Fasionable bum-bag/fanny-pack/cross-body bag?

Going on a city break to Tokyo soon and don't want to carry a whole backpack around especially if it's crowded.

I don't want it to look like a roadman sash nor look like a tourist who's gotten lost on their way to the all-inclusive buffet!

Maybe a small camera bag or a waist pouch and water bottle holder?

It’s still winter so presumably you’ll be wearing an overcoat of some sort, and possibly a tailored jacket underneath. What do you need to carry that won’t fit in all those pockets, not to mention your trouser pockets? Only you can know.

And why a water bottle? Again, Tokyo in winter. It’s not hot, and water is readily available.

Ok. You said “soon” so I figured like now. May/June is spring and not generally hot there, albeit not overcoat weather.

To me, a lightweight tailored jacket in, say, a linen/wool/silk mix would give you enough pockets to carry a phone, wallet, notepad and other small things and be a better long-term wardrobe investment than a pack you might be unlikely to use much.

Or consider something more fashion forward like the sort of big-pocket cotton chore jackets and overshirts popularized by Japanese streetwear brands—you can buy something over there. For that matter there are lots of cool Japanese handbag makers to shop for in country. I like the look of South2 West8.

But it depends on your lifestyle and, above all, what you need to carry. I would still ditch the water bottle.
