Hikari Miso Co., Ltd. (President: Yoshihiro Hayashi) is holding a tasting and special sales event for its new-sensation amazake HARE NOCHI KOJI at three hot bath facilities in Tokyo, starting today. It's a chance to casually try a refreshingly tangy amazake right after a bath.
HARE NOCHI KOJI is a new-sensation amazake with a refreshing tartness unlike conventional amazake. It draws out its bright acidity by using "white koji," a mold not typically used in amazake production. The lineup includes a concentrated type that can be mixed with water, sparkling water, and more for a variety of arrangements, and a straight type that can be enjoyed as is.

The HARE NOCHI KOJI Series
A new-sensation amazake with a refreshing tartness unlike conventional amazake
The biggest feature of the HARE NOCHI KOJI series is its sweet-tart flavor, unlike anything found in conventional amazake. To bring out its refreshing acidity, the drink uses "white koji," a mold not typically used to make amazake. The citric acid produced by the white koji lifts both body and mood in everyday moments. The lineup comes in two types: HARE NOCHI KOJI 340g, a diluted-style drink that can be mixed with sparkling water and other beverages to taste, and HARE NOCHI KOJI Straight 1000ml, which can be enjoyed as is.
HARE NOCHI KOJI 340g

A double-concentrate type that allows for a variety of arrangements. The taste changes depending on how it's mixed—with water, sparkling water, wine, and more—so it can be enjoyed in a style suited to personal taste and occasion. Arrangement recipes are shared on the official brand website.
- Volume: 340g
- Suggested retail price: ¥540 (tax included)
- Best-by period: 12 months*
HARE NOCHI KOJI Straight 1000ml

A ready-to-drink straight type that recreates the base flavor of HARE NOCHI KOJI 340g diluted 1:1 with water. Thorough mixing during production gives it a smooth mouthfeel and a clean, easy-to-drink taste, making it easy to work into a daily amazake habit.
- Volume: 1000ml
- Suggested retail price: ¥648 (tax included)

About the Bathhouses
Myohoyu

A two-minute walk from the north exit of Shiinamachi Station on the Seibu Ikebukuro Line, this renovated public bathhouse is known for its popular soft-water carbonated silky bath and sauna, drawing visitors from far and wide. The sauna is compact but runs at a high temperature of over 100°C (212°F). Towel, shampoo, and body soap rentals are available, so it's easy to drop in anytime.

Nippori Saito-yu

A three-minute walk from JR Nippori Station on the Yamanote Line, this old-town Tokyo bathhouse has no sauna but offers a wide variety of baths, with every tub using ultra-soft water, including a high-concentration carbonated bath and micro-nano bubbles. Water temperature is adjusted across four levels—39°C, 41°C, 42°C, and 44°C—letting visitors experience how the character of the water changes at each degree. Alternating between the hot baths and a cool bath of about 22°C offers a different kind of refreshed feeling than a sauna provides.
