Are Shiba Inu high maintenance?

Could you please elaborate on whether Shiba Inu dogs require a high level of maintenance? I'm considering adopting one, but I'm concerned about the time and effort it might demand. Are they known for being particularly demanding in terms of grooming, exercise, or dietary needs? I'd also like to know if they tend to have any specific health issues that might require frequent vet visits. Thank you for your insight.
