The Old Merchant House was Kanazawa's leading Chinese medicine shop in Minami-machi during the 18th century. The shop was established in 1759 and provided medicine for the feudal leaders. The merchant's family was given high status by the elders of the town. The shop was instrumental in maintaining the elegance of the tea ceremony, flower arrangement, and haiku during the time period in which it was open. The shop has a bridal exhibit on the second floor with examples of bridal gifts and a large flower arrangement made entirely out of sugar.

Nagamachi Buke Yashiki or 長町武家屋敷
Towards the coast from Oyama Shrine, this is an area of a few streets where considerable effort has been expended in order to recreate the feel of the samurai housing areas. The fact that almost none of the actual samurai houses remain does little to daunt the enthusiasm of the tourists. While historically dubious, it is a pleasant area to stroll, and one of the best of the remaining samurai districts in Japan. In Nagamachi, the Nomura House is open to the public (¥500), and boasts a small but exquisite garden. A short walk from there the city has relocated and restored two ashigaru (足軽: the lowest rank of samurai) houses that are open for free, and provide a lovely place to rest and enjoy the peace of a traditional Japanese house. Towards the Asano River to the north, there are a couple more samurai houses, not preserved or set aside as museum pieces, but actually lived in (and not open to the public).
石川近代文学館
09:30-17:00 (last entry at 16:30). Housed in the Meiji-era brick building of the former Fourth High School (preparatory schools for the Imperial Universities), the fore-runner of Kanazawa University, it houses displays relating to famous local (generally) authors from the Meiji to pre-war period. Probably only of interest to students of Japanese literature rather than casual tourists, as many of the displays are original copies of books or manuscripts, written in Japanese. ¥400.
神明宮
This shrine is famous for the more than 900-year-old Zelkova tree (keyaki) in its grounds. The shrine used to be on the banks of the Sai River, before land was reclaimed, and the tree was used as an anchor point for boats. Iron bars driven into the trunk so that boat hooks could be attached are still visible half-way up the tree. The rest of the grounds are used for parking and you will be kept at a safe distance from the tree by 3 fences: one bamboo, one steel and of course one made of concrete!
尾山神社
Built in the early Meiji period to honor the founding father of the Kaga Domain, Maeda Toshiie. It is notable for a unique gate with stained-glass windows that is a fusion of Japanese and Western architecture. The back gate to the shrine is also one of the few remaining parts of the original castle: a gate from the palace compound that escaped destruction when it was moved to the shrine. "Oyama" was the original name for the hill on which Kanazawa Castle was built.
にし茶屋街
The "west" to Higashi's "east", this is another district of restored geisha houses. This is considerably smaller (and quieter) than Higashi, with effectively just a single street, and aside from the (free) information center it's not possible to formally visit any of the houses. One can however enter the several shops that dot the street and appreciate the inside of these beautiful houses.
金沢21世紀美術館
Located across from Kenroku-en, this modern marvel offers a fascinating juxtaposition to the traditional splendour of Kanazawa. Even if you don't enter the permanent or temporary exhibitions, the building itself is worth a look and there are usually some free exhibits inside. Some of the permanent collection can be seen for free. These include pieces by Jan Fabvre (an impressive statute on the roof of the building), the famous "swimming pool" by Leandro Erlich in the main courtyard inside the building as well as playful pieces in the garden surrounding the museum. Don't miss the cafe!
