Marketing is about being visible with great products and services in the places that your customers search or spend time. It varies massively for B2C and B2B, plus what type of service or product you sell has a large bearing too.
There's nothing wrong with having a social media presence and posting occasionally, in fact it builds trust and visibility, but for some businesses its a waste of time for generating leads or sales. Social media isn't an entity, Facebook will work for some B2C, TikTok for others and LinkedIn often for B2B.
The whole process needs to be done the other way around, with market, product/service and customer research first, plus it's hugely budget dependant. Just because a competitor that's venture capital backed, or has a huge marketing budget does Facebook ads is not a reason for you to start doing them. They may have a far better conversion rate and ROI from every other channel, with Google PPC, SEO or TV their primary marketing channels.
This all needs testing, tracking and scientific analysis, to work out whether any time or budget is worth it in each area. This is eminently possible, even for small businesses, but most people never do it because they don't know how or wont spend money on research, tracking etc, meaning they conclude it doesn't work.
If your industry is about being first to market or creating a buzz around new product launches, but you cant get access to the products, it will be very hard to create an audience and sales from that angle.
I'd be looking at can you leverage that interest and potentially get access to some products early to create that buzz; e.g. a trip to Japan at launch season or an expo (if there's such things), can you be first to market sometimes, can you get exclusives if you take a large volumes initially, can you take pre orders off the back of knowing something is coming?
