Step out of Kita-Koshigaya Station in April and the riverbank in front of you is lined with blossoming sakura trees. Walk about a kilometre along the water and you reach a park filled with the same flowering trees, which is the simplest and best introduction to Koshigaya.
The city sits in the flat Nakagawa basin in eastern Saitama Prefecture, about 25 kilometres north of Tokyo, and grew up as a post station on the Nikkō Kaidō and Ōshū Kaidō highways with a river connection to Edo. That history shows in its older places of worship, and its modern life shows in its shopping and its doll-making.
This guide suits travellers based in Tokyo or Saitama who want an easy half-day or full day out rather than a long-distance trip. It covers the sights and experiences the sources support, with practical notes on how to combine them.
Top things to do in Koshigaya
1. Sakura along the river near Kita-Koshigaya Station
In April, the river near Kita Koshigaya station is lined with blossoming sakura trees. This is the city's clearest seasonal sight, and it costs nothing but the walk.
Time your visit to April, and combine the riverbank with the park at the end of the walk rather than turning back early.
2. The park at the end of the sakura walk
A walk of about 1 km from the river near Kita Koshigaya station brings you to a park that has been filled with the beautiful flowering trees. It is the natural finish to the riverside stroll and the best place to stop and sit.
Do the walk in one direction and let the park be your destination, so the cherry trees are the whole point of the outing rather than a backdrop.
3. 久伊豆神社
久伊豆神社 is one of the specific places of worship in the city. It is worth the time as a quiet stop that reflects Koshigaya's long history as a settled area on the old highway routes.
Pair it with the rest of your day in the city centre rather than treating it as a separate trip.
4. 立正佼成会 越谷教会
立正佼成会 越谷教会 is the other named place of worship in the city. Visit it as a place of worship rather than as a sight, and keep your expectations accordingly.
Combine it with 久伊豆神社 if you want to see both of the city's named religious sites in one outing.
5. Aeon Laketown shopping mall
Aeon Laketown shopping mall is listed among the city's local attractions. Koshigaya is a major regional commercial centre, and this is where that side of the city is most visible.
It sits by Koshigaya-Laketown Station on the Musashino Line, so it works well as a stop on the way in or out rather than a dedicated trip.
6. Aritaki Arboretum
Aritaki Arboretum is the city's other listed local attraction. It offers a green counterpoint to the shopping and the riverside walk.
Give it its own slot in the day rather than squeezing it in between the shrine and the mall.
7. Daruma dolls
Koshigaya is famous for producing daruma dolls. Looking at daruma is one of the few things here that is genuinely specific to this city, so it is worth seeking out while you are in town.
Ask locally where daruma are sold rather than assuming a particular shop, and treat a daruma as a souvenir with a story attached.
8. The riverside setting itself
Many rivers flow through Koshigaya, including the Motoara River, Naka River, Ayase River, Furutone River and Sakagawa River. The city is flat, with an average elevation of only five metres above sea level, so the water is always close by.
Build a walk around whichever river is nearest your route, and remember that September is the wettest month if you are planning around the weather.
9. Koshigaya's post-station heritage
Koshigaya-shuku prospered during the Edo period as a post station on the Nikkō Kaidō and Ōshū Kaidō highways, and the town also had a riverine connection with Edo. Walking the city with that in mind changes what you notice.
Read up on the Nikkō Kaidō and Ōshū Kaidō before you go, so the streets make sense as a route rather than as scattered buildings.
If you only have one day
Morning: Start at Kita-Koshigaya Station and walk the riverbank lined with sakura, continuing about 1 km to the park at the end. In April this is the best possible use of your morning; outside April, do the same walk for the riverside itself.
Afternoon: Move on to 久伊豆神社 and 立正佼成会 越谷教会, then take in Aritaki Arboretum. Keep an eye out for daruma dolls while you are moving between them.
Evening: Finish at Aeon Laketown shopping mall, which is convenient to Koshigaya-Laketown Station on the Musashino Line for the journey onward.
