Three interesting yet completely unrelated sites. First up is a Yogurt Factory (ヨーグルト工房) where you can see how they make yogurt and then taste it, too. From there, the Toy Museum (おもちゃの宿) has displays of traditional Japanese toys and some for children to play with. Finally, there is the Killifish Research Center (めだかの学校), which studies the fish of the same name. Yahata no Sato is most enjoyable for those travelling with kids, particularly if they understand Japanese.

くぼ農園
Okayama is known throughout the county for producing some of the most delicious fruits Japan has to offer. Most visitors are aware of the local peaches, but the Japanese will often cite Okayama's muscat grapes (葡萄 Budō) as its premier offering. Visitors can tour the farm to see how the grapes are grown and harvested. You are also permitted (and even encouraged) to eat as much as you like, making a tour of the farm as delicious as it is interesting! Although the grapes are the star attraction, you can also see the harvesting of shiitake mushrooms, persimmons, sweet potatoes, and chestnuts. Visitors are also permitted to picnic and camp here.
招き猫美術館
A museum devoted entirely to the famous good luck cats seen in many shops and restaurants throughout Japan.
桃太郎温泉
A decent onsen with some jacuzzi-style baths inside and a rotemburo (outdoor onsen). There is a hotel here, too, for those who really want to relax.
