SimCity Buildit Tokyo Town Layout Guide – 4+ Million Population

SimCity Buildit Tokyo Town Layout Guide – 4+ Million Population

Hey Everyone!

New Beach Update for SC Buildit – TOKYO TOWN: This is version 4.1.6b of my Sim City Build It layout guide for a maximum population. As is clearly observable, this guide is subject to constant changes and updates along with the updates of the game and small tweaks here and there that evolve over time. DO NOT take this population figure as the HIGHEST number possible. If you have a suggestion to improve (with NO HACKS) please let me know!

This version of the guide uses only Tokyo Town residential zones. You can find a similar guide for full regular residential zones here . Feel free to mix and match between the guides as most people will have a mix of regular and Tokyo Town residential zones.


Today we have our SimCity BuildIt 4+ Million Population Layout Guide, with an overhead view and grid with buildings, services, and calculations and explanations as to why this guide looks the way it does.


Earlier version of the guide can be found either on this website (see change log further down) or on the SCBuildIt subreddit. A number of Mayors were part in the creation and tweaks of the layouts over time and they do deserve praise as well.

Utility Services

This layout uses a combination of space saving Tier 1 and more efficient and pollution free Tier 3 utility service buildings (more in-depth info here).


Important note: Tokyo Town zones provide 20% population, but also require 100% utilities. Be aware of this when building your Tokyo Town zones. This guide provides full coverage for 100% Tokyo Town zones.


Utility Buildings

Waste Recycling Center (Tier 3)


Coverage Services

This guide uses a combination of Tier 1 and Tier 3 coverage services to provide fire, police and health to Sims (in-depth info here).

Specializations (NEW INFO wit more recent updates)


Earlier Versions: Parks, Education and transportation could EACH provide coverage area to reach 100% population boosts to all residential areas. This means maximizing each of the three specialization and overlapping their coverage areas provides 300% total boost. Gambling, Entertainment, Landmarks COMBINED allowed a coverage area to reach 100% population boost. Unlike the specializations above, you could reach a MAX of 100% using any combination of the three. Gambling was used because it is the cheapest specialization to provide 100% coverage (20 keys). (in-depth info here).


Recent Updates: The developers recently fixed this issue so now the game allows each specialization to provide a 100% population boost. This opened very different layout possibilities and made it possible to reach far higher population numbers.



Specialization (Each: 100% | Combined 700%) Buildings
Parks Peaceful ParksSakura Parks
Education University
Transportation Helipad
Gambling Luxury Casino (Not Luxury CasinoTowers)
Entertainment Ferris Wheel
Landmarks Washington Monument
Beach Luxury MarinaRelaxed Beach


This means that you can have a total of 700% boost to any residential zone allowing population numbers above 3.6mil of the regular layout and even above 4.1mil for a full Tokyo Town city.


NOTE: (many have asked about why we use Luxurious Casino versus Luxurious Casino Tower): The maximum amount of boost you can receive from a specialization is 100%. Overlapping two of the Luxurious Casino Tower (which give 60% boost each) would result in a 120% boost (20% wasted). So stick with the Luxurious Casino and you can save the golden keys. The layout requires enough keys as it is and saving some is always good. If you want to have more diversity in your buildings, you can mix them as well. The boost numbers will not change.


Places of Worship

Many have asked why there are no Places of Worship on the max layouts. The explanation for this is simple. They do not provide enough population boost to make them worthwhile. A church takes up 2×2 and provides 25% boost for a 12×12 space. The space it take up produces a residential zones loss of 1836 + approx. 600%, so roughly 13,000. The place of worship would have to cover approx. 28 residential zones, which is not possible for the coverage ratio.



One of the bigger changes in this layout from the last is the massive reduction of parks. Here again, we are looking at the same general issue as we are seeing with places of worship. For the past layouts I have been using mostly peaceful parks. They have a coverage ration of 7×10 in the game. As you can see in the screenshot below one peaceful park can only cover 19 residential zones max.


