What was it like on the business side of running a development company in Japan?
Treasure president Masato Maegawa recounted the time he was called into Sega president Hayao Nakayama's office...
It was early 1995, shortly after the release of Dynamite Headdy. The value of the yen had just suddenly risen to a historical high against the US dollar, meaning all sales in the US now brought in much less money in Japan. Many Japanese companies, including Sega, were suffering.
Maegawa had already signed the contract for Dynamite Headdy: Sega paid ¥50 million (~$500,000) up front for development, plus ¥300 (~$3) royalty per copy sold in both Japan and the US. Notably, Sega was paying in yen per copy sold in the US rather than in dollars. However...
Sega president Nakayama called Maegawa into his office and said he was unilaterally revising the contract, despite the game already being released. For per-copy sales in the US, he crossed out ¥300 and wrote in $2.4.
It was necessary to switch to dollars, Nakayama said, because the appreciation of the yen would put Sega into the red otherwise. Maegawa was flabbergasted, since the revision would cost Treasure a lot of money, but he had no power to prevent it.
Nakayama made Maegawa stamp his hanko seal next to the changes to show he approved of them, even though Maegawa was thinking to himself, "This is illegal!" But he had no recourse if he wanted to continue working with Sega.
Maegawa later found out that despite this experience, Sega was perhaps the most generous publisher when it came to overseas sales. Many publishers would reduce the overseas royalty to 1/5 of what it was in Japan, making it hard for developers to profit from high sales outside Japan.
