Long overdue.

For a country with limited resources and land.. Vertical farming, indoor farming is a good way to keep food security safe within Japan itself.

I’m glad that Japan is doing this too. I knew about vertical farming for a number of years now, and never even thought about Japan having it. Obviously a great idea, considering not only the aging population, but the very limited arable land available.

and with the technical capabilities of Japan, they can easily pull this off. And I’m glad they’re really making headway on this apparently.

Essentially the same story has popped up several times over the past decade. Nothing new here.

If they build underground it would take no space and less heating expense.

I'm all for cheap, quality vegetables year-round!

Hope the costs are reasonable. with some excess buildings in relatively central locations coming available, this may be good news.

Are they as tasty and also nutritious as outdoor produce? Safer because less or no pesticides are used? Why is that worker wearing a space suit and mask? Is sterility necessary?

Wait a sec, I thought people hated factory farms?

Price gone down. Not even.

World leader in vegetables export are the Netherlands after the USA, can you imagine ?

Japan can do 100 times better and could feed for cheap its population.

Guess who is impeding that from happening ?

I think the biggest advantage of vertical farming is that we can grow vegetables in the city center.

This may make it easier for e-commerce providers to supply on-demand vegetables to urban dwellers.

Wow, lettuce, tomatoes and some strawberries. That's great. You can feed a whole lot of people with those.

Guess what crops won't be grow indoors (using huge amounts of resources btw): potatoes, corn, wheat, beans, pumpkins, peanuts, eggplants, blueberries, apples, pears, okra, bananas, peaches, mangoes, radishes, onions, carrots, melons, rice, you get the point. Pretty much everything else that requires the Sun.

If all the old farmers are hitting the bucket or unable to do the work, maybe younger people need to reevaluate their lives and realize that someone has to grow the food they eat. Less time in the office and more time in the fields.

Globally renowned firms such as Panasonic, Toshiba and Fujitsu have tried their hand -- converting old semi-conductor production lines with varying levels of success.

Bare in mind that there is a considerable amount of investment required when setting up one of these facilities and is is extremely difficult to re-use an old building which has not been deigned from the beginning to have very tight environmental controls. The big three mentioned in the article above already have decommissioned facilities sitting idle which have paid off their initial investments.

The advantage with growing indoors is that the produce being grown has a known rate of growth etc, so they simply become a commodity. Buyers/sellers can lock in a price for the produce months in advance and know that it will be delivered on time without concerns about the weather affecting production.

Recent advances in LED's have also reduced the power required, as well has optimizing growing conditions.

It s just a tradeoff between

1) manpower + land vs

2) electricity & cost of capital

In most countries 1) is much cheaper

Once we get very cheap electricity like fusion and advanced automation with AI, vertical farming will be much more attractive.

You might want to educate yourself on container crops before making such a claim. A simple search online shows that plenty of crops can be container grown.

Also, all plants need light to grow and you can get that in greenhouses with special lighting.