Screen Shot 2015-08-04 at 1.31.01 AM


2 Peaceful Parks together can cover the below area, providing 19x2x459 = 17,442 population boost. But you need perfect coverage for that, which this layout does not allow. Please see below for a table that shows how many res units have to be covered by the both parks together. For this each park needs to be accounted for separately. For the layout I picked the spots for parks that actually outperform their loss. I have marked park coverage on the layout further down with RZ and RZ-1 – 4 corresponding to how many 25% park boosts the residential zone gets.


Boost Total Red Pop Req. Res Coverage
500% 11016 24
600% 12852 28



Under current circumstances it is very difficult to get 100% education boost into the layout. For the people that like tweaking my layouts even further I have provided a more transparent calculation base for the education specialization. All residential zones that receive 50% boost are highlighted in a double white line around the zone. All other residential zones have 100% boost.



With the beach layout additional population boosts are now possible. Upon looking at the different options it proved that Luxury Marina’s provided the best coverage and overall population boost. I have highlighted the rows on the side of the layout to which height the Luxury Marina boosts are effective.


Update: To everyone that thinks that Sailormens Piers are more effective. I have checked this with the current layout and I concluded that Luxury Marinas provide about 1-2k more population and are way cheaper in terms of keys (about 370 keys less). If you want a more in depth proof of this, please let me know and I will gladly go through the calculations with you.



Many people have asked why there are no factories on the max pop layouts. The answer to this is that factories are no longer necessary in the late endgame. At this stage every single build able spot is accounted for and only the last few buildings need to be upgraded to skyscrapers. At tho point this can be achieved through the Global Trade Head Quarter or through feeder cities. You can also leave parks or other boost structures out until all buildings are constructed if that suits your playing style better.


Cost – Simoleons

This is an expensive layout in terms of simoleon cost. Especially the expenses for the road upgrades are extremely costly. Upgrading to Streetcar level is not always necessary. Also, simoleons simply accumulate over time with taxes. Don’t worry too much if you need to wait a few days for certain road upgrades or new utilities buildings, the keys are much harder to farm.

Keys – Most bang for my buck

For this current layout guide I went a step further and checked what is the most efficient use of our hard earned keys. Where do I get the most bang for my buck so to say. Please see below table based on the current layout in this guide.


Structure # Cost Total Keys Boost/Key
University 8 25 200 2,907.96
Ferris Wheel 8 28 224 2,383.96
Helipad 18 20 360 1,664.49

Was Mon 18 40 720 832.24
Luxury Marina 8 50 400 522.95
Relaxed Beach 1 12 12


As you can see the Luxury Casinos clearly top the chart followed by University and Ferris Wheels. Landmarks and the beach section might look nice, but are by far the worst way to spend keys with the aim for max population. Since the relaxed beaches have such little effect on the total beach calculation I have simply added them together. I will leave it to each of you Mayors to pick and choose the best individual way to spend the keys.

  • Tom Cravens

    Is it me or is the entry one row off

  • Philip Ocampo

    You misplaced your entry road tile. Just adjust it one down and swap the 2 admin buildings with a fusion reactor. 🙂

    • Timm Baur

      Saw that right after the post went up. Already fixed for next version.

  • Chris Dixon

    How do you get that beach layout? Both the RB and Marina have dependencies. How would you purchase the final Marina once you’ve bulldozed the pre-req buildings to create the space?

    • Zegerman

      Thanks for noticing that. The left Relaxed beach should have been deleted. Then it will all work. That one has no boosting effect anyways. Already fixed for next version.

  • JC

    If you rotate the whole layout clockwise 90° do you end up with a higher population due to increased beach coverage?

    • Zegerman

      Hi JC. I just spend a good time testing your hypothesis. Unfortunately it does not work in the favor of turning the layout:



      • JC

        On the image, dark red is beach coverage correct?

        • Zegerman

          One is marina, the other relaxed beach coverage

  • EverestCity

    You don’t have full casino coverage on the south (beach) side, the last row only has 50% coverage.

    • Zegerman

      Already fixed for the next iteration. Thank you.

  • EverestCity

    You don’t have full coverage for entertainment on both the East and West sides, several rows only have 60% coverage.

    • Zegerman

      Already fixed for the next iteration as well. I did not update all my formulas properly initially. Thank you.

