Obata Castle Town
— Kanra's samurai quarter along an Edo irrigation canal
A castle town in the Gunma hills whose Edo layout is still legible on the ground: a stone-walled samurai lane, restored residences you can enter, and an open irrigation canal that still runs through the middle of the town.
- FromTakasaki Station
- ~40 minJoshin Line, then bike or taxi
- Get off atJoshu-Fukushima Station (Joshin Line)
- From there
- Obata Castle Town
The sweet spot
Obata is not a secret. The town signposts a walking route through it and keeps free parking at the garden. It is simply small and slightly off the rail line: the nearest station is a single-track local stop a few kilometres out, and most people visiting this corner of Gunma head for the silk mill at Tomioka instead.

How to actually get there
- Takasaki Station to Joshu-Fukushima Station (Joshin Electric Railway, about thirty minutes).
- Joshu-Fukushima Station to Obata (about 3.7 km, by free rental bicycle or by taxi).
- Follow the canal into Nakakoji lane and visit the Matsuura and Takahashi residences.
- Walk up to Rakusan-en at the top of the slope, then return the same way.
- Joshin Line from Takasaki Station
- Takasaki Station to Joshu-Fukushima Station on the Joshin Electric Railway, about thirty minutes on a single-track local line from platform 0. From the station Obata is roughly 3.7 km, covered by taxi or on one of the bicycles the station lends free of charge.
- Return from Joshu-Fukushima Station
- Cover the 3.7 km back to the station by bicycle or taxi and take the Joshin Line to Takasaki. This is a rural line with a thin evening timetable and no late service, so fix your return train before you set off, and do not count on a taxi waiting at the rank.
About the place
Obata lies in the hills south of Takasaki, in the small town of Kanra. It was the seat of a twenty-thousand-koku domain, and for a castle town of that size the Edo street plan survived unusually well: a walled lane of samurai plots, a daimyo garden at the top of the slope, and an open irrigation canal running through the middle of everything. That canal, the Ogawa-zeki, is not a restored feature. It is a working channel, listed among Japan's hundred famous waters and registered by the International Commission on Irrigation and Drainage as a heritage irrigation structure. The town reads as one continuous piece rather than a set of separate sights.
How to enjoy it
Start at the canal and work uphill: the lane, the two residences, then the garden at the top. The order earns its keep, because the water explains the plots and the plots explain the garden. At an easy pace it comes to about an hour and a half. Cherry trees line the canal and are usually at their best from early to mid April.
Background & history
Obata became a domain seat early in the Edo period, granted to Oda Nobukatsu, the second son of Oda Nobunaga. The jinya, the domain's residence and administrative office, was completed in 1642, and the stone wall that still holds the north side of Nakakoji dates from the same works. The Oda held Obata for generations before the Matsudaira took over, but the founding order never changed: the water was laid first and the plots were cut around it. That is the ground plan you walk today.
Before you go
- Cash
- The Matsuura residence is free to enter. Rakusan-en was listed at 300 yen for high-school age and above, free below junior-high age, and open 9:00 to 17:00 from March through October and 9:00 to 16:00 from November through February when checked. Joshin Line tickets are bought at the station, so carry some cash.
- Before you go
- The walk is flat and paved but almost entirely outdoors, with little shelter along the canal. The garden closes earlier in winter and shuts over the New Year period. Some stretches of the canal bank have low unfenced edges, so keep children close to the inside of the path.
- Another way
- By car it is about ten minutes from the Tomioka interchange on the Joshin-etsu Expressway, and about five kilometres from the Kanra smart interchange. There is free parking at the garden, and the town sets the start of its signed walking route at the Michi-no-Eki Kanra roadside station.
- After you get off
- From Joshu-Fukushima Station head south-west on the road toward the town office. The castle-town district begins where the canal appears alongside the street, and the garden is at the far, uphill end. Ask at the station window about the free bicycles before setting off, as some stretches of road have no footpath.
