The organization over time
Each line starts at 100 in 2018, so what you read is the shape rather than the size: 150 means half as much again as 2018, 50 means half. The number beside each label in the key is where it ended.

Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2023 to 2024, from $736k to $406k (−45%).
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2018 36% · 2021 38% · 2022 41% · 2023 32% · 2024 44% · 2025 34%. Grants only. Government contracts and fees sit inside program revenue.
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 6 reported years ran a deficit.

the vertical line marks half of all grant income — 2 funders to its left
62% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund National Japanese American Historical Society Inc.
Largest funder’s share by year: 2017 63% · 2018 88% · 2019 71% · 2020 43% · 2021 83% · 2022 96% · 2023 56% — diversifying over time.

In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $172k arriving through sponsors registered in 3 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
