Section 01
Why this site exists
The person running this site is Japanese, not a foreign resident. After watching foreign friends in Japan stuck with SIM plans that weren't really their best option, he wanted to help them find better ones — that's why this site exists.
Plans that are obvious choices in Japanese-language sources often don't show up in English blogs and guides. Or if they do, the information is two years out of date. This is a small site to close that gap.

Editorial principles
These are the rules we hold ourselves to. They exist because the affiliate-marketing space online is full of sites that don't.
- We only recommend SIMs we've personally used or tested. If we haven't put it in our own phones or in a colleague's phone, we don't recommend it. If we list a carrier we haven't used, we say so.
- Prices are verified directly from each carrier's website, not copied from older blog posts. Each guide on this site has a "verified" date. When prices change, we update the page or note that the information may be stale.
- We write what we'd tell a friend, not what makes us the most money. Affiliate commission rates differ wildly between carriers. The carrier paying us the most is not always the carrier we recommend. Our picks are based on what actually works.
- Comparisons are honest, not stacked. If a competitor is better for a specific use case, we say that. If our pick has weaknesses, we list them. Readers can tell when a comparison is rigged, and they should be able to.
- We don't write fake reviews or stuff articles with keywords. Every guide is meant to be read by a person who needs an answer to a specific question. SEO is a side effect of writing something genuinely useful, not the point.
- If we get something wrong, we fix it. Email us. Seriously. If you find a price that's outdated, a sign-up step that's changed, or a recommendation that no longer holds, we want to know.
Section 03
How the affiliate part works
Some of the links on this site are affiliate links. If you click one of them and sign up for the service, the carrier pays Pamoja a small commission. You pay the same price you would have paid going to the carrier directly.
This is how the site stays free and how we justify the time we spend keeping it updated. It's also why we have to be careful about the picks — readers can sense when a "recommendation" is really a paid placement, and we'd rather earn slowly with trust than quickly without it.
Specific things to know:
Commission does not influence our picks. The carrier paying the highest rate on the LINEMO/povo/Rakuten comparison is not LINEMO, but LINEMO is still our recommendation for most readers. We check this every time we update the site.
We disclose at the start, not buried in the footer. The footer of every page says the site uses affiliate links. The TL;DR of each article also makes it clear when a recommendation is one we earn commission on.
If a carrier we don't have an affiliate deal with is genuinely better, we still recommend them. ahamo, for example, doesn't have a well-known affiliate program in the foreigner market, but we still send people to ahamo when they live in rural Japan and need docomo's coverage.

Found a mistake. Have a question we haven't answered. Run a carrier and want to be on the list. All of these are good reasons to email.
