Bandoko Garden, Ocean-side garden in Wakayama, Japan.

Bandoko Garden is a lawn garden on Bandoko-no-hana, the cape at the western tip of Saikazaki jutting into Wakaura Bay in Wakayama. The cape held a Kishu Domain lookout post over the sea in the Edo period, and the garden was laid out on the site of that post. From the lawn the view opens onto the Kii Channel and the islands of Oshima, Nakano-shima and Futago-jima.

During the Edo period, this location served as a strategic watchtower for the Kishu Domain to monitor foreign vessels in Wakaura Bay. The site was later transformed into a garden, merging its historical function with landscape design.

The garden occupies the site of a watch post (bansho) that gave the cape its name, Bandoko-no-hana. It is included in Wakayama City's Manyo poetry tour and in the Setouchi Dream Sea Route 50 Views. Visitors come for the view of the Kii Channel islands and for sunsets.

Opening hours are 8:00–17:00, but from April to August they shift to 9:00–18:00. The garden closes in rain. From Saikazaki Yuen bus stop, reached by the Saikazaki loop bus from JR Wakayama or Nankai Wakayamashi stations, it is about a 15-minute walk. The cape is exposed to wind and sun.

The three islands in the Kii Channel are Oshima (Male Island), Nakano-shima (Female Island) and Futago-jima, seen directly from the cape. The garden's headland, Bandoko-no-hana, was named for the Edo-period watch post of the Kishu Domain, and the site is listed among the 50 views of the Setouchi Dream Sea Route.
