Jones: It's the biggest
metropolis on Earth.

Nearly 14 million people
live here

in a city that never sleeps.

There's delicious street food...

...and a buzzing nightlife.

You're unlikely to be mugged,

and theft is rarely a problem.

Welcome to the world's
favorite capital,

where good etiquette
is always observed...

...and where humans
are only half the story.

♪

[Bird cries]

♪

From its humble origins
on Japan's east coast,

Tokyo has seen a few changes.

Once a small fishing village,

it has grown relentlessly

into one of the world's busiest

and most technologically
advanced mega cities.

Now a powerhouse of industry
and commerce,

it's better known for
its wild nightlife

than its wild animals.

But look beyond
the bright lights,

and it's apparent that Tokyo
also moves

to a different beat...

...a natural life cycle
that begins each spring

with an iconic spectacle.

♪

Cherry blossom, or Sakura,
is a national obsession.

But as well as
lifting people's spirits,

it's also a bittersweet
reminder.

For more than 1,000 years
the short-lived petals

have prompted the Japanese
to reflect

on the fleeting beauty of life

and to make the most
of the time they have.

♪

Life comes in many forms
in Tokyo.

Most people, though, are
probably unaware

of the animals
living in their midst.

♪

A distant relative of the fox,

the tanuki
is a type of Asian wild dog.

Japanese folktales are filled
with these shadowy creatures.

They typically appear
as mischievous shape-shifters

that love to trick humans.

In Tokyo, tanuki often make
their homes in storm drains

next to railway lines

and use the tracks
to roam the neighborhood.

[Dinging]

So long as they stay
out of sight,

the city is a reasonably
safe place

for tanuki parents
to raise their cubs.

There's really just
one serious hazard.

[Train whistle blows]

♪

Tanuki aren't renowned
for their speed,

but they've got
a keen sense of smell

and a dogged determination when
it comes to seeking out food.

The local shrine is always
worth a visit.

Shinto shrines are places
where people pay their respects

to the spirits,
with offerings of food and sake.

But this one is guarded by
a pair of fierce-looking foxes.

In their earthly form,
foxes are known to kill tanuki.

Perhaps on this occasion,

she should show some respect.

♪

[Clattering]

[Train whistle blows]

Around the corner, dad is
rummaging for a little treat

to take back to the kids.

♪

The cubs will soon be able
to forage for themselves.

But first they need to learn
how to cross the tracks safely.

After their snack,
they're ready for a lesson.

If they've got any sense,
they'll pay attention.

♪

Their lives may depend on it.

♪

[Train brakes screeching]

♪

[Dinging]

♪

Four of the cubs have made it.

But one has got distracted

and is lagging
dangerously behind.

♪

Tonight the spirits
have been kind.

♪

To survive in a city like Tokyo,

animals need more than just
a guardian angel.

Food might be plentiful,

but obtaining it requires
a bit of know-how.

With teams of street cleaners
working hard

to keep the place spotless,

life can be quite a challenge

for the city's
non-human residents,

many of whom rely
on our wastefulness.

To grab some takeaway
before it's taken away,

large-billed crows have to stay

one step ahead
of the waste collectors.

Their window of opportunity
is brief.

♪

Pickings are especially rich
after a Friday night,

when Tokyo's restaurants
have been busy.

Saturday mornings can even
bring the occasional steak.

♪

With half an eye
on the rubbish trucks,

the street-wise birds know
pretty much to the second

when their time is up.

[Indistinct talking]

[Siren wailing]

The crow's resourcefulness
isn't limited to getting food.

Spring is a time

the city offers
intriguing new possibilities.

Clothes hangers don't just mesh
nicely with traditional twigs,

they also add a touch

♪

Ever since it became
Japan's capital in 1869,

Tokyo has been spreading.

Now almost 100 kilometers
across,

it's a vast amalgamation
of over 50 towns and cities.

And yet somehow it contains
a wealth of animal life.

[Birds chirping]

One of the keys to this paradox

is something
distinctively Japanese.

Shinto, the way of the Gods,

is the original faith
of the Japanese people

and is as old as Japan itself.

[Doors squeaking]

It's based on a belief
in sacred spirits, or kami,

which can often take the form
of plants or animals.

♪

That's why Shinto shrines are
always associated with trees.

♪

Throughout Tokyo,
hundreds of small shrines

provide important habitat
for animals.

But the largest by far is
the Meiji Jingu Shrine,

right in the heart of the city.

Created in 1920 to venerate

Emperor Meiji and his wife,
Empress Shoken,

it involved the planting
of 100,000 trees

donated from all over Japan.

A century on, and this
self-sustaining forest

is now a quilt of over 230
different tree species.

The shrine attracts a constant
stream of visitors,

who come to ask for good fortune

alongside the priests
who worship here.

But all this human activity
is kept within narrow limits.

The 70-hectare sacred forest
that surrounds the shrine

is restricted access only.

And away from the crowds,
nature is left undisturbed.

As well as sheltering
woodland birds,

this thriving oasis is a haven
for countless insects,

rat-hunting snakes,

and an obscure pond dweller...

...the softshell turtle.

♪

For sheer beauty,
there's surely no contest.

Its wing covers have been used
to make necklaces and dresses

and even to decorate
a royal palace.

Such is the allure
of the Japanese jewel beetle.

♪

Beyond the sacred forest,
new kinds of green space

are popping up in the city.

