The area with the largest concentration of JETs, Seibu is an incredibly diverse place. It features a wide variety of geographies, from vibrant downtown cores, to gentle rolling countrysides, to reclusive stretches of wilderness. This region contains the cities of Takasaki, Tomioka, and Fujioka, as well as the smaller communities Kanna, Kanra, Shimonita, Ueno, and Nanmoku. Whether you enjoy shopping, hiking, sightseeing, or just hanging out there’s always something to do in Seibu.

Weather in Seibu is mild and relaxed. As most of the region is a large open plain at the bottom of Gunma’s mountainous bowl, we get some positives and negatives. We have wet, scorchingly hot summers (with temperature in the mid thirties), pleasant falls and springs, and cold winters (ranging between -5 and +15, though the lack of insulation in most homes means you really feel it). Rainfall is fairly predictable, meaning that if the weather report says it’s going to rain at a certain time, it probably will. We get very beautiful (and loud) thunderstorms in the summertime, and lightning strikes on buildings are not uncommon – so we recommend buying some powerbars with surge protection if you have any electronics you’re attached to. The weather here makes Seibu a perfect site for recreational activities, sightseeing, and hanging out.


Seibu is Gunma’s transportation hub. We have the main connections with the Shinkansen at Takasaki station (Hokuriku and Joetsu lines,) and a well developed network of roads with access to both the E17 and E18 highways if driving is more of your thing. Our regional train system is perhaps lacking in comparison to the rest of Japan, but we still have a fully functioning network that can take you anywhere you like within the prefecture (and without, given some connections.) Just don’t miss your train or you might find yourself waiting up to an hour for the next one depending on where you’re headed. We also have a number of well-developed bus systems within our municipalities and across the prefecture (including the hilariously named Gun Bus.)
