Ota rewards travellers who arrive with a plan rather than a checklist. The city spreads out from its downtown, and the places worth your time sit at the edges of it: a temple founded in 1618, a castle ruin on a wooded summit, an ancient burial mound, and a hot spring district with a snake centre attached to it. Getting between them takes a little patience, but each one is substantial enough to justify the trip.
This guide suits travellers who are already in the region and want a day or two of history and hot springs rather than a full itinerary of its own. It covers the sights named in the source material, in the order that makes the best use of your time, followed by a one-day plan and answers to the questions visitors ask most.
Top things to do in Ota
1. Kanayama Castle
A Kamakura-era castle on the top of Mt. Kanayama, which rises to 244 m. The site sits 3.2 km north of the downtown, and the climb to the summit is the point as much as the ruins themselves: you are walking up a mountain that once carried a castle, not touring a reconstructed keep.
Go earlier in the day so you have daylight for the ascent and the walk back down. Because it lies north of the centre, it pairs naturally with the other northern sights rather than with the hot springs in the opposite direction.
2. Daikoin Temple
A temple founded in 1618, known to locals by the nickname Kosodate Donryu, meaning kid-raising Saint Donryu. It stands 2.4 km northwest of the downtown, close enough to reach on foot if you are comfortable with a longer walk.
Combine it with Kanayama Castle if you are heading north anyway, and check the layout before you set out so you are not doubling back through the centre. The temple's nickname is worth knowing, since it is how many people in the area will refer to it.
3. Yabuzuka Onsen
Ota's hot springs, in an area that was originally the Yabuzukahoncho Town area before it was annexed by Ota. It lies 9.7 km northwest of the downtown, which makes it the furthest of the main sights and the one that most rewards being treated as the end of your day rather than a stop in the middle of it.
Plan your transport before you go, given the distance from the centre, and leave yourself time to soak rather than arriving and turning straight around. The Snake Center is in the same area, so the two are best done together.
4. Snake Center
Located in the Yabuzuka Onsen area and known for its collection of rare kinds of snakes. It is the kind of place that appeals to travellers who want something specific and unusual rather than another temple or viewpoint.
Visit it on the same trip as Yabuzuka Onsen, since they share a location, and allow for the fact that the two together fill a good part of a day once you account for getting there and back.
5. Tenjinyama Kofun
A large ancient burial mound dating from around the 5th century. It is a burial mound rather than a museum or an interpretive centre, so the experience is the earthwork itself and the sense of age that comes with standing at something built so long ago.
Read up briefly before you arrive so you know what you are looking at, and treat it as a quiet stop rather than a long one. It works well as a shorter item on a day that also includes the temple and the castle.
If you only have one day
Morning: Start with Daikoin Temple, 2.4 km northwest of the downtown, while you are fresh. From there, continue to Kanayama Castle and make the climb up Mt. Kanayama to the Kamakura-era castle site at the top.
Afternoon: Head for Tenjinyama Kofun and spend some time at the burial mound. Keep this stop short, then begin the journey northwest towards the hot springs, since the distance is the largest single leg of the day.
Evening: Finish at Yabuzuka Onsen, with a visit to the Snake Center in the same area if you still have the energy and the time. Ending the day in the hot springs, 9.7 km northwest of the downtown, means the long trip out is also the reward.
