Bitcoin was created by Satoshi Nakamoto and release after the 2008 Leman Shock in the "Bitcoin White Paper". It was a response to corrupt politicians mis-managing the nation's wealth. Bitcoin separates money and state allowing a trusted protocol to control the money rather than the fallacies of man. The bitcoin protocol is base off a lot of the technology developed by the US government and other computer scientists.
There has been a lot of different types of money through history; shells, gems, coins and even cigarettes. Bitcoin as a money is unique since it satisfies most of the properties of money. Bitcoin at its base is a digitally encrypted decentralized distributed accounting ledger. It is a huge step up from the accounting ledgers that are sold on Amazon. The decentralization with autonomy allows bitcoin to be the first true global currency. As of 2023, El Salvador and Center Africa Republic have both adopted bitcoin as legal tender.

Despite the fear, uncertainty and doubt that media and political puppets like Greenpeace preach; bitcoin is GREEN! It inspires energy innovation and is one of the leaders of processing trapped energy.
All bitcoin transactions are made public on every node so how is bitcoin autonomous? Despite transactions being public they are all encrypted with SHA256 which even with a super computer would take millions of years to crack. Also bitcoin users can generate new addresses for every transaction so specific addresses also can't be followed or traced. Recently exchanges are wanting users to register their hardwallets and softwallets before they can transfer bitcoin to them. This compromises the autonomy of your accounts and I suggest purchasing your bitcoin through different means.
Before you buy bitcoin you should setup either a hard wallet (Bitcoin Network) or a soft wallet (Lightning Network). A wallet allows you to hold and spend your own bitcoin rather than an exchange, bank or external party access to your funds. Many exchanges have been hacked or have over leveraged their accounts leading to lose of users savings which has led to the expression, "Not your keys, not your bitcoin". It is necessary that you hold the keys (seed phrase) for your wallets or else it is a scam. A seed phrase is a 12~24 secert word phrase that will give you access to your account. Never type or save your seed phrase on the computer, they should only be typed on the wallet. For safe keeping it is best to have your seed phrase encoded and stored in three separate locations.
Hard wallet is similar to a savings account and can be setup on a device like a USB. Popular hard wallets are Trezor and ColdCard.
Soft wallet is similar to a checking account and can be setup on your cellphone for making easy purchases. Popular soft wallets are Muun and Samourai.
Once you have your wallet you can buy bitcoin in a couple of different ways...
Buy from a trusted friend or meet-up group. (Fiat)→(Friend)→(Bitcoin)→(Wallet)
Buy from an exchange. (Fiat)→(Exchange)→(Bitcoin)→(Wallet)
Register with an exchange: Banking information and personal information
Send money to exchange through bank account or convenience store deposit
Buy bitcoin on the exchange
Send bitcoin to private hard or soft wallet.
WARNING: Leaving your bitcoin on the exchange may lead to loss of all your investment. Unless you are a day-trader or don't mind the gains & losses tax burden I would recommend using bitcoin as a savings and checking account. Also please note that exchanges like bitFlyer have passed many KYC regulations making autonomy very difficult, often they won't allow bitcoin to be taken off their exchange without personal information being disclosed.
Buy from a bitcoin ATM. These are very rare in Japan and requires identification and tax reporting.
Mining bitcoin. This is probably the best approach but technical ability, cost of entry and energy consumption must be weighed into your decision.
