Japan has three major networks: NTT Docomo, au (KDDI) and SoftBank. Docomo is the largest and has the best national coverage, including in the countryside and mountainous areas. au and SoftBank are strong in the cities, but SoftBank can perform slightly worse in the countryside and in tunnels. Networks: NTT Docomo, au (KDDI), SoftBank.
For a round trip with navigation, translation apps and social media, around 1 GB per day is enough. Those who look up a lot of routes or stream on the train are better off with a larger package.
On the shinkansen bullet train, Docomo and au hold the signal best between the tunnels, while SoftBank sometimes drops out there.

Yes, along all major shinkansen lines such as Tokyo to Osaka there is good coverage. Between the many tunnels, Docomo and au hold the signal best, while SoftBank occasionally drops out there. A travel eSIM that roams on the strongest network gives the most stable connection.
In most rural areas the network works well, especially via Docomo, which has the broadest coverage. Very remote mountain or rural areas may briefly be without signal, but for the usual tourist routes the coverage is excellent.
