Observe freshwater fish living in an unusual underground setting
About this spot
Oasa Roman Underground Aquarium (大朝ロマン地下水族館) is a unique aquarium in Oasa, Kitahiroshima Town. Tanks are lined up in a space resembling an underground mine tunnel, where you can observe a variety of creatures, mainly freshwater fish living in the Gono River (江の川) water system. It is an indoor spot where you can forget the heat above ground and stay cool, and the unusual display style captures children's curiosity. It is just the right break between the historical stroll and river play, a facility full of satoyama-style discoveries.

吉川元春館跡歴史公園は、戦国武将・吉川元春の居館跡を整備した歴史公園です。石垣や庭園の跡が残る園内は常時開放・無料で見学でき、戦国時代の暮らしぶりに思いを馳せながら散策できます。公園のそばを流れる志路原川は水がきれいで流れも穏やかなため、歴史散策の合間に気軽に水遊びを楽しめるのが魅力です。里山に囲まれた静かな環境で、歴史と自然の両方にふれられる1日のクライマックスです。
Tips
駐車場は公園入口にあり、無料で利用できます。志路原川は場所によって流れの速さが変わるため、小さな子どもは目を離さないようにしましょう。すべりにくい川用シューズがあると安心です。
Tips
Many areas inside have dimmed lighting, so holding hands with small children while moving around is reassuring. The interior is cool, making it a valuable rest spot in the hot season.
