Is Lower Rent Always Better? Comparing the Total Cost of Living for Six Months or One Year ～ Column｜Share House and Rent vol.4 ～

Hello! Come on UP operates small, community-focused international share houses in Tokyo, Yokohama, Osaka, and Kyoto, where Japanese and international residents can naturally connect. Each house has its own concept and atmosphere, creating opportunities for new encounters and a new way of living in Japan.

You find an apartment for:

¥60,000 per month.

You think:

“Great. I can live in Japan for ¥60,000 a month.”

But is that really the full cost? Over the previous three articles, we have looked at rent and initial fees. Now let’s look at the bigger picture:

How much will you actually spend over the entire period you live there?

Can a ¥60,000 Apartment Require ¥300,000 Upfront?

Major Japanese housing websites such as SUUMO, At Home, and LIFULL HOME'S commonly explain that initial rental costs can equal roughly four to six months of rent, depending on the property.

If rent is ¥60,000:

that could mean approximately ¥240,000–¥360,000 before moving expenses and furniture.

Of course, some properties have no key money or offer lower agency fees. But:

“¥60,000 rent” does not necessarily mean you can move in with ¥60,000.

Break Housing Costs Into Four Categories

Housing expenses become easier to understand if you separate them into four groups.

1. Non-refundable move-in costs

Key money, agency fees, contract fees, administrative fees, insurance, and similar expenses.

2. Money temporarily held

Deposits or security deposits that may be partially refunded depending on the contract.

3. Monthly costs

Rent, management fees, utilities, internet, guarantor company fees, and other recurring charges.

4. Costs required to start living

Furniture, appliances, bedding, and moving expenses.

Instead of comparing rent alone, compare everything you need to actually live there.

What If Come on UP Rent Is ¥60,000?

For example, imagine a Come on UP room with rent of ¥60,000. Under the standard conditions:

Rent: ¥60,000

Utilities: ¥10,000

Security deposit: ¥60,000

So the amount required for the first month would be approximately ¥130,000 in this example. Furniture can be added for ¥3,000 per month if necessary.

This is only an illustrative example. Actual rent and conditions vary depending on the room and property.

Can We Simply Say “¥300,000 vs. ¥130,000”?

No. That comparison would be too simplistic.

A standard apartment’s initial cost may include a refundable deposit. Come on UP also requires a security deposit.

So you should separate:

money you actually lose

from:

money you temporarily deposit.

This is why the phrase “Initial cost: ¥XX,XXX” does not tell the whole story.

What If You Are Only Staying in Japan for One Year?

This is where the calculation becomes especially relevant.

Maybe you are:

an exchange student,

a working holiday resident,

an intern,

a researcher,

or working on a one-year project in Japan.

If you are only staying for six months or one year, it may feel wasteful to:

buy a refrigerator, buy a washing machine, buy furniture, sign internet contracts, pay large rental fees,

and then sell or dispose of everything before leaving Japan.

In this situation, the costs at the beginning and end of your stay can represent a large part of your total housing expense. If you plan to stay for five or ten years, buying your own furniture and signing a standard rental lease may make much more sense.

So:

the “cheapest” housing option changes depending on how long you plan to stay.

Is Your Time Also Part of the Cost?

There is another cost that does not appear on the rental listing:

time and paperwork.

Depending on the apartment, you may need to separately arrange:

○ guarantor company

○ insurance

○ electricity

○ gas

○ water

○ internet

○ furniture

○ appliances

If you have just moved to Japan and your Japanese is limited, each of these steps can take additional time and effort.

At Come on UP, no guarantor company is required. The application generally uses:

proof of income or savings + an emergency contact.

Residents also do not need to individually open new utility and internet contracts for the house.

For someone arriving from overseas, sometimes the real value is not only:

“How many yen can I save?”

but also:

“How quickly and easily can I start my life in Japan?”

Is the Cheapest Rent Always the Best Choice?

After four articles about housing costs, the conclusion is simple:

A share house is not always cheaper.

If you already own furniture, plan to stay for many years, and strongly value having a completely private home, a standard apartment may make more sense.

But if you:

◎ Want to reduce upfront expenses

◎ Do not want to buy furniture and appliances

◎ Plan to stay for several months to a year

◎ Want to simplify the process of moving into Japan

a share house may be a very practical option.

And housing has one more type of value that cannot be calculated in yen.

You can return to an empty apartment every night. Or you can have your own private room while knowing that someone may be in the living room when you feel like talking.

Even if both options cost ¥70,000 per month:

Are they really the same kind of living experience?

That is exactly what we explore in our next column series:
