'Tokoh' means prominent, renowned figure, so a visitor to the museum might expect to learn about several of the leading political, social, business and/or religious figures in the city's development.
Not really, in this case.
The Museum's ground floor mostly celebrates the early 20th century constitution of Johor within the Federated Malaysian system, which is still in effect today. It goes into some detail, with historical manuscripts and even lists of the people involved in drafting it (which apparently included a UK law firm with a Singapore branch office); an impressive amount of attention and historical documentation for a provincial-level 'constitution' that probably nowadays has only as much legal effect as any other piece of legislation in Johor. The upper floor focuses obsessively on a couple of obscure literary and educational figures but there's not a whole lot there about the social, economic or cultural development of the city. For some reason some antique 1950s Singer sewing machines occupy pride of place in the ground level lobby area.
It's a beautiful old building in excellent condition, with the dim lighting and various passages providing a feeling of something unexpected lurking around the many corners and alcoves. The air-conditioning can be a welcome relief depending on the weather. Entry to the museum is free.