Farms were once cleared
to make way for skyscrapers.

Now they're becoming part
of the urban fabric.

As well as providing food
and cooling the building

on which it sits,

this rooftop rice field
in Central Tokyo

is giving city kids a chance
to connect with nature.

Just like a traditional
paddy field,

this high-rise version
is teeming with frogs

that were brought here
in the soil.

[Indistinct talking]

Every spring,
farmers show the children

how to plant the rice seedlings.

[Indistinct talking continues]

Four months from now,
these budding urban farmers

will be back
to harvest what they've sown.

In Tokyo, space is at a premium,

which can leave many animals
without a home.

Along most of Tokyo's
waterfront,

factories, roads, and runways
have replaced natural beaches...

...and squeezed out
much of the wildlife.

Kitamura:
[Speaking Japanese]

Jones: Dr. Kitamura, who heads
up Tokyo's Little Tern Project,

is trying to ensure
that these endearing birds

still have enough space
to breed.

To give them a fighting chance,

volunteers have built
a six-hectare substitute beach

on the roof of a sewage works.

Building a beach
was just the start.

Now every spring
Dr. Kitamura and his team

have to persuade the birds
to use it,

and that requires
a bit of trickery.

[Speaking Japanese]

Jones: Guided by master
craftsman Haruo Uchiyama,

the children play their part

by making dozens
of lookalike little terns.

The finished decoys are
scattered across the roof,

and to complete the illusion
of a busy colony,

a large speaker plays
the sound of chattering terns.

[ Terns chattering]

Primitive though it is,
the birds fall for it.

Every year, up to 1,000 terns

are now choosing the roof
of the Morigasaki Sewage Works

as their breeding ground.

Flying in from Australia
and New Zealand,

some of these visitors
have already racked up

more than 8,000 kilometers.

♪

Males and females share the job
of incubating eggs,

which takes about three weeks.

♪

Within a month, the rooftop
is alive with tiny chicks.

♪

[Chirping]

♪

But this noisy nursery
is no playground.

Birds that nest on beaches,
natural or man-made,

are vulnerable
to sharp-eyed predators.

And with a brood
of its own to feed,

a kestrel has its sight set
on a baby tern.

♪

[Terns crying]

No amount of mobbing
can deter the predator.

Day after day,
the hunting kestrel returns.

♪

Having learnt
from previous years,

Dr. Kitamura and his team

now cover the rooftop
with little refuges.

The faster a chick finds cover,

the more likely
it is to survive.

Three weeks is all it needs.

As long the adults
keep bringing back food,

the young terns
will soon be big enough to fly.

♪

Giving them space to breed is
undoubtedly helping the terns.

Although some will struggle,
others will fledge successfully

and follow their parents
out to sea.

♪

Although little of Tokyo's
original shoreline is left,

the waters beyond
are still untamed.

And you might be surprised

♪

Few people alive
know these depths

better than Hiroyuki Arakawa.

Arakawa:

Jones: Fascinated by the ocean
since he was a boy,

he claims to have spent
more than three years

Nowadays, Mr. Arakawa's
main concern

is for those who earn
their living from the sea,

Tokyo Bay is known
for its deadly storms.

Over the years, Mr. Arakawa
has helped to recover

more than 100
drowned men and women.

[Clanging]

[Bells chiming]

Whilst he can pray
for lost souls

at his local Ahinto temple,

Mr. Arakawa wanted to do more.

So, with the blessing
of the priest,

he's built an additional shrine.

It's not exactly on Google Maps.

Hidden some 20 meters

the most dedicated visitors.

Twice a month,
dressed as a priest,

Mr. Arakawa drops in

to make a ritual offering
to the water gods.

is anyone's guess.

Before he surfaces, Mr. Arakawa

prays for the safety
of all those who go to sea.

Aside from facing storms,

fishermen in Tokyo Bay
have also been wrestling

with an unusual shark problem.

It's a problem that
dive operator Kan Shiota

knows all about.

Shiota:
[Speaking Japanese]

Jones:
As they thrash about,

trapped sharks damage
valuable fish like flounder,

which then go to waste.

Some frustrated fishermen were
starting to mutilate the sharks,

which is when Mr. Shiota was
approached with a novel request.

Using the fishermen's
unwanted catch,

Mr. Shiota set up
a shark-feeding station.

Before long, it was attracting
not just sharks,

but shark enthusiasts.

Believe it or not, there are
people willing to pay good money

to get nibbled by sharks.

[Gulls crying]

The feeding station is located
just offshore,

well away from
the fishermen's nets.

♪

The sharks that you're most
likely to encounter here

are banded houndsharks.

Typically, this shallow-water
species is nocturnal

and solitary.

♪

But since they're fed
twice a day,

the sharks tend to hang around.

♪

And encouraged by
regular handouts,

they've learnt to trust humans.

Known as the shark scramble,

this mass gathering
has to be one of Tokyo's

most amazing
wildlife spectacles.

The sharks are joined
by grouper...

...stingrays...

...sea bream...

of smaller fish.

Despite physical contact,

no shark or stingray has ever
harmed Mr. Shiota or his guests.

Just as importantly, though,

the sharks are no longer
a problem to the fishermen.

Not long ago, hundreds of
these amazing creatures

were being netted,

and some even suffered
the removal of their fins.

Today, the number of entangled
sharks is virtually zero.
