Can anyone recommend budget-friendly temple tours or experiences that offer deep insights into Osaka's traditional heritage? I'm looking to balance cost-effectiveness without compromising on the authenticity of the experience. Any tips on how to save money while indulging in the historical significance of these temples? Your recommendations and money-saving strategies would be much appreciated! Thank you in advance!
