Mugizakkoku Kobo's "Spring Stream" Tapped at Bar So-ma in Tobu Nerima, a New Spring Guest Keg
The beer pub Bar So-ma Tobu Nerima in Tobu Nerima has welcomed a guest beer from Saitama's Mugizakkoku Kobo: "Spring Stream." In a post on March 23, 2026, it was introduced as a refreshing beer with a light, rice-derived character and citrusy aroma.
Hop BroMugizakkoku Kobo's Spring Stream has been tapped at Bar So-ma in Tobu Nerima. Just the spring-like name makes me want another glass already.
MugiWait, Spring Stream is the name of a beer? That's so stylish it feels like a classical poem!
Hop BroExactly. It's a guest beer from Mugizakkoku Kobo in Saitama. Places like Bar So-ma that rotate kegs are what make these one-time encounters fun.
MugiSo guest kegs mean the shop's limited-time slot, right? Suddenly it feels like a live concert venue, and now I'm excited!
Hop BroThat's the idea. The key point this time is its rice-derived lightness, so it seems designed to go down smoothly without feeling too heavy.
MugiOhhh, rice can make that much of a difference? It gives me this soft and light image, like it would suit a spring afternoon!
Hop BroThe post also called out the citrusy aroma as a highlight. When the hop character is clean, the aroma comes through first and makes the palate feel brighter.
MugiCitrus means, like, orange-ish? Does it make beer feel almost like a juice-like drink?
Hop BroNot juice, exactly, but the aroma can give a similar impression. True to Mugizakkoku Kobo's style, the nice part is that it shows the character of the grain while still being easy to drink.
MugiIf I drank it slowly in the basement at Bar So-ma, it would really feel like a spring glass! News like this makes me want to keep following new arrivals.
Hop BroIf it's connected right now in Tobu Nerima, that alone is a good reason to go. I want to put it in my first-round pick for today, and you should come drink with me too, Mugi.
MugiI'm in! The phrase the beer that's connected right now just sounds delicious. I can't wait to meet Spring Stream in a glass!