  • Marcelo Ferreira

    That Layout doesn’t work, i followed from scratch and it’s missing a lot of things.

  • Developer58

    There is no full Police coverage on the row above the beach: from the 4 RZ/TT in the middle there is always 1 zone not covered. Tried moving roads, but no luck.

    • Eric Hood

      This is true. Replaced them with parks.

    • Zegerman

      Have the police face the side road, then it provides the needed coverage

      • Developer58

        Tnx, that works

      • Valentine

        How do you turn the police to face the side road ? Mine only wants to face the main road…

  • LC

    How do you get the tall buildings? I seem to max then out. But they are not growing anymore?

    • Karolis Masilionis

      to get a skyscraper you need to start a building from scratch in the luxurious zone, to check where are the luxurious zones you need to click on the helmet in the residential buildings section

  • hokieland

    Long time lurker, first time commenter.
    Apologize in advance if these have already been answered, I did not see it here.
    1. I am one expansion away from fully expanding the beach (very right expansion is 20 of each belts,wheels,scuba masks). I currently have the light house, the sailorman’s pier, and 6 luxury marinas. Once I complete the final expansion I am going to get another pier, then bulldoze my lighthouse, then get 2 more marinas. I will set it up like your diagram with the piers on the edges in place of your relaxing beaches with the 8 marinas in between. This allows for two piers instead of two relaxing beaches (30% vs 20% adder, and a wider affected zone from the piers so the left one isn’t wasted). And allows for both piers to be obtained with the light house prerequisite before bulldozing the light house. Then allows for the final marinas to he obtained with the pier prerequisite. Has this been discussed and why wasn’t this path chosen?
    2. Why does the current layout include the one single water tower? Layout has 10 pumping stations, at 55 units each, = 550 units. This is the same coverage as the 10 sewage plants at 55 units each = 550 units and more than the coverage of the fusion plants and 15 wind towers at 540 units total. Why the addition of the single water tower to take the water coverage to 559 units? Wouldn’t this space be better reserved for one additional wind tower to take power coverage to 549 units? Or if that’s not needed just another Sakura park?
    2b. Also note the calc table lists 15 wind towers at 8,000 simoleons each. Wind towers are 6,000 each. So the 15 wind towers only costs 90,000 not the 120,000 listed.

    Thanks, happy simming.

  • Aaron Lineberger

    Entrance road is not correct in your layout. in the game it is 14 from the beach, in your map it shows 15 from the beach. Good job on the calculations though. 😀

    • Wagner De Andrade Perin

      Is it true!! No space for trash here.

  • Jody Kinser

    Has anyone attempted this TT max layout? The main road connection to the city on the left doesn’t line up with this layout!!!!

    did you see Lux Marina covers 50% more tham sal pier, but it also needs 500% more space? 50x piers isnt better tham 8x lux mar ?

  • Marcos

    Hi Zegerman,

    Could you test this one? Basically the same, parks included. Total: 238 TT’s

  • Marcos

    Hi Zegerman,

    Could you test this one? Basically the same, parks included. Total: 238 TT’s

    • Wilmer Maristaza

      where do you place the factories??

    • ohisok

      a quick population calculation for your layout:
      244 x 2204 x 740% (assuming all 100% boost but beach coverage cannot go beyond 40%) = 39779542, thus total population will not exceed 4 million

  • Kruser

    The one thing I’m confused by the layout is why do you have so many utilities? Isn’t the utilities far more than is needed?
    Fusion Plants, you have 6 of them and each fusion plant services 75 homes. 6 * 75 = 450. Doesn’t your example only have 272 homes in it? That’s an excess of 178. Wouldn’t you only need 4 fusion plants? Then on top of that, you have wind plants too.
    Trash, you have 8 of them and each recycling center services 70 homes. 8 * 70 = 560.
    Sewage ad water. you have 10 each. Each one services 55 homes. That’s 550 of each.
    What am I missing? Do Tokyo Towers count as two or something? 272 * 2 = 544?

    • Marcos

      Tokyo Town utility requirement is 2 per building.

