2. Pros of J:COM NET

2. Pros of J:COM NET

For various reasons, you might be interested in J:COM NET. Below are a few of the pros that come along with making a contract with J:COM for internet services.

An inexpensive cable TV and internet set

If you’re looking for cable TV and home internet at the same time, J:COM might be the right choice for you. It is fairly inexpensive, and you can watch various important cultural events on Japanese TV.

For example, there is Kohaku, the annual New Year’s Eve singing battle. There is also the Hakone Ekiden, an annual foot race from Tokyo to Hakone and back over the course of two days. Many Japanese people travel home for the holidays and watch these events with their family on TV, and you can watch and be a part of the experience too if you sign up for a cable TV and internet set.

TranslationThen it’s no problem at all 🎵 J:COM is a little cheaper for wowow (channel) than SKY PerfecTV! (competing TV service) 👍I joined for wowow and to watch UFC 📺Holloway fun!!!

Use the internet within a week of applying

If you are worried about being able to use the internet after moving in, going with J:COM could put your worries at peace. After signing a contract, they make it a point to install your internet fast.

They say that the fastest installations take place just 4 days after a contract has been signed!

Note that if you live in an apartment or house that does not have J:COM installed, the installation process may take as long as a typical FIBER INTERNET.

TranslationI had tried to make a contract with NURO Hikari but ended up going with J:COM.
The landlord’s OK for the installation was given, and the preliminary inspection of the installation was completed, but it turned out that something was missing and the installation could not be done. It took a little over a month from the time of application to find out.
I contacted J:COM and the installation was completed in less than a week. That was fast.
Just to let you know…

Free router rental

J:COM NET offers a free Wi-Fi router rental when you sign up for their “Net + TV” plan. If you only sign up for internet, renting a router costs an extra 550 JPY per month.

TranslationI am very comfortable since I had my J:COM router replaced.

Internet speed: 73Mbps. What is your internet speed?

3. Cons of J:COM NET

3. Cons of J:COM NET

If you were thinking about making a contract with J:COM NET, wait to read some of the cons before going ahead with a contract!

Slow speed

We have found a few reviews online of some users complaining about the slow speeds that they get from J:COM NET. Below is a table of J:COM NET plans and the maximum download and upload speeds that are supported.

Course typeMax. download/
upload speeds
40M course40Mbps/2Mbps
120M course120Mbps/10Mbps
320M course320Mbps/10Mbps

Note that J:COM NET uses cable TV lines, which is why it is slower. Most modern internet service providers use the standard fiber optic lines, which allow download/uplaod speeds of up to 1Gbps.

J:COM NET’s 1G course uses au HIKARI’s fiber-optic line, so it has fast speeds. However, if you’re interested in fiber-optic internet, it would be cheaper to contract directly with au HIKARI, so there is no need to sign up with J:COM.

TranslationWhen I was at home, I couldn’t even watch movies on J:COM, which drove me crazy.
Now I am at peace with au HIKARI.

Persistent salespeople

There were reviews from some customers who have had bad experiences with J:COM and their staff. People have said that the J:COM salespeople are not very polite.

It seems that there are J:COM employees who go to various J:COM serviced houses to “check the TV reception” and do other sales activities during their regular inspections. For those who only plan to receive inspections, this may seem rude.

TranslationThe J:COM guy who came to do maintenance on the TV signal was a long talker.

After making a lot of small talk, he started to sell his services, which was really crappy.

Expensive if you don’t want cable TV

If you are just looking for internet services, there might be better options. The J:COM NET internet service is expensive by itself when compared to other faster fiber optic services.

I’m not using J:COM’s TV and phone services, and it even looks like I can watch TV without a contract, so I thought I’d just use the internet, and I did some research…
but it turns out that the price of a regular internet single unit is terribly expensive…

High cancellation fee

If you ever decide that you don’t want to use J:COM anymore, and want to cancel your contract within a two year period, they have a high cancellation fee. When combined with their removal fee of 4,800 to 9,800 yen, the total cost can go higher than 30,000 JPY.


My J:COM cancellation fee is 26,000 JPY.
That’s so expensive! (ʘ言ʘ╬)
