Hello!Today, I’d like to discuss the Phase 4-1 sales of Cielia Tower Nakanoshima(シエリアタワー中之島).
I’ve covered Cielia Tower Nakanoshima in several past articles, and sales have been going well!
Each phase has come with a price increase, so I had initially thought the last article would be my final coverage. However, a shift in the market has led me to analyze the Phase 4-1 prices for Cielia Tower Nakanoshima.
Here are the two key points that made me sense this shift:
- Some newly built condos are struggling in post-completion sales, causing developers to aim for a sell-out before completion.
- Some units have actually dropped in price compared to the previous phase.

Developers Targeting Sell-Out Before Completion Due to Struggles in Post-Completion Sales of Some New Tower Condos?!
Movement Among Some Suburban Condos
I’ve been posting about this on X (formerly Twitter) periodically, but some suburban new condos have been “discounting” in order to sell. Not only are they lowering prices, but an increasing number of new condos are giving out QUO cards or snacks as “model room visit perks” compared to last year, indicating how much these suburban areas are struggling with marketing and sales.Examples of new condo discount DMs and visit campaigns


Meanwhile, in many new high-rise condos in central areas, model room tour slots get fully booked immediately after being released, and some people can’t even get in to tour before the Phase 1 lottery. Despite the higher prices, they still sell. This really highlights the growing dichotomy in the market, where:
“Expensive condos in central areas still sell, while cheaper suburban ones do not.”
But even in these previously booming city-center towers, some subtle shifts are emerging.
Changes in Popular Tower Condos in Central Osaka?!
Brillia Tower Dojima(ブリリアタワー堂島) is being sold after completion with a major price increase, and it appears to be struggling quite a bit. Blogger Data-man recently posted about the so-called “Brillia Shock,” which generated quite a buzz.Here’s the Brillia Shock article
Strictly speaking, calling it a “struggle” might be an overstatement. The real situation is that units with severely obstructed views on the lower floors have been significantly marked up, and since brand-new but unoccupied resale units (with better views and cheaper prices) are also on the market, those resale units are selling first. Nevertheless, it does appear to be influencing various developers’ sales strategies.
A few years ago, the practice of gradually raising prices was mainly something you saw from Sumitomo Realty. But now, nearly every mid-size and large developer is using this strategy, raising prices with each new phase. Large developers, in particular, can afford extended sales periods even with price hikes due to their financial strength.
(Plus, the reality is that many popular condos still see lottery demand despite significant markups, and most sell out before completion.)
However, it seems that some developers are currently saying,
“Don’t drag out the sales; aim to sell out before completion!”
Thus, some companies have begun increasing the number of units offered per phase or becoming more cautious about price hikes.
(Of course, this doesn’t apply to every new condo.)
Post-Completion New Condo Sales vs. Resale Units
Besides Brillia Tower Dojima, Cielia Tower Osaka Horie(シエリアタワー大阪堀江) has also been selling newly built units post-completion, gradually marking up prices and releasing a few units at a time. They used to have some units go to lottery, but now there are some first-come, first-served offerings—an indication that sales have slowed.That’s because, even though a lot of brand-new, unoccupied resale units have already sold, there are still about 60 brand-new, unoccupied resale listings on the market as of mid-February 2025. Of course the newly built units with price hikes aren’t going to sell well in that environment…
(And with 60 such brand-new, unoccupied resale units, it’s hard to tell at a glance which are bargains and which are overpriced.)
Movements in the Infinity Pool Towers
Park Tower Osaka Dojimahama(パークタワー大阪堂島浜) also raised prices significantly from Phase 1-1, but recently hasn’t hiked prices for lower-floor units. It seems Mitsui Fudosan wants to sell off lower floors first. High-floor units with good views will likely sell post-completion at a high price once they can show people around an on-site model room, but lower-floor units may be harder to sell if they remain expensive once on-site tours start (though if the area or other features are very appealing, they might still sell)…Anyway, with that lengthy introduction, it seems Cielia Tower Nakanoshima has increased the number of units offered compared to the original plan for Phase 4 sales. They’ve added roughly 23 more units to the originally planned total, so it’s likely that the slower sales pace of newly built Brillia Tower Dojima nearby has had a sizable impact.
And the changes aren’t just about increasing unit counts…

Some Units Are Cheaper Than the Previous Phase!
Yes, some prices have gone down!They had been raising prices with each phase. However, units that didn’t get reservations in the previous Phase 3, or those on slightly lower floors than before, were not just left at the same price but actually discounted.
Of course, many units are still higher-priced than in the previous phase, but those likely to struggle in sales or priced too high saw a reduction.
(We’ve seen Park Tower Osaka Dojimahama(パークタワー大阪堂島浜) also do some alternating between raising and lowering prices in the past…)
Since I thought Cielia Tower Nakanoshima was doing well, this new pricing made me wonder if the “Brillia Shock” had an effect. The number of discounted units isn’t huge, but the markdown can be anywhere from 2 million to 14 million yen. These discounted units might be real opportunities during this Phase 4-1.
Personally, while I’m glad to see more attention on Osaka’s condo market as prices rise, it’s getting tough for real end-user buyers within the city. I’m also considering upgrading to a bigger place myself and honestly feel it’s gotten too pricey. So, I actually welcome a bit more of this downward movement.
For properties aimed at investors or the wealthy—like Grand Green Osaka(グラングリーン大阪)— developers can keep raising prices. But for those primarily targeting average salaried families and real end-users, I personally wish they’d keep prices in a more approachable range.
Still, in the Nakanoshima area, existing properties such as The Parkhouse Nakanoshima Tower(ザ・パークハウス中之島タワー) continue to sell even at skyrocketing prices, so by comparison, for Cielia Tower Nakanoshima, even though it’s a fixed-term leasehold, there may be some units that still look like bargains in today’s market.
(This is more of an end-user recommendation rather than an investment pick, though.)
Phase 4-1 Sales Prices
Let’s look at the Phase 4-1 selling prices by floor level.Keep in mind that they aren’t always selling the exact same floor in each phase, so the price increases/decreases can be a bit tricky to compare. I’ve tried to compare similar floors to show the differences in pricing.
Please note that not all units are for sale in this batch; only a subset is shown below. For details, check with the model room.
Master Floor (6th to 21st floors)
Key Points:- The 7th-floor G-type northwest corner unit is about 14 million yen cheaper than in the previous Phase 3.
- Some lower-floor units facing west or southwest (middle units), overlapping with Crevia Tower Nakanoshima, are discounted.
- South-corner and east-corner units with river views have seen significant price hikes, with the south corner going up more than the east corner compared to last time.

Luxury Floor (22nd to 39th floors)
Key Points:- The Q-type northwest corner on the 24th floor, overlapping with Crevia Tower Nakanoshima, is 14 million yen cheaper than the previous Phase 3.
- The 23rd-floor N-type east-facing unit, which is just high enough to clear the Kanden Hospital line of sight, is cheaper than the previous phase (view must be confirmed, but there is a river view from the balcony).
- South-corner and east-corner units with river views have substantial price hikes.

Premium Floor (40th to 44th floors)
Key Points:- Prices remain the same as Phase 3 because they were already high to begin with.

Summary
As of now, a lot of units already have requests in, and multiple units have high lottery odds. So despite the fixed-term leasehold, this condo is popular… (Frankly, I didn’t expect it to be so popular…)Because more units are being offered in this phase and some are actually cheaper than in Phase 3, I think those discounted units are real bargains.
While some might grumble about the fixed-term leasehold aspect:
- The Parkhouse Nakanoshima Tower is already selling mid-floor units at over 6 million yen per tsubo, so even with a leasehold, there are some relatively attractive prices here.
- Multiple office buildings in Nakanoshima 5-chome will be completed by 2030.
- Two tower condos planned for Nakanoshima 5-chome are expected to be extremely expensive.
- The Naniwasuji Line is slated to open by 2031.
Between the “Brillia Shock?!” and the developer’s desire for a sell-out before completion, I’d strongly recommend checking out this Phase 4-1 if you’re considering buying!
That’s all for now! Stay tuned for my next blog update!
