcha, as well as a beverage made with tencha, which are the leaves used to make matcha before being ground down in a stone mortar. Visitors can also enjoy gyokuro and hojicha teas, made from carefully selected leaves.
Pulling recipes from Yamamasa Koyamaen’s book ‘Kyoto Uji-Koyamaen: Simple Matcha Drinks to Enjoy at Home,’ the menu features refreshing drinks blending the traditional with the modern, with unexpected combinations of soda, fruit and yogurt. Seasonal drinks will also be making an appearance, including shaved ice in summer and chocolate drinks in winter.
The name MATCHA SHOT packs a punch, using matcha instead of espresso for a needed pick-me-up. MATCHA WATER, a refreshing cup of watered-down tea, offers a way to fully enjoy the fullness and more hidden flavors of this popular Japanese tea.
As expected, ATELIER MATCHA also has a sweets menu set to impress: these sweet treats feature only the best, created with the top 0.03% of total national matcha production. This insanely high-quality matcha is a part of Yamamasa Koyamaen’s ultimate matcha experience project, titled “ALL FOR ONE,” which provides these rare leaves to some of the country’s top professionals in various fields.
At opening, only limited qualities of the Supreme MATCHA Terrine, made by well-known pâtissier Toshi Yoroizuka, will be available.
These authentic matcha creations are perfect for a hot summer’s day, or as a gift for a friend. When in Tokyo, don’t miss it!

Art For Social Change Project Launches in Japan Using Waste to Create Art
29.July.2021 | FASHION
Innovation Design launched its new ‘Art For Social Change’ project at haishop in Shibuya Scramble Square on July 21 which sees artwork made from waste.
According to Japan’s Ministry of the Environment, 42.74 million tonnes of garbage has been thrown out since 2019. That’s the equivalent of around 115 Tokyo Domes, or 918g of waste per person everyday. The waste cannot be exported, and so real action is required to reduce the amount of waste create on the island country of Japan, especially when thinking 20 years down the road.
That’s where haishop comes in. Using caps from detergent, which are actually no longer sold, as well as plastic caps and other materials resulting from waste, it will create a new identity for waste together with consumers in the form of art. Art For Social Change aims to send a message to society to make real transformations in the world through the medium of art.
It’s easy to imagine what happens when creating a product up to its completion, but considering what happens to it after it’s been used is a lot more difficult. Every year, the available capacity at final disposal sites decreases more and more. The important topic at hand is getting everyone in Japan to really treasure the products they buy, to conceive ideas on how to prolong longevity of the things that people purchase, and construct a new society centred on recycling and reusing. And this isn’t just a Japan problem – it’s a global one. That’s the message which Art For Social Change carries.
The only conditions on participating with the project is that you agree with its goal and that you use materials on sale at haishop. Everyone is invited regardless of age or gender.
The artworks in action
4th year students from Nitobe Bunka Elementary & Junior High School used waste materials to create ‘souvenir’ theme products which the children are helping to sell at the shop. The proceeds go back to the school itself while helping teach children about new ways of reusing and recycling.