  • Thomas


    I can’t see the Department of Culture, and the others Department.
    Have you destroyed them ?

    • ohisok

      once the structures needed are built, departments are no longer needed on the map

    I strictly respected your plan but the happiness is only 99%… something wrong?

    • ohisok

      park coverage is not 100%

  • Jeremy Barker

    What do you use to create your layouts? Is this an app that can be downloaded?

    • ohisok

      ms excel

      • Jeremy Barker

        Is there a link to the excel file?

        • ohisok

          i mean it is created from a blank sheet

  • Kryndude

    May I ask why you didn’t fill the first row adjacent to the beach with residential zones? I’m gonna follow your current layout cuz it’s neat, but I’m still curious if you can get more population boost by replacing some of the shops and water pumps with RZs.

    • Petch

      Tokio Towns require 2 times more utility service and you can’t destroy shops.

      • Kryndude

        I meant switching location with the first RZ row on the top and then adjusting other services a bit. That way more RZs can get beach pop boost right?

  • ohisok

    my modification to your layout with population at 4023061;
    all residentials covered by parks, 100% happiness 🙂

    • Thomas

      there is a problem with the access road, no ?

      • ohisok

        road connection to the highway is not necessary so i put a sakura park there instead 😉

        • Linda Spicer

          Nice, only downside is would set you back $600 real dollars to make, atleast with the other builds you could possibly build it for free given enough time.

  • Linda Spicer

    The calculations aren’t right. Ferris wheel is only 20×20 so only covers 9 spots on both left and right as opposed to I’m assuming 11 that you have ie you have is at 24×24. So 90 res. have 60% coverage instead of 72. And some of the Sakura parks seem to be 10×10 instead of 8×8. All in all after you adjust those I got a total pop. for your build of 4002409. Currently doing own build before coming across this site, but mine is 4184 less than that recalculated amount. I suspect that may be because mine is vertical as opposed to horizontal and requires piers instead of marinas. Marinas don’t go well with vertical build since some spots will be only getting a 30% boost

    • Linda Spicer

      Found more errors, your university covers less than you have reported, with that your number falls below 4 million. Though if you use more parks you could probably get above 4 million again, though don’t know for sure.

  • ohisok

    my second modification replacing marinas with sailor piers and a lighthouse, giving a population at 4050855 🙂

    • Giuseppe

      man can you find a way to put the main road acess XD i know it doesnt affect anything but it feels wierd, i speak as a perfectionist XD

      • Giuseppe

        or if i take sakura park and on line 37 still 100% happiness?

        • ohisok

          yes you can replace row 37 left sakura park with road and it will be still 100% happiness

    • Akasone

      i used your layout
      But If i don’t use cash park(instead peaceful park)
      your layout only have 3,890,000 populations.
      So, Someone who don’t wanna pay cash had better to use Zergmen’s layout rather than yours.

      • Akasone

        my layout population can reach 4,090,000 if i buy all the cash park.
        now, 4,070,000 🙂

  • Mihai Vazan

    I filled the map, strictly following your layout (+4 mil)…the result is 3.966.887 population with 99% happiness… So the original layout is just a theory or someone else really obtained over 4 mil pop.?
    if I modify the building line no 17 and changed few peaceful parks with pumpkin man statue parks… I have 3.978.458 population with 100% happiness but not 4 mil.

  • Owen Hertzs

    I believe if you were to move all the shops and pump stations near the beach up to the top of the map and shift all the rest of the structures down you would be able to get more coverage with the marinas. I’m new to the game and cant really test this but when i get that far I will for sure. You will be short 1 tile having to add a road to access the top though… Shouldn’t be too difficult to solve.

  • Thomas

    Hi, with the new update (bigger map !), can you please release a new layout ?

  • Johnny

    Is the Luxury Marina really the best option? I ask because since it’s so wide, it doesn’t have that much opportunity to double up on the bonuses. What if we put the Sailormans Pier across the board instea?

  • rtc

    I just recently hit 4,613,800 using the layout as a base but then did trial and error moving stuff around. Also still have land that is unused and only half the beach is open. Thinking 4.8 million might be possible.
